Glad you like it. Yes, I have quite a few RP2040s, and Picos. I’m probably going to switch over to using them instead of the STM32F103 blue pills and ICs I have use din the past. Partly because of the supply problems and partly because the RP2040 is so much more capable. And they are cheap, the ICs probably less than an equivalent STM32, and the Pico around the same as a blue pill.
I was thinking about a multiple Pico computer this morning. There’s quite a lot of extra components needed for an RP2040, not least of which is external flash, so I am wondering about just stacking Picos. They are castellated so wouldn’t necessarily need aPCB, just run wires down the sides of the boards. I’m not sure using the ICs would be much smaller or cheaper once the extra componentry is added.
I’ll be setting the github to public, yes. The code is a bit untidy at the moment so I’ll tidy up and open it up. If anyone’s desperate I could put that towards the top of my list. If no-one asks for a project then I leave the github stuff until I have spare time.
