Problem: Share GPIO pins between devices
#1
I've got an Inno-Maker RPI HiFi AMP HAT TAS5713 found here (amazon link, inno-maker's site appears to be down), and an Adafruit 16x2 Character LCD. I had this working last year but blew away the config unfortunately, and can't figure out what I did to allow the two to work simultaneously. 
When I have the Adafruit plugged in to the PI via the AMPs headers, the AMP isn't found in Moode, and I can't get anything to display on the LCD. 
I'm pretty sure I need to either map the GPIO used by the LCD to another pin, but not certain of that. Here's the LCD pin requirements.
In addition, I'm fairly certain the pins on the AMP correspond to the HifiBerry AMP+, as that's the amp I have selected in Moode.

From what I can tell, the LCD uses GPIO 2 & 3, while the AMP uses 2 & 3, 18-21, if I'm reading this correctly.

I'd greatly appreciate any help.

 I moved onto a different display. Thanks though.
