* Use the new gpio(4) semantics and change the command line syntax to ambalmer2008-11-261-105/+151
| | | | | | | | | | | more readable and straightforward format. Note that there is no longer a default GPIO device, but it has to be sepcified on the command line always (and as Theo mentioned, newfs also does not default to /dev/sd0a...) You must do a 'make includesi' in /usr/src before building this command or before your next system build. ok uwe@

The gpioctl program allows to manipulate GPIO devices pins Quick start for the Soekris net4801 users: # gpioctl -c 20 out pp # gpioctl 20 1 This will turn on the red error led. If you want to use JP5 I/O pins, just use the /dev/gpio1 device. Quick start for the PC Engines WRAP.1C users: # gpioctl 40 This will read the state of the button (0 means pressed). # gpioctl -c 2 pp out This will turn the first led on, to turn off write 1 to the pin, it's reversed. For the second and the third leds use pins 3 and 18. ok deraadt@
