Problem with LCD 128x160 ST7735S

[MSzła.1]

Hi, have any of you communicated with a display based on the ST7735S controller?

Based on this library: https://github.com/afiskon/stm32-st7735  I converted it from SPI communication to 8080 parallel control, but display does not work properly, while filling the screen with color works, writing text,  drawing pixels or squares does not, everything is visible in the video in attachment.

Below link to my project:

Thanks for help.

Hi,

Yes, I'm using the small TFT, but with SPI connection.

Why you don't use it with SPI?

I can't use SPI because the PCB is from an ebike computer. Exactly from the photo. They use the 8080 parallel interface to communicate with LCD

Ok, but on the video it's working, just some error in writing seems to be there, maybe you should try to make the timing more relaxed/slower, seems to be a timing/access problem.
