I have a speaker demo unit that currently has 12 channels. It uses a simple 12-position rotor switch to switch between speaker sets on the wall and sends 3v to an LED to indicate which channel is on.
I'd like to know if there is an LCD that can be connected via serial or usb and programmed to display a message when each channel is active. Untimately i'd like to display the speaker name and price. I guess what i'd need is the ability to flash an lcd with either serial or usb and send a pin on the LCD high with the lead that is currently going to the LED.
Thanks!
PS- In the future what Id really like to to is use one of CrystalFontz keypads like the 635 with a built in keypad and be able to trigger 12 separate relays using the Programmable I/O on the keypad using a menu system. That way my staff could program the channel labels on the LCD with the onboad keypad and customers could navigate the speaker wall using the Up/Down arrows...
Any insight as to how I'd acomplish this? I know the onboard memory isn't that big but all I need to display is the speaker model name and price.... or at least the "CHANNEL 1" thru "CHANNEL 12" lables...
