A simple tool to reset a Maple STM32F103 (aka 'BluePill') board on Windows
Maple boards are ultra-cheap compact devices based on the STM32F103 chip. They need a specific sequence sent on the serial port in order to enter DFU mode. The sequence is DTR going from true to false, followed by the string 1EAF being sent.
The program does exactly that - toggles DTR and sends 1EAF, putting the board into DFU mode for programming.
