You must _never_ enable an interrupt, without the code to handle it being present.
Why on earth, do we seem to have dozens of posters, suddenly trying to use 'interrupts' for things that they are not designed for, without the first idea of reading the data sheet, and some basic books about processor hardware first...

Then _you_ need to do the learning.
Sorry, but my niece was handling code better than this at 5 years old. Her biggest problem was spelling the instructions, a custom dictionary to the spelling checker soon solved that.
_Everything_ you need to know, is available on the web, with some research, this is _not_ a schoolroom, it is a group to _help_ people having specific problems with the CCS compiler. Your questions are far more basic than this... |
