Re: Support for a SPI TFT 2.4'' screen
I pushed another update, hopefully it will solve the issue. It supports 16bit (5-6-5) channel. But still puzzled why on datasheet it mentioned 18bit for LCD.

Re: Support for a SPI TFT 2.4'' screen
Shahin, now the framebuffer works properly
See:
But still there's an issue when printing process starts and when using /dev/fb1 or /dev/fb0. Printing is stops after displaying first slice. It's only a fast blink, then screen goes black. I've no idea why... I must add, the picture that blinks seems to be correct.
See:

Re: Support for a SPI TFT 2.4'' screen
Marvelous.
Now the printing process goes smooth. (nanoDLP build 1725)
I'll prepare informations how to connect and use SPI TFTs with your software and will put them somewhere here. It should be useful for other makers, I think.
Thank you for your time and effort. Good job!
