Arduino ST7735 LCD .bmp picture from SD card
15/05/2021 | by: ELECTRONOOBS      
Drawing bitmap images (.BMP format) on ST7735 TFT display is quite easy because they are uncompressed images unlike JPEG images (.JPG format). This post shows how to draw bitmap images on the ST7735 TFT using Arduino UNO board where the Arduino loads the BMP images from SD card and print them on the display. The ST7735 TFT is a color display that uses SPI protocol, it has a resolution of 128×160 pixel. This display works with 3.3V only.
