From 8af6e5c4d9764afb89395ccc006674277a859024 Mon Sep 17 00:00:00 2001 From: Fredrik Thulin Date: Thu, 10 Sep 2015 10:51:57 +0200 Subject: 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. --- src/short-test/README | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 src/short-test/README (limited to 'src/short-test/README') diff --git a/src/short-test/README b/src/short-test/README new file mode 100644 index 0000000..a001eec --- /dev/null +++ b/src/short-test/README @@ -0,0 +1,15 @@ +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. + +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). -- cgit v1.2.3
