Display not showing the correct windows while running this example #332

Open TheElectronicMusicProject opened 1 year ago

TheElectronicMusicProject commented 1 year ago

I'm using a 1.8TFT SPI 128x160 display. I also use develop/lvgl_7.11.0_idf_5.0 for lvgl_esp32_drivers and v7.11.0 for lvgl.

Describe the issue I use the following connections:

Running the example I don't see the correct result on the screen.

Code to reproduce the issue The given example with the following sdkconfig where I matched the pins and the display resolution

Expected Results The windows shown in the example

Actual Results I see this picture on the screen with fluctuations of the content but it doesn't work. photo_2023-04-24_17-27-11 In the serial monitor I don't notice anything "strange":

Compilation warnings/errors (if available) Yes, some warnings at the bottom of the log. lvgl_log_build.txt

If possible, copy the compilation log into a file and attach it here

1) Is this display supported? 2) If yes, what kind of error I'm encountering? 3) Is there a way to fix it?

Thank you for your help

Your Display looks like mine does if I try to put the SPI frequency too high. Try backing it off.

@CE3kmacriver I posted this issue here, they said I should use another driver for this display. I looked for the ST7735S but it gives errors while compiling..
