Does anybody know if the rpi-gpio node can be used with a compute module (cm3) ?  
The pin out is different and the rpi-gpio node does not detect the board type.

Thank

HI.  
To do this, you need to find the file  
~ /.node-red/node\_modules/node-red-node-pi-gpio/nrgpio.py  
Open file in editor sudo nano nrgpio.py  
and change the line GPIO.setmode (GPIO. **BOARD** ) to GPIO.setmode (GPIO. **BCM** ), exit and save.  
Next, enter the GPIO number manually in the window below. For example GPIO16 = 16 but not 36.

Hi Ivan!

I changed the python script you've mentioned.

Just one question about "Next, enter the GPIO number manually in the window below. For example GPIO16 = 16 but not 36."

I don't see any window, where should I input the gpio manually?  
I am using the node node-red-node-pi-gpio.

Hi all,

Does someone have an answer to the question of Jamos1988? I'm stuck with the same problem: I don't see any window.

It now allows me to toggle a pin via the flow screen, however, nothing happens on the CM3.

Thanks in advance!
