“This post describes Mesa-Video, a low cost, low power, small size and fully Open Source Hardware and Software solution for providing 800×600 digital video for Arduino ( and other ) microcontrollers. Mesa-Video makes it quick and easy to display text and 24bit color graphics from any MCU using a single UART serial port pin. Applications for Mesa-Video are embedded projects requiring video output and embedded developers wanting real time visibility into their system operation. Mesa-Video is the 1st of multiple Mesa-Modules planned. For a quick summary of Mesa-Video and Mesa-Bus, please read the very nice article at Hackaday by Richard Baguley from 09_01_2015.”
