@par Example Description
|
|
|
|
How to configure the IWDG peripheral to ensure periodical counter update and
|
|
generate an MCU IWDG reset when a user button is pressed. The peripheral
|
|
is initialized with LL unitary service functions to optimize
|
|
for performance and size.
|
|
|
|
Example Configuration:
|
|
Configure the IWDG (prescaler, counter) and enable it.
|
|
Infinite refresh of the IWDG down-counter done in the main loop.
|
|
LED2 is blinking fast & continuously.
|
|
|
|
Example Execution:
|
|
When User Button is pressed, the down-counter automatic refresh mechanism is
|
|
disable and thus, reset will occur. After a reset, when re-entering in the main,
|
|
RCC IWDG Reset Flag will be checked and if we are back from a IWDG reset the LED2
|
|
will be switch ON.
|
|
|
|
Waiting a new user button pressed to re-activate the IWDG
