Building a Rust Driver for PineTime’s Touch Controller

Pretend you’re my IoT student. I give you a PineTime Smart Watch and challenge you to “Make it work… Especially the touch screen!” The Touch Screen appears to be lacking some documentation. What would you do?PineTime Touch Screen = Touch Panel + Display PanelWe carefully pry open the PineTime Smart Watch with tweezers (or forceps) and examine the Touch Screen. It looks like a single chunk of plastic… But it’s actually two delicate pieces fused together: Touch Panel and Display Panel…PineTime Tou...

30V-4A Adjustable Power Supply (CC-CV)

By Hesam Moshiri, Anson BaoPower supplies are one of the most popular topics in electronics. There are two major types of regulated power supply: linear and switching. Both power supply types introduce some advantages and disadvantages, however, a linear power supply offers better line and load regulation figures and it handles lower noise at the output, specifically when the power supply is adjustable and the output is under load; although its efficiency is lower than a switching power supply. ...

Why Some PCBs Need Edge Plating?

Some people may have seen many industrial pcb boards or RF pcb boards with a circle of vias and copper tape around them, and even some RF pcb boards will be metalized around the sides of the board. What is the purpose of the edge plating?As the system rate of each product increases, not only the timing of high-speed digital signals, signal integrity issues are particularly prominent, but also the electromagnetic interference caused by the system from medium-high-speed digital signals and EMC iss...
