Sometimes my 4-digit display stops showing the upper two digits. If I swap out the display for an identical one it works fine. If I put the original back in it's back to normal.
Is it possible I'm damaging the PIC by drawing too much current? I have a 16F886 connected to a 4-digit CA display. PortB to the segments. PortC.0-3 to the digits. No resistors.
I've run this TONS of times, though, and never had a problem until today...I'm making a tachometer and I have PortA.5 as analog, reading the output from an IR transistor.
Any ideas what's happening?
