Examples for LCD on T-Display S3? #31

Open clydebarrow opened 1 year ago

clydebarrow commented 1 year ago

I've built the Micropython binary and flashed it to a T-Display S3. I can run simple programs, but have no idea where to start to drive the LCD. I see there is an lcd module available, but have no idea how to use it.

Are there any examples for this (or something equivalent?)

Have the same issue here. The lcd module can't be used to display data, just for basic screen tests. You can find an example of "usage" here - https://github.com/Xinyuan-LilyGO/lilygo-micropython/blob/master/target/esp32s3/boards/LILYGO_T-DisplayS3/modules/inisetup.py

It looks like we need to use st7789, which should be included in the firmware, but it's not for some reason, or I can't find it.

Digging into this more, russhughes/st7789_mpy does not get compiled it, it gets downloaded, but never included in the build process. only the LCD module is. There are examples of using it with a framebuffer, Check out the build_dir/esp32s3/lcd_binding_micropython/examples for some examples of using the LCD lib

Here are some examples, it should all work.

@jetbalsa Currently russhughes/st7789_mpy is only used on T-PicoC3.
