Has anyone successfully made the esp32se sense work with the Waveshare 2 inch LCD module or maybe any ST7789 display?? i posted some days ago about the problems I was having getting the XIAO esp32s3 working with the Waveshare 2 inch LCD Module;

I did finally get it working (kinda) but I still have a problem making it work correctly. I’m using Bodner’s tft_espi drivers from github. The LCD is 240x320 (defaulting to portrait). No matter what I do, all I can use of the screen is 240x240 pixels. I tried multiple combinations of 240x320, 320x240, and set_rotation. The set_rotation works in that it will change the format of the 240x240 box as verified from text printed to the screen. Theres a pic of the the setup to help with the explanation below. The setup does work well with the espc3 in the picture with the same sketch and drivers with just a single jumper connection changed so I know the LCD works.

My best guess is that there is just something strange going on with the s3/driver combination. In a lot of posts I see, the s3 is still not fully supported in a lot of areas and when it is, its usually the dev board that has pins that the XIAO s3 doesn’t have. (Not knocking the s3, just the way it is)

Hello! After see your description, we have test our board with the screen which driven by st7789, we found it is well, so we think maybe there need some edit for the library file you include.

Thanks for the effort but could you pass on a little more information? As;
Did you have to change/modify any of the library files?
Are you using the Waveshare board or another 7789 board?
What is your wiring setup? Is it like the one I posted?
Can you include your test sketch. Are there changes from the one I posted?

Problems with esp32s3 sense with spi st7789 display

I can’t get my Kedei 2 inch LCD spi display to work with my esp32s3 sense. The display works great with my xiao esp32c3. Using the same pin out and sketch, I get nothing on the s3. I’m using the Bodmer’s tft_espi library from git hub for this project. I posted this same question on their discussion page with no responses. I’m hoping for some help here. My test code is below; It’s pretty simple. I’m just setting the color on the display. The defines at the end are for the pins that I’m u…
