Display issues on the TTGO T-watch S76G (GPS + LoRa version)

Post by bhav » Wed Jun 22, 2022 4:50 pm

The TTGO website says they support MicroPython on their T-watch devices, but the documentation is awful. Regardless, I was able to find some great git repos by people who have done the device bringup. I am using https://gitlab.com/mooond/t-watch2020-e ... ree/master by Franz Schaefer.

Has anyone tried this on the S76G version of the T-watch? I can't get the display to work :( Other modules work fine, e.g. power management chip, backlight, touch controller, etc

The T-watch S76G looks close enough to the T-watch 2020 that the firmware and examples from https://github.com/russhughes/st7789_mpy should work, You may need to add additional modules to use other features of the watch.

Thank you! After flashing the firmware binary and pulling in the appropriate tft_config.py file for my device, the screen now works :D
