STM32F103C8T6 USBSerial Demo

This project contains demo of the USB serial usage for a cheap developer board Blue Pill with STM32F103C8T6 mcu.

The USB serial port provides a good communication channel between PC and microcontroller. Especially it can be useful for a debug purposes.

Notes

  • by the specifications this board has only 64KB of the flash, but actually it can have 128KB, that will be useful for a debug builds as it requires about 100KB of the flash for this demo.
  • the board can have some problems with an USB because it has wrong value of the pull-up resistor
  • for steady reading of data from a serial port, the project contains python script serial_reader.py (it requires PySerial and six python libraries), that is steady to the board reloading
  • the project depends on the fork of the USBDevice library. This fork contains some fixes and support of the BLUE_PILL_STM32F103C8 target.
  • the mbed-os now contains correct code for a clock initialization of the BLUE_PILL_STM32F103C8 target, so you don't need to adjust the board clocks separately

Initial release

The project contains autogenerated makefile for a debug build,
the program itself (main.cpp) and the helper python script
'serial_reader.py' to read a data from a serial port.
