[Arm-netbook] STM32F blinky lights

[luke.leighton]

well amazing i am so happy to have managed to make an LED flash on the
little waveshare STM32F103RCT6.  it is such an achievement.  no,
really: a blinking light means a working compiler, working upload
mechanism over the serial port (stm32sprog), and picking the correct
GPIO location to make the flashy-blinkey thing go wiggle, wiggle.

from here it is easy to take over the world mwahahah, one LED at a
time.  might take a while, hmmm...
