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.
First part of this project for a homemade DLP resin printer based on Arduino, transparent LCD mask, UV light and stepper motor control. This part we make only the electronics and code. Next part is mechanical.
Another cool project with the WatchX development board. Check their new design and mount this project for controlling a Tello drone using the on board IMU and Bluetooth + WiFi connection. See links below.
