GPIOTE/COUNTER

[ns murthy]

Can we use GPIOTE mechanism to capture timer /counter value automatically?

I want to use one GPIO pin.

Hi,

I'm not sure I understand what you mean. Do you mean that you want to trigger a GPIOTE event once the timer reaches a certain value?

Best regards

1. Start the timer/counter.

2. A change in level on one of the GPIO pins  should trigger the operation to  read the counter value. 

3. My question is whether we can realize the above using GPIOTE and a timer/counter  transparently.

Hi,

Yes,  this can be done by generating an GPIOTE event on any change and then using PPI to generate the task TASKS_CAPTURE[].  A good starting point for your project would be the GPIOTE example in the SDK.

Best regards
