Small board running a couple of always on services. Roughly every four months the card corrupts and I reflash it, restore my config and carry on. I have tried a better brand of card, which did not obviously help. It…
I plugged in a development board and the IDE has no port to offer me. The port dropdown is empty, or it lists only ports that were there before I plugged anything in. The board's power LED comes on, so it is getting…
I have a simple sketch generating PWM on an ESP32 that compiled fine before. On a fresh install of the IDE and the current board package, it fails at compile time saying the LEDC setup function was not declared in this…
I am trying to program a microcontroller board over USB and the upload fails saying it could not connect, or that no serial data was received. Sometimes the port does not appear in the list at all, sometimes it appears…
New board, and the first thing I tried was blinking the onboard LED. Nothing happens. The pin toggles as far as I can tell, I added serial output and the loop is definitely running, but the LED never lights. The board…
I bought an inexpensive sensor module, wired it according to a tutorial, loaded example code from the library everyone recommends, and it returns nothing. No error, just no readings. I have re checked the wiring against…
Working on a microcontroller project, the editor reports that include errors were detected and asks me to update the include path. Every library header is underlined and autocomplete does not work. The confusing part is…
I want to read the debug output my board prints, and to send it the occasional command. The editor I use has a built in serial monitor, and I have also seen people use a standalone terminal program. My attempts produce…
Budget is about 200 for everything including storage. It lives on a bookshelf in the living room so noise matters, and it needs to be on all the time. Usually one stream direct playing to a TV, occasionally a second…
It sits on a shelf indoors, writes clips to a USB stick and I have honestly not logged in for over a year. Now I am wondering whether to preemptively replace it before it fails at a bad time, or leave it alone on the…
It runs a camera timelapse script and I only reach it over SSH. It stays reachable for three to six hours, then vanishes: ping fails, the mDNS name is gone, nothing. The script keeps writing image files the entire time,…
The door has to open at sunrise and close after dusk whether or not anything else works, and I want to see the shed temperature on my phone from the house. Wifi reaches the shed but it is marginal, and we lose mains…
I have the boards, three 5V supplies and a couple of cards, and no budget to buy a Pi 5 just to have something to do. I would like something actually useful rather than a demo I look at twice, and it needs to sit on a…
Third card in five months. It runs fine for two or three weeks, then DNS stops resolving and I find the root filesystem remounted read only. Two of the dead cards were 32GB Samsung Evo Select, one was a no name from a…
I get the lightning bolt in the corner every time the drive spins up, and returns 0x50005. The drive is a 2.5 inch spinning laptop disk in a plastic USB3 enclosure, bus powered, and it is the only thing attached apart…
First Pi, first project, so I have no baseline. It is in one of those aluminium cases where the whole shell is the heatsink, sitting on a desk in a room that is about 22C. Idle with nothing running it reports 59 to 61C.…
