Support for Waveshare ESP32-S3 1.43inch AMOLED Display

[cddmp]

Hi,

first of all thank you for all your work you put into this. Looks great to me! Withoug digging too much into the code, how difficult would it be to add this display: https://www.waveshare.com/esp32-s3-touch-amoled-1.43.htm

Edit: Use case would be primarily navigation.

seems the configuration is almost similar to the Viewe boards https://github.com/fbiego/esp32-c3-mini/blob/07e8b48f353db3f37ad4a3cfb202aab5a4af1682/platformio.ini#L18

Can you try it? You may need to change pinout https://github.com/fbiego/esp32-c3-mini/blob/07e8b48f353db3f37ad4a3cfb202aab5a4af1682/hal/esp32/displays/pins.h#L169-L184

Thanks for your reply, I really appreciate that!

I actually thought the same and tried the Viewe configuration yesterday. The building and flashing worked, but the display did not work.

I found this project which does a similar thing than you, but limited to Navigation: https://dhruv-pandey93.medium.com/turn-by-turn-navigation-on-small-displays-9ea171474095 https://github.com/pdhruv93/minimal-nav/tree/main He uses the ESP32-S3 1.43 inch Amoled display. The code includes a driver for the SH8601 (Amoled driver IC) and the FT3168 (touch controller), while the Viewe seems to use the CO5300 as well as the CST9217.

Now, what confuses me is, that Waveshare actually lists both display ICs. Seems they have different batches:

I do some research and come back to you.

I see this display has an enable pin. Can you add the line below and try? #define LCD_EN 42

According to https://www.waveshare.com/esp32-s3-touch-amoled-1.43.htm I configured the display pins like that:

When I reset the device it shows the ESP32 C3 Mini "Welcome" screen as well as date and weather afterwards. The display then turns off. This is how it looks like. Seems like the size does not fit?

Here is the serial log output. The touch driver is obvioiusly the wrong one.

Awesome, now that the display works next thing is to configure the touch driver. The display turns off after x seconds because its a setting in the UI, it's a feature and can be set to Always On

I will have a look at the touch driver.

Edit: It seems as if sensorlib does not support the FT3168/FT6146. I could take the code provided by Waveshare for those controllers and check if I can integrate them into your code. Though the cleanest option might be to add it to sensorlib.

I have a working proof of concept. I will report back.
