Hi to all:
First of all, happy new millenium  to all.
I am making my own Pic-Trainning Board whereby I can do practicing
most/all peripherals it gets ( PIC17C756 & PIC16C76 ). I have tested the
7-seg display with 470 ohms to @ pin and I realized that they are have a
cathode comun. But now I would like not use those resistors as they are
many  for ( Two 7-seg displays ).  Am I going to ruin them as voltage
output,Voh and current output Ioh  are 5.5V and 25mA respectively? they
are FND 507 from Korea. Anyone who has already experienced this p'se
give me an advice for time saving.
Regards,
Ismael.
