OrangePi GPIO - 0% CPU

[Gab]

I want to build an multi thread program.

1 st thread modify the GPIO, and make accurate time for GPIO pulses. (I use WiringPI OP)

2 st thread create anything else.

 

Please write an thread example. I need thread sleep function (for 1 st thread). Expectation in the sleep the OPI CPU load=0%
