Simple hardware terminal emulator/display for debugging booting issues
Maybe this is not strictly related to Orange Pi PC but a few weeks ago I had problems with booting my device - mainly OpenELEC and I had to debug it somehow using serial port and the terminal. Unfortunately my PC is rather far from the place where I keep OPiPC. So I was forced to prepare separate device - cheap STM32 MCU based terminal display with 2.2" LCD screen directly supplied from Orange Pi PC 3.3V. It can be used also with other devices which allow serial console debugging.Watch below videos for more details and the code:
