the Linux-Kernel manages the GPIO-system under the path /sys/class/gpio. Use the following commands to manage the pins (e.g. GPIO 17): activate GPIO 17: echo 17 > /sys/class/gpio/export deactivate GPIO 17: echo 17 > /sys/class/gpio/unexport configure GPIO 17 as … Continued
the minimal working configuration for an sipgate.de SIP-Account is: SIP Server = sipgate.de SIP User ID = <enter-your-user-id-here> SIP Authenticate ID = <enter-your-user-id-here> SIP Password = <enter-your-password-here> Now the phone can register itself through the SIP-protocol at your provider, e.g. … Continued
