#pipico2w — Public Fediverse posts

dear fedi, please help

I have my 2 keyboard halves of the beekeeb piantor (non pro) which are just wiring the mechanical switches to the gpios, no matrix

i'm migrating from pi pico to rp2350b-plus-w by waveshare (custom rust firmware which I'm developing)

the board is a breakout board essentially and has a voltage divider for vsense to gp42. that's it

NOW

the left half, is completely fine

the right half though has gone through the following:

- after many flashes, the MCU started looping like crazy on USB, even on boot mode. Enumerated, showed up and insta reboot. probably toast - maybe I did something stupid in the wiring/soldering, no biggie, I have 3 spares

- next spare, all goes good but 1 key starts sticking. it doesnt work when I press it and at some point it gets stuck. all gpios are internally pulled up. I measure it and it gets pulled to around 1.5v. probably toast gpio, no biggie, I have 2 spares

- before I replace the MCU, I grab a new one, flash it and measure all pins and ALL of them get pulled to 3v3, as expected. I put the board on the right half, some time passes, 1 gpio fails and a bit later, another one fails

what the heck is happening??

obligatory AIed and googled to death. I found out about the errata 9 of the 2350 but its not relevant, it has to do with pull downs, not pull ups

Also this article https://randomnerdtutorials.com/raspberry-pi-pico-w-bluetooth-low-energy-micropython/ another potential option for getting the data from our #Bluetooth batteries using #micropython on a #pipico2w
They have what looks a good book too https://randomnerdtutorials.com/raspberry-pi-pico-w-micropython-ebook/

I found a nice way to interact with the S0 counting bus of my three energy meters. Every single used GPIO pin gets it's own interrupt for measuring the time in between last 1->0 change. Every 15 seconds a mqtt broadcast is done to report the average consumption. In addition a one hour and 24 hour sum array is filled too. So no need for PIO operations any more.
