You can control and monitor input and output values via a command line interface (CLI) with the gpio.sh command. You can execute this command without any additional options to get usage syntax examples:
root@Teltonika-RUT950:~# gpio.sh
GPIO control aplication
Usage: /sbin/gpio.sh <ACTION> <NAME>
ACTION - set, clear, get, export, invert, dirout, dirin, getpin
NAME - SIM DOUT1 DOUT2 DIN1 DIN2 MON MRST DOUT3 DIN3 RS485_R SDCS HWRST
Where:
- DIN1 - Digital input
- DOUT1 - Digital output
For example, to get the status of the digital output use the following command:
root@Teltonika:~# gpio.sh get DOUT1 0
The return value 0 means that the output is in Inactive (Low level), i.e., OFF. You can turn it ON (Active (High level)) by setting its value to 1:
root@Teltonika:~# gpio.sh set DOUT1 root@Teltonika:~# gpio.sh get DOUT1 1
As seen in the example above, you can change the value of an output by using the invert command, which simply turns the current value of the specified output and turns it into its opposite state.
