PIC Scoreboard

[cne]

Hi,

I am working on a design for a scoreboard using flowcode. I have already made a rough draft of the code for the controller. The controller needs to send data over a couple wires to the remote display unit with large led displays.

My question is, how can I send data over a couple wires, and have it decoded at the other end to interface with led displays. Should I use a serial LED driver chip, or another PIC.

There is scoring, a timer, and period displays.

Each data field, example: Home Score, Guest Score, has it's own variable. The timer's 10's min, 1's min, 10's seconds, and 1's seconds have their own variable.

Thanks,

Cameron

Hello, Cameron.

As for your circuit, plan on having a microcontroller at the scoreboard end. This can easily do communications with a host computer and run the displays, including keeping time. A PIC MCU would be simple enough. For wire runs longer than a few feet, use RS485 in the connections. This means you use an LTC1481 IC at both ends of the wire. This will allow comms over hundreds of feet.

Have fun with your project.

So I lack the proper software to view it,
