Accessing Module Data
Lets read out some sensor values
Depending on the module you inserted, there is further information available by typing:
$ pilot module
For example the installed module in this case is a digital input module.
To access the pinstates from the filesystem you first export the pin with
$ echo 55 > /sys/class/gpio/export
now you can access the pinstate with the filedescriptor found at /sys/class/gpio/gpio55/value For this example we will use cat to read it
$ cat /sys/class/gpio/gpio55/value
When the pin is floating or connected to GND you will read 0. If you connect the pin to +5V you will read 1.
The documentation for all available modules can be found in the modules overview section.
