Gentlemen:

I'm making a device that show the time and temperature with a 16F84 and it
work fine with led display of 1" in size, so when I try to use led displays
of 4" size, the segments don't
turn on...
In the led display spec's, I saw the connection diagram and it's made with 5
leds connected in serial mode for each segment (common cathode), except for
the decimal point that have only one.
All the device is powered with standard +5 Volt regulator, the segments are
driving directly from PortB thru limiting resistors and each display is turn
on every 3 mSec. via transistor from portA.

Can anyone please help me with this problem?? I will appreciate it!!!

Thanks & excuse for my english....
