Read Output pin state

@dc42 @alankilian @gloomyandy @OwenD @SIam @Stephen6309
Thanks again.

Now that I have M118 working within Openpnp with GCode compression via the Backslash option I have changed my other analog sensor queries;

Initially using M308 was pretty verbose with 138 total char count

>> M308S0
<< Sensor 0 (Pressure_1) type Linear analog using pin temp0, reading 1996.0, last error: success, unfiltered, range 0.0 to 4095.0

Vs now using M118 a total char count of 50

>> M118P1S{sensors.analog[0].lastReading}
//actual Opnepnp syntax w compression and back slash
// M118 P1 S{sensors\u002Eanalog[0]\u002ElastReading}
<< 1996.0

Thanks Wayne

@wayneosdias
Glad it's all working.
Be interesting to see a video of it in operation

@owend
Will do, I need to get the mechanicals back together first.
If you dont know what this is, it's the aftermath drag pin machine crash. The pin with the bent tip slides up and down within the blue coil of the selenoid with the bent frame.

I hope to get fixed tonight and put some of my new and improved RRF commands to work

Thanks again.

Heres a quick vid of the process.

@wayneosdias Hi, is it okay to add a link to your wiki page on our wiki page here? https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_OpenPnP

@droftarts
Yes absolutely. I do need to make some tweeks to the wiki as I have been making changes but haven't been updating the wiki. I'll spend some time tonight to tiding things up a bit.

I don't want to spread any bad info so if you see anything that is not best practice please let me know.

Lastly, just to put the original topic to bed, M118 is the best method for retrieving input/output/analog values from Duet using GCode correct? Best meaning timely and succinct.

@wayneosdias Great, thanks.

For sending messages to USB, I guess M118 is going to be the most useful; I actually can't think of any other way to do it. If you wanted to send to DWC or PanelDue (but I don't think you do), use M291 instead.

Ok good to know, for Openpnp its USB/serial or tcp.

Ive updated the wiki, it is current. Feel free to post the link

You can also use 'echo' commands to retrieve information.
