GPIO - Custom Serial Command

calex

Hello,
I've control card fan connected on GPIO 14/15, and I can use serial command to pilot the control card like
timer:Xh/xm; start; pwm:512; pwm:10%; stop; fast;
I've read the documentation but I'm not sure to know which option to select, it seems no one corresponds for custom command.
I would like to control the fan with custom @gcode for example when printing start/stop... Thanks

The GPIO solution is für digital i/o of pins and PWM if supported. It does not include using the serial pins. If you need them you need to write a external script that sends the command and call it with @execute cmd param. External scripts can be added in /var/lib/Repetier-Server/database/extcommands.xml - more details are in handbook and many examples on the forum here.

Top ! All is working fine. Thanks for your help.

So if someone is interesting, it's configured like that :

extcommands.xml :

        <command>

                <name>Ventilation 50%</name>

                <execute>/var/lib/Repetier-Server/alveo/start50%.sh</execute>

                <confirm>Démarrer ventilation à 50% ?</confirm>

                <local>true</local>

                <remote>true</remote>

                <print-permission>true</print-permission>

        </command>

script /var/lib/Repetier-Server/alveo/start50%.sh :

#!/bin/bash

 echo -ne "start;" > /dev/ttyAMA0

sleep 3

 echo -ne "pwm:50%;" > /dev/ttyAMA0
