This is another advance in my studies to enable a more economically viable version for the Monster Mask.This wonderful project has been developed by the Adafruit team, but import taxes in Brazil are extremely high. Especially when the goods come from the United States.The first version I built used Teensy 3.2. Then I did some experiments with the Raspberry Pi Pico and finally came up with this solution using the Xiao RP 2040, which combines the best of both worlds: it has the same processing power as Pico and is smaller than the Teensy.In the next stage of the project, I must add light sensor, joystick and why not, sound. I'm working on an accessory board for XIAO that will add these functions.First - Add XIAO RP2040 to your Arduino IDE: https://wiki.seeedstudio.com/XIAO-RP2040-with-Arduino/Second - Install Bodmer TFT_eSPI Library: https://github.com/Bodmer/TFT_eSPIBasically the same work I described in my other tutorial for the Raspberry Pi Pico: https://www.pcbway.com/project/shareproject/Raspberry_Pi_Pico_with_GC9A01_Round_Display_using_Arduino_IDE_and_TFT_eSPI_Library.htmlThe developer of this library made it much easier to configure the different types of display with the different types of controllers. To change the settings, you can create a specific USER_SETUP file and change things like the pins used, the spi clock speed, the type of display used, etc...To do this, go to the library folder in Libraries/TFT-eSPI-master/User_Setups/ and create a file called Setup62_XiaoRP2040_GC9A01.h with the following content:// USER DEFINED SETTINGS // Set driver type, fonts to be loaded, pins used and SPI control method etc // // See the User_Setup_Select.h file if you wish to be able to define multiple // setups and then easily select which setup file is used by the compiler. // // If this file is edited correctly then all the library example sketches should // run without the need to make any more changes for a particular hardware setup! // Note that some sketches are designed for a particular TFT pixel width/height #define GC9A01_DRIVER // Round TFT SPI Display #define TFT_WIDTH 240 // ST7789 240 x 240 and 240 x 320 #define TFT_HEIGHT 240 // GC9A01 240 x 240 #define TFT_MISO D9 // RX PIN - Not Connected #define TFT_SCLK SCK #define TFT_MOSI MOSI // TX PIN #define TFT_CS SS // Chip select control pin D7 #define TFT_DC D4 // Data Command control pin #define TFT_RST D5 // Reset pin (could connect to Arduino RESET pin) #define TFT_BL -1 // LED back-light control pin #define TFT_BACKLIGHT_ON HIGH // Level to turn ON back-light (HIGH or LOW) #define LOAD_GLCD // Font 1.

Blinking Christmas StarThis is a board developed for Julialabs PCB Challenge 2021 with a Christmas theme.It just need a 3V CR1220 batter cell power to automatically start over with a predefined (by software) LED sequences that highlights the main eight star corners, alternating the 4 inside corners (blue LEDs) with 4 outside corners (White LEDs), taking full circle clockwise and counterclockwise blinking, and some all on and all off LEDs between this sequences.The software was developed using PlatformIO for VSCode IDE using the little Attiny85 SMD mounting and can be found at this github repository (with another project files).It was used SOIC packages and easy manual soldering SMD components for an equally easy DIY experience on mounting.LEDs must be placed with side (turned do same directions) or, if possible with a bottom orientation (that could be possible with some turnaround at soldering time) taking the better from translucid parts of the board.All the process (from concept to the delivery of this project on PCBWay) was lived streamed at Twitch and some of this development will be highlighted to Youtube later.

This uses common resistors and parts, the only parts that may require special consideration are the Arduino Pro Mini (make sure you get the correct type, 5V/16MHz with a matching pinout to the PCB), and a 0.96" I2C OLED display.The latest firmware will be available to download from my website: https://www.TheDefpom.comI decided to use through hole components to make the project easier to assemble, it is a bit old school but I think it is more suitable for this purpose.The 150 Ohm resistors are there to provide protection in case the IC being tested has a short circuit, similarly there is a 33 Ohm on the main power supply rail for the same purpose.The 2N3906 is used to turn the power on/off to the IC so it is only powered during testing, the LED built into the Pro Mini indicates when power is on (and flickers after each test is complete).I will be publishing videos about this project in the coming weeks on my YouTube channel also, in case you want to see it in action: http://www.youtube.com/TheDefpomSo far I have done a "Short" showing the prototype version working: https://youtu.be/RAYK1XHOOk8there will be more videos about it soon.

Tento shield pro RaspberryPi vznikl z d?vodu pot?eby ovládání dal?ích periferií na 3D tiskárně, za pou?ití tiskového serveru. Vět?inou toti? bě?í tiskovy server na malém po?íta?i (RaspberryPi), ktery disponuje i vstupně vystupními porty (GPIO), které je mo?no pou?ít pro ovládání periferií tiskárny. V dne?ní době prakticky v?echny tiskové servery (Repetier server, OctoPrint, Klipper), umo?ňují jejich ovládání. Nicméně aby bylo mo?né tyto GPIO pou?ít je nutné je vybavit dal?í elektronikou a to hlavně posílit jejich proudové zatí?ení a zvět?it jejich napě?ové úrovně. A právě k tomu je tento shield ur?eny. Kromě samotného roz?í?ení GPIO obsahuje i vestavěny DC/DC měni?, kterym je mo?no p?ímo napájet p?ipojeny po?íta? (RaspberryPi), p?ípadně dal?í periferie. V?e je uzp?sobeno jak mechanickym, tak elektrickym provedením, aby tento shield pasoval p?ímo na RaspberryPi a sou?asně umo?ňoval p?ipojení dal?ích modul?, jako je nap?íklad TFT dotykovy displej. Z toho d?vodu jsou některé GPIO vynechány a shieldem pouze prochází skrze oboustranny konektor 40pin. Toto ?e?ení umo?ňuje vytvo?it velmi maly, ale zároveň poměrně vybaveny tiskovy server. Pokud pak Va?e tiskárna nedisponuje nap?íklad ovládáním osvětlení, nebo senzorem filamentu, m??e tyto funkce p?evzít právě tiskovy server bez toho, aby bylo nutné jakkoli zasahovat do stávající elektroniky tiskárny a to v?etně jejího firmware. Pokud pou?íváte pro ?ízení tiskárny firmware Klipper (d?razně doporu?uji), je integrace tohoto shieldu opravdu jednoduchá.Technické specifikace:Napájecí napětí 8-30V DC (DC konektor 5,5 x 2,1mm)Po?et opticky oddělenych vstup? 3xPo?et vykonovych vystup? 5xProud z vykonového vystupu 1A na ka?dy vystup (pouze p?i volbě 24V)Volitelné napětí vykonového vystupu 12V (max 1A v?ech 5) / napájecí napětí (24V)Napájecí vystup 5V ji?těny pojistkou max 1AVystup pro LED pásek WS2812B 5V / max 1A (max 20 LED)Zvuková signalizace Piezo měni?I2C rozhraní 2x konektor (3,3V logika)UART 2x konektor (1x 5V a 1x 3,3V logika)Universální OI port 1x 3,3V IO port (nap?íklad OneWire)P?ipojení k RaspberryPi 40pinovy konektor (pr?chozí)Podporované RaspberryPi ZeroW, Zero 2W, 3, 3B, 3B+, 4BNapájení RaspberryPi P?es 40pinovy konektor 5,1V/2,5AZapojení shieldu:Jak u? jsem v úvodu nazna?il, tato deska se zasouvá do 40 pinového konektoru RaspberryPi. Její provedení p?esně kopíruje po?íta?e RaspberryPi 3, 3B, 3B+, 4B, ale je mo?no ji pou?ít i s variantou ZERO. V takovém p?ípadě v?ak doporu?uji vykonněj?í variantu ZERO 2W, které utáhne bez problému libovolny tiskovy server a to v?etně TFT dotykového displeje. Pro p?ipojení je pou?it oboustranny konektor, tak?e lze nad tuto desku p?ipojit nějakou dal?í. To se právě vyborně hodí p?i pou?ití s TFT displejem. Z toho d?vodu jsou některé vyvody tímto shieldem nepou?ité, aby nekolidovaly s displejem.Shield je rozdělen do dvou ?ástí. Jednou je napájecí DC/DC měni? a druhou pak samotné vykonové roz?í?ení GPIO vyvod? po?íta?e. Jako DC/DC měni? byl pou?it obvod XL4004, ktery je poměrně vykonny a vy?aduje minimum externích sou?ástek. Vystupní napětí je mo?no lehce regulovat kolem hodnoty 5V, p?i?em? maximálně jde nastavit 5,2V, co? by mělo byt je?tě bezpe?né pro p?ipojeny po?íta?. Nicméně doporu?uji p?i o?ivování, nastavit hodnotu na 5,1V. Díky tomuto měni?i je pak mo?no cely tiskovy server napájet p?ímo ze zdroje 3D tiskárny nebo libovolného napájecího adaptéru 8-30V. Poměrně ?asto se toti? stává, ?e pokud je Raspberry napájeno pomocí microUSB, je na kabelu a konektoru poměrně zna?ny úbytek napětí a po?íta? pak m??e pracovat nestabilně. Tento problém je tedy tímto měni?em eliminován. Sou?asně se dá napětí 5V je?tě pou?ít pro napájení nap?íklad chytrych LED pásk? WS2812B, kde m??e byt p?ipojeno a? 20 LEDek. Tento vystup napětí je pak ji?těn vratnou pojistkou (1A), aby v p?ípadě jakékoli poruchy (zkratu) na LED pásku do?lo k jeho odpojení bez toho, aby to ohrozilo funkci po?íta?e. P?ípadně je mo?no p?ipojit je?tě do samostatné svorky X5 dal?í 5V za?ízení. I tento vystup napětí je chráněn vratnou pojistkou (1A).Druhou ?ástí je pak samotné ovládání GPIO z po?íta?e. Proto jsou na desce 3 opticky oddělené vstupy pou?itelné nap?íklad pro dodate?né senzory filamentu nebo koncové spína?e. Pro vykonové ovládání je pak k dispozici pětice vystup?, kterym m??eme nastavit vystupní napětí 12V nebo 24V respektive napětí pou?ité pro napájení (konektor US2). O napájení 12V se stará maly DC/DC měni? s vystupním proudem max 1A. Proto je nutné dbát toho, aby tento proud nebyl p?ekro?en. Pokud je vystupní napětí nastaveno na 24V je mo?no z ka?dého vystupu odebírat proud 1A. Samoz?ejmě je mo?no jednotlivá napětí kombinovat a nastavit nap?íklad na 2 vystupy napětí 12V a na zbylé 3 vystupy 24V. Pak ka?dy 12V vystup m??e poskytovat proud 0,5A.No a poslední takovou men?í ?ástí jsou komunika?ní sběrnice. Máme k dispozici 2 konektory I2C a 2 konektory UART, p?i?em? jeden konektor UART pou?ívá 5V logiku v?etně napájení a druhy 3,3V logiku v?etně napájení. To se m??e hodit, pokud pot?ebujeme p?ipojit nap?íklad 8bitovou ?ídící desku s 5V logikou nebo 32bitovou desku s 3,3V logikou, bez toho abychom museli tyto signály upravovat. V?e je u? vy?e?eno na desce Shieldu. Konektor ozna?eny OneWire lze pou?ít jako univerzální vstupně/vystupní a lze k němu p?ipojit nap?íklad teplotní ?idlo DS18B20.Do zbylé mezery na PCB se mi poda?ilo, je?tě vměstnat piezo měni?, tak?e lze pou?ít i zvukovou signalizaci.Schéma zapojení:Obrázek v plném rozli?ení je sou?ástí elektronické dokumentace.Schéma osazení:Obrázek v plném rozli?ení je sou?ástí elektronické dokumentace. O?ivení a montá? shieldu:P?i o?ivování musíme pouze nastavit vystupní napětí DC/DC měni?e trimrem TM1 na hodnotu 5,1V. Tím je ve?keré o?ivení hotovo.I samotná montá? by neměla ?init ?ádné potí?e, neb shield se pouze zasune do konektoru na RaspberryPi. Doporu?uji pou?ít distan?ní sloupky (M2,5), které shield zafixují ve správné pozici. Krabi?ka(y):Pro jednotlivé varianty sestav vzniknou modely krabi?ek, které bude mo?no vytisknou a celou sestavu tak vhodně zakrytovat.

Firmware Klipper se skládá v podstatě ze dvou ?ástí. Samotny firmware bě?ící v ?ídící desce, je? ovládá 3D tiskárnu a aplikaci, která bě?í v ?ídícím po?íta?i vět?inou RaspberryPi nebo podobném (OrangePi). Toto rozdělení umo?ňuje maximálně vyu?ít vypo?etní vykon RaspberryPi a do ?ídící desky, která m??e byt zalo?ena na 8bitovém MCU ji? posílá p?edp?ipravené p?íkazy, které deska (MCU) pouze vykoná. Dal?í velkou vyhodou je mo?nost p?ipojit k hlavnímu po?íta?i (RaspberryPi) hned několik ?ídících desek, a tak roz?í?it mo?nosti tiskárny. A jak jistě v?ichni víte samotny po?íta? RaspberryPi obsahuje hned několik GPIO, které jsou napojeny na tento shield. Tak?e se nabízí mo?nost je vyu?ít jako roz?í?ení ke stávající ?ídící desce. Z tohoto d?vodu musíme na Raspberry je?tě kromě samotného Klippru doinstalovat podporu MCU, které bude ovládat GPIO (o samotné instalaci Klippru se zde nebudu rozepisovat, ale m??ete se podívat do diskuse ZDE). Tak?e se na to poj?me podívat. V první ?adě pokud máte na RaspberryPi zprovozněn Klipper se p?ipojte p?es SSH a dále postupujte dle instrukcí: cd ~/klipper/sudo cp "./scripts/klipper-mcu-start.sh" /etc/init.d/klipper_mcusudo update-rc.d klipper_mcu defaultsNyní musíme zkompilovat firmware pro MCU RaspberryPi:cd ~/klipper/make menuconfigV sekci Micro-controler Archytecture vybereme Linux process a ulo?íme Q a Y. sudo service klipper stopmake flashsudo service klipper startNyní je podpora MCU z RaspberryPi nainstalována a ji? sta?í definovat do konfigura?ního souboru printer.cfg funkce pro tento MCU.?ást konfigura?ního souboru tiskárny, kde jsou definované vystupy, m??e vypadat nap?íklad takto:[mcu host]serial: /tmp/klipper_host_mcu [output_pin beeper_RPi]pin: host:gpio22pwm: Truevalue: 0shutdown_value: 0cycle_time: 0.001scale: 1000 [output_pin Svetlo]pin: host:gpio5value: 0shutdown_value: 0 [output_pin PS_ON]pin: host:gpio6value: 0shutdown_value: 0 [output_pin FAN-1]pin: host:gpio13value: 0shutdown_value: 0 [output_pin FAN-2]pin: host:gpio19value: 0shutdown_value: 0 [output_pin FAN-3]pin: host:gpio26value: 0shutdown_value: 0Zde si v?imněte, ?e jako první je definováno MCU host a dále pak ji? jednotlivé vystupy. V?dy p?ed definicí ovládacího pinu musí byt uvedeno, na ktery MCU je tento pin p?ipojen (pin: host:gpio20).Nyní m??eme konfigura?ní soubor ulo?it a restartovat firmware. Následně u? m??eme p?es u?ivatelské rozhraní dané vystupy ovládat.Pokud by se Vám nechtěl firmware spojit s MCU v RaspberryPi a hlásil, ?e nem??e najít cestu k sériovému portu na adrese: /tmp/klipper_host_mcu doporu?uji RaspberryPi vypnout a zase zapnout. Pokud by problém dále p?etrvával, m??ete zkusit p?idat u?ivatele pi do skupiny tty p?íkazem:sudo usermod -a -G tty pi Tímto bychom měli vy?e?ené ovládání vystup?, ale je?tě si uká?eme jak pou?ít vstupy nap?íklad jako detektory filamentu. ?ást konfigurace je zde:[filament_switch_sensor Filament_1]pause_on_runout: Truerunout_gcode: M25switch_pin: host:gpio12 [filament_switch_sensor Filament_2]pause_on_runout: Truerunout_gcode: M25switch_pin: host:gpio16 [filament_switch_sensor Filament_3]pause_on_runout: Truerunout_gcode: M25switch_pin: host:gpio20 V u?ivatelském rozhraní se nám to pak zobrazí nějak takto:Samoz?ejmě je nutné mít na paměti, ?e vstupy mají oto?enou logiku. To znamená, ?e v klidovém stavu jsou v LOG-1 a v momentě sepnutí p?ejdou do LOG-0. To je zp?sobeno pou?itím opto?len? na vstupech MCU. Nicméně logiku vyhodnocení je mo?no upravovat v konfigu p?idáním znaku vyk?i?níku (!) p?ed definici pinu: switch_pin: !host:gpio12. To by mělo jako ukázka pou?ití shieldu s firmwarem Klipper sta?it. Pro dal?í informace nav?tivte stránky s dokumentací pro tento firmware, kde se m??ete do?íst více podrobností, které se do tohoto zjednodu?eného návodu neve?li.https://www.klipper3d.org/Overview.html Pou?ití s Repetier serverem:Dal?í mo?ností je pou?ití s Repetier serverem. Zde je zprovoznění mnohem jednodu??í, ale na druhou stranu to neposkytuje tolik mo?ností jako Klipper. Av?ak pokud pou?íváte tento server, vy?aduje zprovoznění pouze definování pat?i?nych funkcí ve webovém rozhraní serveru. Opět pár informací je mo?no najít v diskusi ZDE v?etně video návodu na mém YT:https://youtu.be/qEGrFefesb4 Pou?ití s dal?ími servery:Samoz?ejmě toto není vy?et v?ech pou?itelnych server?.

Allows you to use a Raspberry Pi Zero to output a perfect digital image via HDMI. The pixel clock is derived in a very different way to other implementations which means no Denise / Super Denise jumper and no "sparkling" pixels.The newer v2.1 is designed to be easier to build and easier for the user to install, with the Pi facing the rear of the Amiga so that the HDMI can be plugged directly into it.For BOM and software / firmware setup details please see the README file here: https://github.com/LinuxJedi/AmigaRGBtoHDMI/tree/main/Amiga2000CPLDSlot

Couple of months ago, I bought a "Raspberry Pi Pico" to get some hands-on experience of it and to create some amazing projects using it. But since then, it has just been sitting on my desk, collecting dust. Today after a very long wait, I finally have decided to create a short video tutorial to show you guys how to get started with the Raspberry Pi Pico.Topics Covered In this tutorial, I am going to discuss:1. What is a Raspberry Pi Pico?2. The technical specifications of the board3. How to program Pico using C/C++ and MicroPython a. Programming Raspberry Pi Pico using "Arduino IDE" i. Preparing the Arduino IDE ii. Loading the Blink Example iii. Demo b. Programming Raspberry Pi Pico using "Tonny Python IDE" i. Installing MicroPython on Pico ii. Installing Tonny Python IDE iii. Loading the Blink Example iv. Demo4. Difference between Raspberry Pi Pico and Arduino5. Advantages and Disadvantages of this boardWhat is Raspberry Pi Pico?Raspberry Pi Pico is a low-cost microcontroller. It can be used to control other electronic modules and sensors same as any other microcontroller.Pico is not a Linux single board computer, rather it is a microcontroller like Arduino. Since, its a microcontroller it doesn't come with all the overheads that a computer brings and hence consumes much less current. actually it is more like Arduino than Raspberry Pi.Pico is not a rival of Raspberry Pi Zero, it actually can work in conjunction with the regular Pi's.Pico is breadboard friendly and has 40 GPIO pins operating at 3.3v (20 on each side). It has a Dual-Core ARM Cortex M0+ processor. Pico's brain - the RP2040 microcontroller chip is designed by Raspberry Pi in United Kingdom. It can be powered either via the micro USB port, or via the VSYS GPIO pin by providing voltage between the range of 1.8V to 5.5V.Technical Specifications of PicoRaspberry Pi Pico is absolutely different from all other Raspberry Pi models. Pico is one of the first microcontrollers to use the RP2040 "Pi Silicon" processor. It is a custom "System on Chip" (SoC) developed by the Raspberry Pi team in UK which features a dual core Arm Cortex M0+ processor running at 133 MHz, 264KB of SRAM and 2MB of flash memory for storing files on it. Specifications:- Microcontroller: RP2040 designed by Raspberry Pi in the UK- Processor: Dual-Core Arm Cortex-M0+ processor, flexible clock running up to 133 MHz- Input power: 1.8 - 5.5 V DC- Operating temperature: -20°C to +85°C- Dimensions: 51.0 x 21.0 mm - Onboard Sensors: Temperature Sensor- Memory: 264KB of on-chip internal SRAM and can support up to 16MB of off-chip Flash 2MB on-board QSPI Flash (Adafruit's Feather RP2040, features 16MB of storage)- GPIO: It has 40 GPIO through-hole pins also with edge castellation- 26 × multi-function 3.3V GPIO pins, which includes 3 analogue inputs (The Analog inputs is something other Raspberry Pi's lack. They use variable voltages to connect to devices like a potentiometers, joystick or a LDR) - 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels- 8 × Programmable I/O (PIO) state machines for custom peripheral support that can offload many kinds of timing-critical processes from the CPU - Other Features:- 1 × Contains 1 × USB 1.1 controller and PHY, with host and device support- Accurate clock and timer on-chip - Low-Power sleep and dormant modes- Accelerated integer and floating-point libraries on-chip- Works with Windows, Mac, Linux machines and Raspberry Pi Computers- Provides drag-and-drop programming using mass storage over USBThe one biggest disadvantage of the Raspberry Pi Pico is that there is no WiFi or Bluetooth on it. ESP32 and ESP8266 which you can buy for similar price comes with WiFi and Bluetooth (ESP32). Surely we can add wireless connectivity via external components, however that would require a little bit more knowledge and experience to get it working.Since Pico is not a computer, we need to write our codes on a different machine using an external application and then "flash" the code onto the microcontroller over USB.Pinout Diagram: Here is the top view of the pinouts on the Raspberry Pi Pico. The pin-labels are on the bottom side of the board.How to program Pico using C/C++ and MicroPythonPi Foundation officially supports MicroPython and C/C++, however high-level programming language like CircuitPython (A fork of MicroPython created by Adafruit), and Drag and Drop Python Editor like Pico Piper which adds further enhancements and can be used to program the Pico boards.Programming Raspberry Pi Pico using Arduino IDEPython and C/C++ are both great for programming Picos. However, being able to program a Pico just like an Arduino would help us to integrate the Pico into the Arduino ecosystem. One of the best reasons to do this is because of the availability of libraries to integration of modules, sensors, and other complex stuff without having to write the entire code from scratch.i. Preparing the Arduino IDETo start, let go to Tools > Boards > Boards Manager and search for "Pico", select "Arduino Mbed OS RP2040 Boards" and hit the install button.Connect the micro USB cable to the Pico and then press and hold the "BOOTSEL" button before plugging the USB cable into the computer. Release BOOTSEL once the drive RPI-RP2 appears on your computer.Now, go to Tools > Port and you will now be able to see the number of the COM Port.ii. Loading the Blink ExampleGo to Files > Examples > Basics > Blink and click on Upload, this will load the code to the Pico board.iii. DemoAfter the IDE finished uploading the code, you will see the Pico's onboard LED blinking.You can now use your Pico like an Arduino and program it using the Arduino IDE.Programming Raspberry Pi Pico using Tonny Python IDEYou can program your Pico using MicroPython by connecting it to a computer via USB and then dragging and dropping files to it.i. Installing MicroPython on PicoInstallation of MicroPython on Pico requires a "UF2" file to be copied onto it. A UF2 file is a "binary data file" which contains a program that can be transferred from a PC to a microcontroller, such as an Arduino or Pico circuit board. To load MicroPython on Pico:1. Download "MicroPython UF2 file" from the link provided in the description below.2. Connect the micro USB cable to the Pico and then press and hold the "BOOTSEL" button before plugging the USB cable into the computer. Release BOOTSEL once the drive RPI-RP2 appears on your computer.3. Drag and drop the UF2 file onto the RPI-RP2 volume. 4. Your Pico will reboot. That's it, you are now running MicroPython on your Pico.ii. Installing Tonny Python IDETo write code and save files to Pico we are going to use the "Thonny Python IDE". Thonny comes with built-in Python 3.7, so just one simple installer is what you need to learn programming. To get started:1. Download and install "Thonny" free from the Thonny website for your version of OS. The website's link is in the description below. Note: If you are running "Raspberry Pi OS" then Thonny is already installed on it, but may need to update it to the latest versionsudo apt update && sudo apt upgrade -y2. Connect the Raspberry Pi Pico to your computer. Then, in Thonny go to Tools > Options and click on the "Interpreter" tab. From the interpreter dropdown list select "MicroPython (Raspberry Pi Pico)". The port dropdown menu can be left to "automatically detect the Pico". Click "OK" to close. 3. A Python Shell called "REPL" (Read, Eval, Print, Loop) will popup to show that the Pico is connected and working.iii. Loading the Blink Example1. Click in the main editor pane of Thonny and enter the following code to toggle the onboard LED.from machine import Pin, Timerled = Pin(25, Pin.OUT)timer = Timer()def blink(timer):led.toggle() timer.init(freq=2.5, mode=Timer.PERIODIC, callback=blink)2. Click the "Run" button to execute the code. 3. Thonny will ask whether you want to save the file on "This computer" or the "MicroPython device". Choose "MicroPython device". Enter "blink.py" as the file name. Make sure you enter ".py" as the file extension so that Thonny recognizes it as a Python file. iv. DemoYou should now see the onboard LED switching between on and off until you click the Stop button.Difference between Raspberry Pi Pico and Arduino* Before Raspberry Pi Pico, Raspberry Pi has always been know for their single board computers. However, in 2021 Raspberry Pi Foundation stepped a few steps forward and launched the Raspberry Pi Pico giving a head-to-head challenge to Arduino and all other board based microcontrollers.* Arduino was first introduced in 2005 and since then Millions of Arduino Units have been sold in the market. Compared to that, the response Pico received after its initial launch in 2021 is absolutely mind-blowing.* Both units are made for automating applications that don’t involve human intervention. * Pico can be used alone or in combination with Arduino for Automation and AI purposes. * Both modules are different in terms of power consumption, value, functionality, and price.* Pico boards come unsoldered however Arduino comes pre-soldered or unsoldered.* Pico module supports MicroPython and C/C++, while Arduino codes are written in C/C++ using Arduino.IDE.So which one to go for… Pico or Arduino?Advantages and DisadvantagesNow lets have a look at the Pros and Cons of this microcontroller board.Advantages: * Raspberry Pi Pico is cheap, very small, and easy to use microcontroller * Pico is a dual core device coupled to a high-performance bus matrix, which means its both cores can give you the full performance concurrently * Pico consumes very low power * Pico is a breadboard friendly * Pico can be programmed using C/C++ and MicroPython * Pico can be programmed using Arduino IDE * Pico has 26 × multi-function 3.3V GPIO pins (23 Digital + 3 Analogue) * Pico comes with 8 x Programmable IO (PIO) and 2 x Analog Inputs * Pico boots quickly and doesn’t require a safe shutdownDisadvantages: * Pico completely lacks WiFi and Bluetooth without any add-ons * It lacks the GPIO markings on the top side of the board * The board comes unsoldered so you will have to solder the header pins or surface mount it to use it in your project * GPIO pins are 3.3V, which could be seen as a disadvantage, however devises designed for 5V can still be used with 3V via a voltage divider or a logic level converter. * Pico still uses micro-USB port. While many other microcontrollers have moved to USB-C, Pico is still coming with the micro-USB portIf you have a Windows, Apple, Linux or even a Raspberry Pi, then you are already well in your way to program the small, cute, and gorgeous Raspberry Pi Pico in your next project. I bet, there must be a lot of project ideas going in your mind, so get your supplies and start coding. And, what are you waiting for???ThanksThanks again for checking my post.
