Continuing with the previous post, I’m sharing the black and white converter for the Adafruit 1.44″ TFT. This program converts any .PNG image into a constant char array that can be included and shown directly on screen. This program and accompanying code shows monochrome bitmaps (custom foreground and background colors) on the ST7735R driver. It was tested on a green tab TFT and is substantially much faster than the stock bitmap drawing routines.
This little project came out of the necessity for a program that could be used to generate embedded images for use in Adafruit TFT screens. This program converts any .PNG image into a constant char array that can be included and shown directly on screen. This program and accompanying code can show either packed color RGB 565 or monochrome bitmaps (custom foreground and background colors) on the ST7735R driver. These were tested on a 1.44″ Color TFT LCD Display and are substantially much faster than the stock bitmap drawing routines.
