Display stopping Aoutng working

3 posts in this topic

Hi, tried to connect my Aout ng from my Midibox CV to my 1 year old fully working SEQ3 and found the Aout ng will only work when the core display is unplugged. Looking on the circuit they share the RD5 from the PIC. If I connect it to the display it stops the Aout ng from functioning but disconnected from the display and the Aout ng works? Is there anyone out there with any ideas as to how I get around this problem?

Power issue pulling down the rail?

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.
