[PIC]:
Thank you for suggestions those come from
Aaron Lahman, Spehro Pefhany, Jinx, and Dale Botkin.

I have it tried with a transistor as a driver for every column, when tested
every columns sink about 40 mA
to the GND. BUT whenever connected to the PIC16F84
every columns sinks only 3 mA. I wonder if the scanning
frequency coused the brightness down. However, when the led connected to
frequency generator with 128x50 Hz
the light strill bright, mean while the scanning frequency have adjusted to
128x50 Hz.

Again, thank you  in advance.
I'm waiting for any suggestion.
