in repository user/ft/stm32-dev-bridge.
commit 8af6e5c4d9764afb89395ccc006674277a859024
Author: Fredrik Thulin <fredrik at thulin.net>
Date: Thu Sep 10 10:51:57 2015 +0200
Add application useful in helping identifying electrical shorts.
This application tries to help finding elecrical shorts in the dev-bridge
board by configuring all pins but one at a time as input (pull-down), and
then outputing a bit to one pin and checking that none of the input pins
go high.

+go high.
+
+Usage:
+
+Flash it
+picocom -b 115200 /dev/ttyUSB0
+
+You should see nothing but line feeds in the terminal emulator.
+
+Red LED should stay OFF.
+
+Blue and green LED should toggle (in tandem).
