I'm trying to generate an interrupt on compare match of LowPower Timer. No luck until now, I tried everything using the HAL libraries, the AutoReload interrupt is correctly generated but not the compare match. Anyone succedeed in this?

Regards,

Fabio

Hi Fabio_IT,

You have the example STM32Cube_FW_L4_V1.1.0\Projects\STM32L476G_EVAL\Examples\LPTIM\LPTIM_PulseCounter.

In this example, there is an auto-reload each time the counter reaches the maximum value.

You can update this example to use compare match interrupt instead of autoreload match interrupt. The behavior with each interrupt is managed in HAL_LPTIM_IRQHandler. You will need to implement your own CallBack functions.

Hope this example bring you some help.
