Sneak preview JAL ST7789 library

[rob...@hotmail.com]

Hi all,

Some time ago I ordered 2 small color LCD's using an ST7789 and an ST7735.

The ST7789 module is 240x240 pixels and is 1,54 Inch, the ST7735 is 128x160 pixels and is 1,8 inch (do not know why they used a small display for a controller with higher resolution).

I am still in the testing phase of the ST7789 and need to start the debugging for the ST7735 but today I managed to show some pictures that are stored on an SD Card (thanks Matt for making the FAT32 and SD Card JAL libraries) on the ST7789. 

I used some pictures that I made myself and cropped them to 240x240 pixels. If all work is done I will store the pictures and the sample program in the project folder. There will also be a standard sample program without pictures but showing the graphics capabilities.

Fore a short demo see: https://youtube.com/shorts/vA7rM0_piqs

Since I am not yet done it will not be in the Jallib release but in one of the later bee-packages.

Kind regards,

Rob
