You might simply try searching the forum....
Have answered this in the last few days.
Basically, with CCS, follow the following layout in your code:
First include the processor file - in your case #include "16F877A.h"
Then add any other device lines (ADC=10 etc.)
Then setup your fuses
Then setup your clock
Then your RS232
These may all be in a single 'project' include file, but should still be in this order.
Then have any defines needed by later include files (so pin defines for LCD, etc.).
Only now, include the other files (flex LCD etc.).
Then have your other code.
Order is _vital_. You cannot define any memory arrays etc., _before_ the processor is defined. Similarly, you cannot use RS232, or delays, before the clock is defined, etc. etc..
Best Wishes |
