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_hal_msp.c | 77 ++++++++++++++++++++++++++++++++++ 1 file changed, 77 insertions(+) create mode 100644 src/short-test/src/stm32f4xx_hal_msp.c (limited to 'src/short-test/src/stm32f4xx_hal_msp.c') diff --git a/src/short-test/src/stm32f4xx_hal_msp.c b/src/short-test/src/stm32f4xx_hal_msp.c new file mode 100644 index 0000000..6bf0b9d --- /dev/null +++ b/src/short-test/src/stm32f4xx_hal_msp.c @@ -0,0 +1,77 @@ +/** +****************************************************************************** +* File Name : stm32f4xx_hal_msp.c +* Date : 08/07/2015 17:46:00 +* Description : This file provides code for the MSP Initialization +* and de-Initialization codes. +****************************************************************************** +* +* 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.
