MCXA153 ADC TRIGGER

_Ferrari_ — Fri, 01 Aug 2025 14:24:21 GMT

Dear all,

I'm developing a project based on the MCXA153VLH microprocessor.

It needs to sample an incoming analog voltage at regular intervals. I thought of using a timer to trigger the ADC to start the conversion.

I know that the ADC module of the MCXA153VLH microprocessor supports up to 4 hardware triggers, but I can't figure out the correspondence between the hardware peripheral and its specific trigger.

By analyzing the demo software provided with the SDK, I understand that Trigger 1 is associated with an IRQ generated by a pin. Which trigger is associated with a timer?

Thank you for your help and cooperation
regards
