Use of an KMR-1.8 SPI 128*180 TFT #113

Hi Edzelf, what a phantastic project, thanks at first. Based on your documentation I've bought a KMR-1.8 SPI 128*180 TFT, pic was (nearly) identical to this in your ESP32-radio.pdf. But it won't work (backlight is on, but only white screen), checked all connections repeated. Configuration is as standard from your .ino:

define BLUETFT is enabled, others are disabled

Additional Adafruit GFX and ST7735 libraries are installed, sketch compiles without problems.

I've seen (here: [https://forum.arduino.cc/index.php?topic=406501.0]) that this TFT needs other drivers. Is it possible to use it with ESP32-Radio? How?

Thanks! Nils

I hope your display is 128x160, not 180. Try to find out what diver works. Then I can write an include file for this display.

Rebewslin commented 6 years ago

Hello Edzelf, Yes, it is 128x160. That was a Typo, sorry. Additional reading of the thread I linked above shows me that there are a lot of different „KMR-1.8 SPI“ displays with several driver ic. I‘ve no possibility to check it out, which one is built inside my display. I will ask my eBay seller and come back with the answer.

Which display is yours and where exactly can I buy this model? Nils

I have added links to the supported displays in the documentation. You have to download the PDF file to make it work.

Hello, I use the same display, mine has an ST7735 chip. I have been able to make it work by using the "TFT_eSPI" library which is available on GitHub. Mine needs the ST7735_REDTAB enable. I had to make some modifications of the original radio software to make it work correctly. I haven't been able to make the SD working yet.

Thanks for your informations! @fred451 : Would you like to share your modifications? How has you included the TFT_eSPI Library?

The library (Link to Github) seems interesting, optimized for ESP32, fast and Support for different display-drivers …

That's ok for me, but the way I did it is not very elegant, well anyway you'll find my modifications in the attached document.

You might have to make some more modifications as I did remove some parts of the original software which were not necessary for my needs.
