Tasmota_display: is there support for esp32c3 + oled display?

[dattasaurabh82]

I was just thinking about purchasing ESP32 C3 with 0.42" SSD1306 i2c OLED mcu+display board.

But from the webflasher esp32 bin file says it's not compatible for esp32c3 and also after flashing tasmota32-display.bin using esptool.py I get loading from mem issue.

Flashing cmd I used:

esptool.py --chip esp32c3 --port /dev/tty.usbmodem1131101 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size 4MB 0x0 tasmota32-display.bin --force 

Note: (I used --force as it was complaining that it wasn't compiled for c3)

I then found tasmota/displaydesc/SSD1306_70x42_display.ini

So, does that means esp32c3 is supported in tasmota_display bin?

Any leads from here?

Well what's not supported is to use a binary for the wrong ESP32 architecture. ESP32-C3 is a very different chip from the older ESP32, meaning that you need builds where the image file name starts with tasmota32c3 instead of just tasmota32. Using "force" means that you are asking for it to fail for the wrong architecture, instead of telling you that it was wrong.

In general, you should create a custom build for mixes of features and architecture outside of the precompiled binaries, but there are some "unofficial" development builds, including for tasmota32c3-lvgl having display support, not just for LVGL/HASPmota.

And after flashing, you should indeed configure for the display, including a display descriptor file.
