Hello all! I’ve been a lurker on here for some time but have finally committed to my DIY set up. One feature I wanted paired with my pre amp was an input selector which had a digital LCD layout. I’ve seen Teensy and Arduino mentioned on this forum but I’m not looking for any other data to be displayed outside of which I put in selecting along with a controller to switch between them. Has anyone successfully done this? For an idea of what I’m talking about if you look at a Nagra Classic Pre-Amp there’s a controller with a LCD display for the input selection. I plan on having a separate knob for my volume. Thank you in advance for the help!
Displaying only the selected input / channel maybe done easily with a 7-segment display writing 0-9 for upto 10 channels, using only some simple diode logic, instead of a microcontroller. However, if you want an LCD, I would suggest a 16 x 2 character display for which most compilers already have built-in libraries. Graphic LCD appears to be overkill.
