Dear Piclist,

re. Range check when limits are in RAM
I have an app. where speed of execution is paramount while looking for the range but the range limits can be calculated at leisure in which case...
...the sums 255-hi and hi-lo+1 can be evaluated and stored in 2 RAM locns.
The ADDLW are replaced with ADDWF and I have a 2 instr. range test. It still fails if hi is 255 and lo is 0 which is a shame. It would be a simple way of including an always true condition.

regards,
Colin Smith

Hi, for my B.E. project i have to generate a variable PWM signal. i am using PIC16f877. i am using TMR2. clock of 20MHz.
PR2=0xff. i have to increase the duty cycle till there is a match between a certain values in a 2 gen. purpose regs.
Hope to get some help and if possible the asm program from you.
thank you

I am also trying to use Tony Kubek's code, but to write to a Compact Flash card using a PIC16F877. I also require the macros.asm file. Is there any chance of getting hold of it? Cheers!

Hi. I have to research using a PIC processor to control the movement of a motorised web cam, just simple movement - up/down and left/right. Would anyone know which would be the chip to use? and how I might have to wire it all up?? Any help on this problem would be greatly appreciated. Many thanks.....Ko
