Quad encoder problems

[SteveB]

Since you are using a serial LCD and software based serial routine, the interrupts will be disrupting the timing of the serial output. I would recommend using HSEROUT. The timing won't be affected with the interrupts.

EDIT:
Here is how you can do this:

1) Switch your serial cable to RB2 (pin 8)

3) Setup the HSER defines:

'Setup for 9600 baud 
' Set transmit register to TXEN =1 (TX enabled) and BRGH = 1
     DEFINE HSER_TXSTA	24h
' Set baud rate
     DEFINE HSER_BAUD	9600

3) Change your SEROUT2 commands to HSEROUT.

HSEROUT [254, 88] 'Clear LCD

and

HSEROUT [254, 71, 1, 1, "ROT1:", DEC2 RotEnc1_val," ROT2:", DEC2 RotEnc2_val]
