Hi,

 

i have some problems with my simple-gpio driver.

 

I want to set gpio19 to 0 and use therefore "echo O0 > /dev/gpio19"....

The problem is that the gpio19 only goes a few us to 0 and then again to 1.

 

How i can set the gpio19 always to 0 without writing a small programm...?

 

Thanks,

Patrick

you need to keep the gpio open, otherwise it gets released as soon as it is closed
