Generate venn diagram from data. To implement a watchdog timer, we need to configure a timer that generates an interrupt at a fixed interval. As the result we get the new project with timer initialization function and interrupt handler.

Before You Begin, Ensure That You Can Build And Debug Embedded Projects For Your Stm32 Board By Following One Of Our Basic Stm32 Tutorials.

I've got a custom board with two stm32f4s (f411 and f446) that communicate via i2c.now, i have two dummy programs, where f446 is configured as i2c. We will also print a log message to console every time timer 2 expires. Tim6, tim7, tim14, etc ( consult the manual of the stm32 that you want to use) and are the most simple timers available in the stm32.
