IWDG is a 12-bit down-counter clocked from an independent internal clock source. The IWDG is clocked by its own dedicated low-speed clock (LSI) and thus stays active even if the main clock fails. When the next timer period ends, our modified value of TIMx_ARR is automatically written into the auto-reload register by the hardware, so our modified value will take effect in the next timer period. General notes for setting the watchdog. Read about 'ARM: STM32 Independent Watchdog Example' on element14. // Define the Base address of the RTC registers (battery backed up CMOS Ram), so we can use them for config of touch screen or whatever. For example, in my project, the shortest wake-up period is 16 seconds, and the average dog has only a few seconds. My code uses a lot of timers for packet timeouts, for example. The STM32 HAL makes it a little easier to use, as there's some built-in functions that control the DMA with the ADC, specifically. A Simple STM32 Example Project.

Hi I'm trying to learn to use interrupts in my projects, specifically I want to be able to use sleep mode in order to make battery powered projects. STM32H7 watchdog does not correctly reset. The IWDG will use whichever is enabled. To do this, we simply run the program without resetting the watchdog timer. You need to follow the below steps to reset the device using the watchdog timer. Write an infinite loop to toggle the PB0 bits toggles with a certain delay. The major difference between the two is Independent Watchdog can be reset at any time before the timeout occurs, but the Window Watchdog. My board is a nucleo STM32L432KCU board. One option is to reconsider and using interrupts after all; and move the FSM into the …. It has few beneficial features, including a separate 128kHz clock source, reset the microcontroller, and generates an interrupt. Under Mode, change Interface to CMSIS_V2.
