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:~# gpio.sh
GPIO control aplication
Usage: /sbin/gpio.sh <ACTION> <NAME>
ACTION - set, clear, get, export, invert, dirout, dirin
NAME - SIM DOUT1 DOUT2 DIN1 DIN2 MON MRST SDCS RS485_R
Where:
- DOUT1 - Digital OC output
- DOUT2 - Digital relay output
- DIN1 - Digital input
- DIN2 - Digital galvanically isolated input
For example, to get the status of the digital OC output use the following command:
root@Teltonika:~# gpio.sh get DOUT1 0
The return value 0 means that the output is in Inactive (High level), i.e., OFF.
You can turn it ON (Active (Low level)) by setting its value to 1:
root@Teltonika:~# gpio.sh invert 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 into its opposite state.
To get the value of the analog input use the analog_calc command. For example:
root@Teltonika:~# analog_calc 7.2V
