/**
|
|
* Sensor Watch Firmware Flasher
|
|
*
|
|
* This sketch is meant to run on an Adafruit PyRuler or Trinket.
|
|
* Connect the SWD, SWC and RST pads on the watch to pins 0, 1 and 3.
|
|
* Connect V+ on the watch to 3V, and GND to GND.
|
|
* This will power the watch from the Trinket so you don't need to plug the watch in to USB.
|
|
* Hit reset on the PyRuler / Trinket to begin the flashing process.
|
|
* The Trinket's red LED will blink slowly when the bootloader has been successfully written.
