This project started a long time ago, circa 2007; during that time, as serial and parallel interfaces had recently (almost) disappeared, electronics enthusiasts found very difficult to program microcontrollers; old time serial programmers didn't work any more.

Common solutions were USB to serial adapters or add-on interface chips; but this was essentially going around the problem and still using old school serial communications.

So why not using a native USB interface like the one present in some PIC microcontrollers?

After searching a while I couldn't find an USB programmer which was at the same time functional, free, and open source, so I decided to design one.

The focus is on PIC micros, but also many AVR are supported, as well as serial memories using different interfaces like I2C,SPI,MicroWire,OneWire,UNIO; altogether over 800 devices.
