Hello,

is it possible to create a defined pulse (length,initial value) at a Complex-GPIO-Output pin?

How can this be done ( timermode,period)?

I use beta2 sdk.

Best regards

g.

Hello,

i try to explain it more in detail.

I have one pin (pinA) configured as Interrupt-Input.

when i detect a falling edge, i want to create a pulse on another Pin (PinB).

pinA :  ---------------|_________|------------

pinB:  _________|--|______________

The length of the pulse should be configurable (< 1 msec).

It is not possible to do this with a timer and simple gpio(which i have tried),

so maybe it is possible with a cpmplex gpio.

 

Best regards

g.

Hi,

It does seem possible at first look. Can you please create a tech support case (MyAccount->MyCases) for this so that one of our engineers can look at the kind of flexibility you're looking at and the method that'll be needed to implement it.

Regards,

Anand
