Functions

• Start the program timer.
• Stop the program timer.
• Trigger the program timer.
• Check the program timer for reaching the set value.
• Check the program timer for operation.
• Program timer handler.

Using

To use the program timer driver in your project, follow these steps:

1. Include the necessary header files in your project:

 #include "universal_program_timer.h"

Example

!!!IMPORTANT!!!

It is necessary to place the universal_program_timer_handle() function in the interrupt handler, which is triggered every ms. The program timer is designed to handle small events (raising a flag, increasing a counter, etc.). It should not be used as a handler for large functions, as the callback is executed inside SysTick_handler, which can cause the entire system to freeze (due to the high interrupt priority)!
