stm32l031k6 and Comparator Setup and interrupt

[RadaR]

Thanks for your great project.

I am newbie in ChibiOS. I my project i need to use a Comparator 1 and Comparator2 (stm32l031k6, need to setup and configure Comparators and in interupt code - perform time critical code ).

Can somebody help or give link to comparator's sample in ChibiOS?

Really need community help.

Hi,

In ChibiOS there is no direct support for comparators, if you find generic code then it could be integrated with some effort, there we could help.

I forgot about that, you can give it a try. It is into the ./community directory in ChibiOS.

Note that code in ./community is contributed and not necessarily maintained, you may need to make adjustments.

Hi, i need a help of ChibiOS's Contrib community.

I am newbie in ChibiOS architectory. So faced with promblem when adopting COMPv1 to stm32L031 (M0).

In stm32l031 (Mo) Comparator uses interrupt - ADC1_COMP_IRQHandler same that a ADC.

But in COMPv1 - STM32_COMP_1_2_3_IRQ_PRIORITY (COMP_1) and and STM32_COMP_1_2_3_IRQ_PRIORITY (COMP_2).

As i understand ChibiOS HAL use ADC1_COMP_IRQHandler for ADC HAL Driver? Or i can change library to use ADC1_COMP_IRQHandler?

Hi,

The ADC handler should not be used on the L0, you should be able to use it for the comparator.
