=== Uploading Code to Blue Pill Using Serial Port ===

* FTDI connection to Blue Pill Hub FTDI connector
** FTDI TX (to Blue Pill RX) (PA10 pin on STM32)
** FTDI RX (to Blue Pill Tx) (PA9 pin on STM32)
* Set Switch (or jumper) on Blue Pill module set towards center of card to upload card to board

* In Arduino IDE,
** Tools
*** Board "Generic..."
*** Upload method: "Serial..."
*** Port: [the comm port]
