PCM 3.185
PIC16F874
Dear All,
Does anyone know if there is a conflict if I do the following:
USE timer 0 via interrupts AND
USE standard CCS lcd drivers.
I have tried to use them together and I think there is conflict somewhere
Does anyopne know what resources the CCS LCD drivers take up??
i.e any interrupts/timers
YOUR FEEDBACK IS ALWAYS APPRECIATED

To answer this type of question, just look at the driver file, LCD.C.
This file will be in this folder: c:\Program Files\Picc\Drivers
If you see any functions with #int_xxx in front of them, then
that's an interrupt routine. Once you look at LCD.C, you will
see the answer. |

| Not all LCDs static |

Not all LCDs are static, that is the graphic LCDs have maximum clocking periods as well as minimum periods, so a timer interrupt could extend signals out of tollerance.
Try disabling the timer interupt before LCD functions, and re-enabling them afterwards. |
