Parameters
HwGpioNum – I/O port number:
1
–
8
NumOfStep – the maximum number of steps: for analog =
0
–
255
, for digital=
2
(see notes)
CurrentStep – the actual step depending on the measured voltage

Notes
The Set command can only be used for analog.
In digital in mode the response is 2 and the current state: 0 , 1
In analog mode the response is 0 to [
NumOfStep
minus 1].
In digital out mode an error is returned.
Example
Set I/O port number 1 number of steps to 5:
#GPIO-STEP 1,5<CR>

Parameters
HwGpioNum – I/O port number: 1 – 8
LowLevel – voltage: 500 to 28000 millivolts
HighLevel – voltage: 2000 to 30000 millivolts or 2000 to 4000 when pullup is enabled.

Notes
This command is only relevant for digital input. There must be a minimum of 800 millivolts between the low
and the high levels.
Example
Set I/O port number 1 voltage low level to 500 millivolts and high level to 2000 millivolts:
#GPIO-THR 1,500,2000<CR>
