Oh yeah, completely agree!! Definitely go with the ESP32 (or Pyboard D, if you're using DotStars). Most of my experience with this was before before the ESP32 was widely available.

Also I'm a really big believer in the sunk cost fallacy and have a drawer full of ESP8266s :p

Does your code write to the filesystem during normal operation? Was there possibly a power outage (or if it's battery powered, a low battery state) that coincides with the corruption?

I don't understand the initialization sequence. The external reset is low, then high, then low? Or the other way around? For how long? This is a fairly typical "active low" reset line. You can use it from software to force the device into a known state. The RST line is "active low" which means it w...

In addition to the ESP32, the ESP8266 and micro:bit have built-in neopixel drivers. I strongly prefer DotStars leds instead (APA102) because they don't require a driver, as long as your board supports SPI you can use them. (Which is every board). Also you can transmit data to them at a higher rate (...

If the filesystem isn't suitable, then you might find this uesful

Hi, Sorry I don't have a great answer to your main question. The topic of ensuring that the WiFi stays connected has been discussed a bit in the forum before, but I think it remains a bit of a tricky problem. I haven't looked in any detail myself though. One thing that might be worth checking out is...

Possibly https://github.com/JanBednarik/micropython-ws2812 or https://github.com/nickovs/ws2812-SPI Both of these generate the WS2812 data signal using SPI (by oversampling each bit into several SPI bits). If you feel like building your own firmware, I have a neopixel driver written in C for pyboard...

I already tried to get rid of the many USB references within the source files ... I'm unsure why you had to remove any references other than in mpconfigboard.h (I assume you already set MICROPY_HW_ENABLE_USB to zero (in addition to MICROPY_HW_USB_FS), which should cover everything). I started from ...

If this was working before (like a few months ago) then you possibly had pyusb installed for python2, but now the MicroPython makefiles use python3 by default.

Sounds like you need to install pyusb?
