Thanks for the reply, power was fine, 2 amps if needed, just sorted it out, I'm using the displays from Rapid Electronics, they have worked fine but when the Aout ng is connected it won't function, it is the RD 5 pin of the PIC, it won't drive both the display and Aout ng board, I've disconnected the display and have the Aout ng connected directly to RD5 and run the line to the displays through a 1K resistor and the display and analog out are both now working. Maybe the Rapid display's input's are pulling the line down too much, I'm no expert but the 1K works for me. Thanks again for taking time to reply, hope this helps someone else.
