Disable peripherals in debug mode on STM32F4xx

Have you ever used watchdog in your application? Have you ever debug your application when watchdog was enabled and you hit stop? Watchdog did not stop in this case and when you pressed “continue” in your debugger, your program starts over because WDG has reset your system. One choice is that you remove line where you initialize IWDG, but you then must recompile and redownload and all that stuff. Wasting useful time. To avoid this problem, STM32 devices have possibility...

Library 20- Independent watchdog timer on STM32F4

Sometimes you need watchdog timer to look at your system if it gets stuck. I made a little library to work with it. Watchdog in STM32F4xx device has it’s own clock which is independent from main system clock. You have to constantly reset it’s counter value or it will elapse and reset MCU. Watchdog Library Features Detect if system was reset by watchdog Supports different timeouts Reset watchdog

All STM32F4 libraries

Because there is a lot of libraries I have done, I will make a table with all of my libraries at one place. When new library will be created, it will be posted here. These libraries work on both Discovery boards, if not, it will be specified. Actually, libraries should work on STM32F4xx series of microcontrollers if they have peripherals that are need for library. All STM32F4xx MCUs don’t have everything inside. 🙂 Libraries are tested on my 4 STM32F4...
