Hello,
I am new to this forum and this would be my first post. At my school we're in the midst of our exam project and the group I am a part of ran into a problem this tuesday.
First, a little introduction to the project. We're making a laser-tag like game which consists of a weapon, a vest and a command central. The weapon is simply an IR diode that emits a "shot". The vest receives this signal and holds how many lives that player has. It then transmits this in a sequence we made with radio signals. All that is working perfectly. The command central then gathers these signals and is supposed to output them to a status-display consisting of 10 7-segment CC displays. This is where the problem is.
When multiplexing the 10 7-segments from a PIC16F819 through a 4511 decoder all the displays are very dim. I've been reading through the forums for a solution but it seems it might be a problem to run 10 from 1 PIC as they are turned off for a long time before getting relit. A piece of the diagram is here:
**broken link removed**
The displays continue up with the same structure with the transistors being what controls which display is turned on.
We've tried different setups but they've all resulted in small bugs, I would guess because they're running too slow. The PIC is operating at 4MHz.
If you need any other information to help me out here, I'd be more than happy to fill you in, after all I am new to asking help for such things through the internet
