STM32 BluePill controlled byThis is a baremetal firmware code for a STM32F103C8T6 "BluePill" development board. This firmware blinks an LED, and runs a JSON-RPC client/server over the UART. With this setup, this board can be wired to the https://vcon.io, which gives the following functionality:
- Allows to remotely flash the BluePill board
- Allows to call BluePill's functions over the network
- Allows BluePill to call VCON functions like MQTT publish/subcribe, create/edit/delete/download files, etc
Basically, VCON grants remote control capabilities without writing a single line of networking code, and grants Over-the-Air firmware update without writing a single line of code.
