Hi everybody,
How is it possible to use 4 digits to the PIC16F628A without multiplexing?
I have noticed that by multiplexing appears a flickering, I have four CD4094 and I want to use.

Hello,
Yes it is possible to drive four 7-seg displays without any flicker.
After you have drawn the first character add a delay of around 2ms, then repeat this for the other characters and this should help to stabilize the display.
Not sure if the Proteus sim will be flicker free but I think it should be.
