Firmware for PIC based audio announcer card

The scope of the project is to develop firmware for a PIC microcontroller based pcb.

There are 11 opto couplers on the board. The optocouplers takes signals from the 7 segment LCD that I am running using an arduino and 7 segment display. The cables are looped from the 7 segment LCD and are connected to the pitch screws on the card.

When the opto couplers are triggered the micro controller plays the associated MP3/WAV file stored on the micro SD card through the amplifier to the speakers. There must be a volume controller for the audio.

Attached gerber files, schematic and required logic.
