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 ...
