Beginner in need of help !!

Hi,
MCLR is disabled by clearing the correct "fuse" in the CONFIG word. With PBP3 you set the CONFIG word(s) with the #CONFIG/#ENDCONFIG compiler directives (more on that in the manual). Your PBP3 installation folder has a subfolder named DEVICE_REFERENCES in which you'll find a file for each and every device the compiler supports. The file contains information about the various CONFIG options and also what defaults PBP uses if you don't include any in your code.

For a 12F683 the defaults are:

#CONFIG
   __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF
#ENDCONFIG

If you want to disable MCLR and keep everything else then copy/paste this into your program:

#CONFIG
   __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF & _CP_OFF
#ENDCONFIG

Hi Henrik, I am going to start my first project which will hopefully teach me new things along the way. I have question for you before I start though, I am hoping you can give a short answer to this.

Basically I want different modes (say 10) which are each cycled through via a tap of a tactile button (so mode 1, tap button, mode 2, tap, mode 3, etc) & each mode has its own led flashing at a different speed.

My question is, which way is the best to do this? With interrupts or something else? I would also like the chip to watch for other button presses as well not just this one sequence of modes, so its not going to be just a simple sequnce of button tap to next mode etc.

So I need a way of watching for multiple input changes all the time, I am expecting interrupts to be the answer after reading about, but just want to be sure

Hope you can help,
Rob
