Re: [Errno 112] EADDRINUSE

Try adding: s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) before bind(). Explained here: https://stackoverflow.com/questions/3229860/what-is-the-meaning-of-so-reuseaddr-setsockopt-option-linux I don't know for sure if that's your problem, but it sounds like it is based on the condition eve...

Re: [Errno 112] EADDRINUSE

It would be best if you posted the code your running. You probably are not deiniting the server/socket properly. Socket might still be hanging around somewhere.

Re: Binary differences for ESP32 on this site.

idf4 is the version of the esp-idf that the firmware uses. previously 4 wasn't supported, and now it is, so I assume that is to mark the epoch for esp-idf 4 in 1.14 versions where the transition from 3.3 to 4 occurred. 1.15 uses esp-idf 4+ only, so no need to identify esp-idf versions in 1.15 microp...

Re: Can't include USER_C_MODULES since v1.15 ?

Try passing the absolute path instead of a relative one. I think the base directory changed, so the same relative paths won't work. I don't know if they are one level up or down, but using the full path will work.

Re: Eink Photo Display Problems

I was under the impression that an eink display had to be refreshed all at once? There are two completely separate operations. 1. Transfer image data to the display's internal buffers. that requires sending the "I'm sending you display data" command. 2. Tell the display to transfer the internal buf...

Re: Eink Photo Display Problems

load it in chunks instead of in one go. e.g in pseudocode spi.write(START_DATA) with open('image.bmp', 'r') as f: while bytes_left_in(f): spi.write(f.read(1)) # read one byte and send it over spi spi.write(END_DATA) spi.write(DISPLAY) It's more complicated than that but that's the general idea, im n...

Re: ESP32 lvgl remonte gui : question

comment on the video and ask?

there's a micropython-lvgl port out there:

No idea about the rest of the interface. Probably just grabbing the relevant data and sending it over a websocket.
