GPIO Pins
« on: December 29, 2016, 08:03:05 PM »
I've ordered a PiCap, but would like to still use the other GPIO ports for other lights (connected to solid state relays). So, two questions:


1. Are GPIO 17 and 18 the only ones that PiCap need to operate?
2. Is anyone aware of a sort of GPIO passthrough + ribbon cable that will allow both the GPIO to passthrough, and PiCap to connect, so both can work at the same time?


If there are only 2 PWM pins being used by PiCap, I'd like to make use of the at least 14 more!!

GPIO 18 and 19 are used by the PiCap for the WS281x pixel outputs.  You are free to use most other GPIO pins supported by FPP for other things such as GPIO input/output.

You can get shim modules such as this:   http://www.mcmelectronics.com/product/PIFACE-2445464-/83-16469  but some people have reported varying degrees of success with them.

Thanks Chris. I was more looking for something more like that 3-way ribbon cable that used to plug multiple CD Drives into a PC
