The IWDG timeout is set to 280 ms (the timeout may varies due -to LSI frequency dispersion). - -SysTick is configured to generate an interrupt every 250 ms. In the SysTick interrupt -service routine (ISR), the IWDG counter is reloaded to prevent an IWDG reset, and -a specific GPIO pin is toggled. -An EXTI is connected to a specific GPIO pin and configured to generate an interrupt -on its falling edge. -In the NVIC, this EXTI line corresspondant interrupt vector is enabled with a -priority equal to 0, and the SysTick interrupt vector priority is set to 1 -(EXTI IT > SysTick IT). - -The EXTI Line is used to simulate a software failure: when the EXTI Line event is -triggered (by pressing the Key push-button on the board), the corresponding interrupt -is served. In the ISR, the GPIO pin turns off and the EXTI line pending bit is -not cleared. So the CPU executes the EXTI line ISR indefinitely and the SysTick -ISR is never entered (IWDG counter not reloaded). -As a result, when the IWDG counter reaches 00h, the IWDG generates a reset. -If the IWDG reset is generated, an other specific GPIO pin is turned on after -the system resumes operation. - -If the EXTI Line event does not occur, the IWDG counter is indefinitely reloaded in -the SysTick ISR, which prevents any IWDG reset. - -In this example the system is clocked by the high-speed external (HSE) clock (8 MHz). - - -Directory contents -================== -platform_config.h Evaluation board specific configuration file -stm32f10x_conf.h Library Configuration file -stm32f10x_it.c Interrupt handlers -stm32f10x_it.h Header for stm32f10x_it.c -main.c Main program - - -Hardware environment -==================== -This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation -boards and can be easily tailored to any other hardware. -To select the STMicroelectronics evaluation board used to run the example, uncomment -the corresponding line in platform_config.h file. - - + STM3210B-EVAL - - Use LD1 and LD2 leds connected respectively to PC.06 and PC.07 pins, and the - KEY push button connected to PB.09 pin. - - + STM3210E-EVAL - - Use LD1 and LD2 leds connected respectively to PF.06 and PF.07 pins, and the - KEY push button connected to PG.08 pin. - - -How to use it -============= -In order to make the program work, you must do the following: -- Create a project and setup all your toolchain's start-up files -- Compile the directory content files and required Library files: - + stm32f10x_lib.c - + stm32f10x_gpio.c - + stm32f10x_rcc.c - + stm32f10x_nvic.c - + stm32f10x_iwdg.c - + stm32f10x_flash.c - + stm32f10x_exti.c - + stm32f10x_systick.c - -- Link all compiled files and load your image into target memory -- Run the example in standalone mode (without debugger connection) - -******************* (C) COPYRIGHT 2008 STMicroelectronics *****END OF FILE****** -- cgit v1.2.3
