Using pigpiod remotely

The Using pigpiod does not need to run on the same machine as the client code. If you must run the client application in a computer other than your Raspberry Pi you can:

• Make sure the pigpiod daemon is running on the Raspberry Pi.

• Ensure that Dictel’s io1212 is connected to the GPIO port of the Raspberry Pi.

• In your client code, when initializing the pigpio library using pigpio_start, specify a non-NULL address, with the IP address or hostname of the Raspberry Pi.

• Optionally, specify the port where the daemon is listening.

For example, we can adapt the first pigpiod example (Example 1: Blink) to connect to a remote location by changing lines 31-32 as follows:

char *optHost   = "192.168.1.250";	// IP address RaspberryPi connected to io1212
char *optPort   = NULL;
