esp32 + ST7735

Post by scm »

Hello, I just updated my esp32 to annex v2.00.6 ,but now the attached ST7735 TFT display does not work. I downgraded to annex v1.70.52 and the display resumed working, was there a change pertaining to the ST7735 display?
Thanks

Good morning

The new version has changes regarding the graphics system.
I learned that there are some more options at the config page because of this now.
Did you check that?

Good luck!

Thanks for replying. I double checked the config , tried different settings,but nothing has changed. I switched the TFT display to an ILI9341 and set the config to match and that works just fine, so it seems I'll have to use the older firmware for the ST7735 display.
Thanks

Hi,
Since I changed the graphics library, it’s very possible that the ST7735 is not correctly configured, as it’s the only TFT I haven’t tested. (I should have some of them, but I haven’t been able to find where they are.) :roll:

Could you let me know the TFT configuration you’re using with the old release?
I can double-check and fix this in the next release.

Thank you for looking into it. The config TFT display is set to ST7735#2. I've also tried ST7735#0 to #7,with no change.

Thank you.

You should try the version 2.00.7; I included the driver for this display.

Good morning, the 2.00.7 version works very well on ST7735 128x60 with config set to ST7735#6 and on ST7735 128x128 with config set to ST7735#0.
Thank you very much for fixing this.
