Hey,

is there a way to use the GPIOs with interrupts instead of polling the sysfs? I'd like to analyse PWM signals of up to 200 Hz on an input without taking too much system ressources and thought, interrupts would be a better way to go. Or is there any other ressource saving manner to analyse a PWM signal (frequency, duty cycle) on an input pin?

Is there the newer GPIO character device API instead of the sysfs available on the RUT955?

Hello,

For this request of yours it would require additional analysis and development from our RnD and for that you may contact your sales representative for this such kind of request.

Thank you and have a nice day!

Regards.

So, no chance with the existing firmware?
