Loading code into the SyncDongle

 SYNCDONGLE BLUE PILL STM-32 CODE LOADED OVER JTAG

I wired up the ST-Link adapter to the JTAG connector on the Blue Pill board. JTAG is a programming interface useful for loading flash memory contents or initializing processors and FPGA hardware. The ST-Link adapter plugged into my laptop through a USB port.

The code written by Mattis Lind is a mix of Arduino mainline code and some C library functions. I set up the Arduino development environment to handle the ARM cores on the Blue Pill, compiled everything and loaded it over the ST-Link to the SyncDongle board. It was now ready for use, once I provided power to the board and connected its two serial connections to the 3174 and a USB serial cable respectively.
