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/Makefile | 49 ++++ src/short-test/README | 15 ++ src/short-test/include/stm32f4xx_hal_conf.h | 401 ++++++++++++++++++++++++++++ src/short-test/include/stm32f4xx_it.h | 57 ++++ src/short-test/include/stm_init.h | 18 ++ src/short-test/src/main.c | 270 +++++++++++++++++++ src/short-test/src/stm32f4xx_hal_msp.c | 77 ++++++ src/short-test/src/stm32f4xx_it.c | 54 ++++ src/short-test/src/stm_init.c | 202 ++++++++++++++ 9 files changed, 1143 insertions(+) create mode 100644 src/short-test/Makefile create mode 100644 src/short-test/README create mode 100644 src/short-test/include/stm32f4xx_hal_conf.h create mode 100644 src/short-test/include/stm32f4xx_it.h create mode 100644 src/short-test/include/stm_init.h create mode 100644 src/short-test/src/main.c create mode 100644 src/short-test/src/stm32f4xx_hal_msp.c create mode 100644 src/short-test/src/stm32f4xx_it.c create mode 100644 src/short-test/src/stm_init.c diff --git a/src/short-test/Makefile b/src/short-test/Makefile new file mode 100644 index 0000000..671f600 --- /dev/null +++ b/src/short-test/Makefile @@ -0,0 +1,49 @@ +# put your *.o targets here, make should handle the rest! +SRCS = main.c stm_init.c stm32f4xx_it.c stm32f4xx_hal_msp.c + +# all the files will be generated with this name +PROJ_NAME=short-test + +TOPLEVEL=../.. +include $(TOPLEVEL)/common.mk + +OBJS = $(SRCS:.c=.o) + +################################################### + +.PHONY: lib proj + +all: lib proj + +lib: + $(MAKE) -C $(STD_PERIPH_LIB) STDPERIPH_SETTINGS="$(STDPERIPH_SETTINGS) -I $(PWD)/include" + +proj: $(PROJ_NAME).elf + +$(PROJ_NAME).elf: $(SRCS) + $(CC) $(CFLAGS) $^ -o $@ -L$(STD_PERIPH_LIB) -lstmf4 -L$(LDSCRIPT_INC) -T$(MCU_LINKSCRIPT) -g + $(OBJCOPY) -O ihex $(PROJ_NAME).elf $(PROJ_NAME).hex + $(OBJCOPY) -O binary $(PROJ_NAME).elf $(PROJ_NAME).bin + $(OBJDUMP) -St $(PROJ_NAME).elf >$(PROJ_NAME).lst + $(SIZE) $(PROJ_NAME).elf + +clean: + find ./ -name '*~' | xargs rm -f + rm -f *.o + rm -f $(PROJ_NAME).elf + rm -f $(PROJ_NAME).hex + rm -f $(PROJ_NAME).bin + rm -f $(PROJ_NAME).map + rm -f $(PROJ_NAME).lst + +really-clean: clean + $(MAKE) -C $(STD_PERIPH_LIB) clean + +debug: + $(GDB) -ex "target remote localhost:3333" \ + -ex "set remote hardware-breakpoint-limit 6" \ + -ex "set remote hardware-watchpoint-limit 4" $(PROJ_NAME).elf + +flash-target: + $(OPENOCD) -f $(OPENOCD_BOARD_DIR)/$(OPENOCD_PROC_FILE) \ + -c "program $(PROJ_NAME).elf verify reset" 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). diff --git a/src/short-test/include/stm32f4xx_hal_conf.h b/src/short-test/include/stm32f4xx_hal_conf.h new file mode 100644 index 0000000..0b85bd9 --- /dev/null +++ b/src/short-test/include/stm32f4xx_hal_conf.h @@ -0,0 +1,401 @@ +/** + ****************************************************************************** + * @file stm32f4xx_hal_conf.h + * @brief HAL configuration file. + ****************************************************************************** + * @attention + * + *
