Using conditional gcode to evaluate a value

[jay_s_uk]

I've just added switches to detect when a tool is installed to my printer.
I can then identify which one is fitted and dock it accordingly if needed.
IO inputs are available in the OM but how do I evaluate them using conditional gcode?
i've tried

if sensors.gpIn[0] = 1

That should work, You can use:

echo sensors.gpIn[0]

to check the state from the DWC console.

I get this if I try echo in the console

echo sensors.gpIn[0]
Error: Failed to evaluate "sensors.gpIn[0]": unsupported type code 11

The error from code I tried in post 1 is

Failed to evaluate "sensors.gpIn[0] = 1": cannot convert operands to same type

Which firmware version are you using?

PS - using recent firmware (preferably 3.01-RC12) you would need to use:

if sensors.gpIn[0].value = 1

That worked. Thank you!
