Insert usual disclaimer here about messing with mains!! It would obviously be very dangerous to plug this into a hot socket. My first thought would be to have the "transmitter" board send a very low bit rate unique pattern on the three pins. Simplest example would be just to do varying length pulses...

Thank you for this update about how i2c can be instantiated in the newer MicroPython versions. Is there a way to turn off the "Warning: I2C(-1,...)..." message that is sent to shell? I am using the hardware I2C pins of my device and the machine.I2C() instantiation accordingly. I don't want the user...

MicroPython v1.19.1-2-g8e3f8fb on PYBD-SF2W Also can't find this commit in the history... The following script might reproduce the problem, perhaps increase the number of files to create. No exception is reported when flash boundary is exceeded. I'm not sure I understand how to run this script. Her...

MicroPython v1.19.1-1-g093d292 I can't find this commit in the history... Where did you download this from? What's the full .dfu filename? When i use the code you mentioned an exception is raised saying 'unknown config param'. It has something to do with the security parameter. Maybe it was added a...

Which board are you using? You're posting in Pyboard-D but "authmode" has never been a supported config argument for the Pyboard-D as far as I can tell, only on ESP32 and ESP8266. On Pyboard-D the config argument is "security". I can confirm the following code works for me on ESP32 & ESP8266 on 1.19...

I tried to google search for "Rp2040 Lite purple 16M" but didn't see any obvious result.

You could probably just run the "Pico LiPo (16MiB)" firmware from the downloads page and it will work fine and use all the flash.

I am using MicroPython v1.12 on an ESP32 WROOM32 module. Very unlikely that this is the cause, but that is several major releases ago. I had been running a script without problems, but suddenly I got a consistent 'TypeError: can’t convert ‘float’ object to str implicitly’ error. What changed betwee...

A REST API is a protocol that works over HTTP and uses JSON to format messages. You can use it from any language that supports HTTP and JSON (including micropython).

MicroPython does not make the libc file methods available. If you want to access the filesystem you need to do it through MicroPython's VFS layer. See extmod/vfs.h

I've successfully compiled Micropython for the Pico W so I have things set up right. How do I do the compile flag to use the drivers/cyw43 version so I can set the hostname? It might not compile yet but I'd like to try. This isn't supported yet. Making this work that way isn't worth the trouble. In...
