A tiny external monitor for PC using STM32 and ST7789. Connects to PC over USB and displays the captured screen on ST7789 (240x240) display.
STM32 Tiny Monitor
A super tiny monitor for your PC, suitable for your pet ant.
A python script sends the captured screen over USB to the STM32 microcontroller, then that data is displayed on ST7789 display. FPS is not that high, but I made it good enough after several optimizations.
I made this project because I'm learning USB now and this is a fun project to practice USB stuffs. I still know almost nothing about USB. To get started, follow this tutorial: https://medium.com/@manuel.bl/usb-for-microcontrollers-part-1-basic-usb-concepts-519a33372cc9
Parts:
- STM32F103 MCU (Bluepill)
- ST7789 SPI Display (240x240 resolution)
How to use:
- Compile the firmware and flash the microcontroller
- Follow the instruction in host_python_scripts folder to run the host software.
- Connect microcontroller to PC using USB cable. Host software will start the stream.
- Enjoy your tiny monitor :)

TODO:
- Optimize the device (mcu) firmware. Buffer the incoming packets befoe sending to SPI bus.
- Write host software in C/C++ to get higher performance
Feel free to modify the code and do whatever you want with this useless project.
