STM32 BluePill controlled by https://vcon.io

This is a baremetal firmware code for a STM32F103C8T6 "BluePill" development board. This firmware blinks an LED, and lets user change blink interval via UART - by entering numbers from 0 to 9.

This is a demonstration firmware for the VCON framework which implements OTA firmware updates and remote control. See https://vcon.io/docs for details.

Build

Install gcc-arm-none-eabi cross compiler on your system, then run:

make

That produces bluepill.hex file, suitable for remote firmware update via VCON.
