Single PIC to Blink 5 LEDs Independently?

[Darrel Taylor]

Would I gain any better resolution/exactitude of timings by increasing the oscillator?

The timing is maintained by the CCP module and Timer1. Those periods will remain the same reqardless of the CPU's frequency.
Increasing the frequency will only allow more instructions to be executed between periods.

The way I left it, only 4.5 mS of the 10 mS periods are being used to run the 5 led's.
You should be able to add 2 more without any problems.
