@par Example Description
This example describes how to toggle the GPIO pins connected on AHB bus.
PD12, PD13, PD14 and PD15 (configured in output pushpull mode) toggles in a forever loop.
- Set PD12, PD13, PD14 and PD15 by setting corresponding bits in BSRRL register
- Reset PD12, PD13, PD14 and PD15 by setting corresponding bits in BSRRH register
In this example, HCLK is configured at 168 MHz.
@par Directory contents
- IO_Toggle/stm32f4xx_conf.h Library Configuration file
- IO_Toggle/stm32f4xx_it.c Interrupt handlers
- IO_Toggle/stm32f4xx_it.h Interrupt handlers header file
- IO_Toggle/main.c Main program
- IO_Toggle/system_stm32f4xx.c STM32F4xx system source file
@par Hardware and Software environment
- This example runs on STM32F4xx Devices Revision A.
- This example has been tested with STM32F4-Discovery (MB997) RevA and can be
easily tailored to any other development board
- STM32F4-Discovery
- LED4, LED3, LED5 and LED6 are connected respectively to PD.12, PD.13, PD.14 and PD.15.
