Follow Up… Adding a button to GPIO.17 toggles the LED's on GPIO18 & GPIO19. import RPi.GPIO as GPIO GPIO.setwarnings(False) GPIO.setmode(GPIO.BCM) GPIO.setup(17, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) GPIO.setup(18, GPIO.OUT) GPIO.output(18,0) GPIO.setup(19,GPIO.OUT) GPIO.output(19,0) try...

Follow up… Tested GPIO18, GPIO19 with a simple LED / Python script. Everything worked as expected. import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) GPIO.setup(18,GPIO.OUT) GPIO.setup(19,GPIO.OUT) print "LED on" GPIO.output(18,GPIO.HIGH)...

I actually saw it on your site. So far it's very good! I think it will answer most questions new users have.

> I should have been more explicit. I'm using a RaspberryPi 3B+. Are the pins the same? I realised that was a dumb question. Follow up hopefully not as dumb… Is there are mapping from GPIO 18/19 to port 1/2? I'll take a stab and say yes… GPIO 18 = Port 1 data, GPIO 19 = Port 2 data?

I'm going to check the pins on the board to see if any of the solder is busted or the connections don't look right. > They are GPIO18 and GPIO19 and on pins 12 and 35. I should have been more explicit. I'm using a RaspberryPi 3B+. Are the pins the same?

Thanks for the hint Al. I ran the tests with power going into each of the 12v and 5v but with different data sources. End result is: * 5v lit up when powered by the 5v and with port 1 data * 12v did not light up when powered by the 12v with port 2 data Seems like the port 2 data is not...

From the manual > Using the WS2811 outputs disables the onboard audio and external usb audio must be plugged in and configured if needed. Is this still the case with the rPi-28D+?

I had a fully working display which consisted of a mix of 5v strip and 12v pixels. The display was powered by a rasberry pi 3 and a rPI-28 controller. A week ago I decided to update FPP from v3.3 to the latest which included a full os reinstall. When I plugged everything back in the 5v lights...
