Hi,
I'm trying to use the GPIO on the Raspberry Pi.
After I export a GPIO before setting its direction I need to wait until
all Folders and files of the GPIO pin are created.
I try this with:
FileDirectory default fileExists '/fullPathToTheGpio/direction'
This never returns true.
Any hint on how to find out when I can start writing to the file?
I I just wait 3 seconds before writing to the pin for the first time it
works. Subsequent writes work instantly.
Thanks,
Herbert
