大家好久不见，2022年开始了，大家有没有设定今年要完成的小目标呢？ 2022年寒假在家一起练于2022年2月27日截止了，看到同学们提交的项目后，老师们倍感欣慰。同学们的项目都非常优秀，你们抓住了寒假的时光，为2021年的自己画了一个句号，给2022年的自己 ...

Raspberry Pi’s microcontroller, the RP2040, has some unusual features. And one of these is the i-o state machine, of which there are eight. spread over two ‘PIO blocks’ – (one shown right). According ...

I was lucky enough to get one minuscule microcontroller board, the RP2040-Zero from Waveshare. This is a low-cost, high-performance, RPi Pico-like microcontroller board based on the Raspberry Pi ...

Over the years, we’ve seen some modern microcontrollers turn out to be 5V-tolerant – now, RP2040 joins the crowd. Half a year ago, when we covered an ISA card based on a Pi Pico, [Eben Upton] left a ...
