CA display means you are sinking current into the micro.
That should not be a problem, if the current per port pn deos not exceed the limits of the device. I assume you are using two 7 segment displays on two ports or you are controlling the Common lead from other port. Please explain some about your hardware. I have used one 7 segment display with 89C51 directly driven from port and had no problem at all. IA |
