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/src/stm32f4xx_it.c | 54 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 src/short-test/src/stm32f4xx_it.c (limited to 'src/short-test/src/stm32f4xx_it.c') diff --git a/src/short-test/src/stm32f4xx_it.c b/src/short-test/src/stm32f4xx_it.c new file mode 100644 index 0000000..b816d0d --- /dev/null +++ b/src/short-test/src/stm32f4xx_it.c @@ -0,0 +1,54 @@ +/** + ****************************************************************************** + * @file stm32f4xx_it.c + * @date 08/07/2015 17:45:59 + * @brief Interrupt Service Routines. + ****************************************************************************** + * + * COPYRIGHT(c) 2015 STMicroelectronics + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * 1.
