Node red reset counter for frequency measurement

Good day all,

I am using a RevPi core S 8gb with a DIO module connected.
I want to do some frequency reading from a digital input.
For that i try using the counter function from the DIO module and get this reading inside node red.
Is there a function available to do a counter reset from node red to determine the frequency, or is it possible to get a frequency reading direct from the DIO module?

Greetings William

Hi William,

as far as I know there is no support for counter reset in the third party RevPi Nodes. A possible workaround would be to use the EXEC node and call piTest -R with the respective IO name directly.
