Hello,
I want to order the light of my machine directly from the mocca screen. How to link a button (button8 for example) with the light output. In
The party program that should go with Lazarus. The name is "moc.button.8"?

My file hal
.....
# Eclairage (pin 25 OUT)
setp hm2_5i22.0.gpio.025.is_output TRUE
net eclairage-on <= iocontrol.0.moc.button.8 ?????
net eclairage-on => hm2_5i22.0.gpio.025.out
......

For now nothing works :( , but I do not despair :unsure:
thank you to him who gives me an idea.

If you comment out the new lines, then start mocca, then, in a terminal window type:
halcmd show pin
That should give you a list of all the pins, hopefully giving the full correct name of the mocca button pin.

(put the output on pastebin.org perhaps)

Your pin listing shows that there is no pin called iocontrol.0.moc.buttton.8, your code needs to be:
# Eclairage  (pin 25 OUT) 
setp hm2_5i22.0.gpio.025.is_output TRUE
net eclairage-on  moc.button.8  => hm2_5i22.0.gpio.025.out

I am not sure if the mocca buttons latch, if you find that the light is on only when the button is being pressed, then I can show you how to add some more HAL components to make it work properly.

I have never used Mocca, but my guess would be that the buttons don't exist until the GUI is loaded.

Move the button 8 "net" statement line to the custom_postgui.hal file.

Hello,
Thank you Andy, why I did not think!
That was the problem.
