Color terminal display based on STM32 and 2.2“ 320x240 LCD for Orange Pi PC and Raspberry Pi devices

This is my simple terminal emulator device which I constructed a few weeks ago mainly for debugging OpenELEC OS booting issues on Orange Pi PC SBC. I could just connect PC with terminal software but it wasn’t very convenient because my OPiPC is used far from PC. This simple HW solution can be used permanently with any device allowing serial debugging. Features and BoM: - all code created in Arduino IDE - ridiculously cheap $2 generic STM32 board - cheap ILI9341 2.2“ LCD with decent 320x240 resolution - 6x8 pixels font allows for 40x40 characters display in vertical orientation - display library optimized for STM32 capabilities, ILI9341 vertical hardware scrolling feature used - basic set of ANSI escape codes implemented (bold, font colour codes, etc) Code is available here:
