reading lcd
Hi all,
i am working on 20x4 LCD with PIC18F452 and Hi-Tech PICC-18 Compiler
I am using LCD module given in samples directory.
My Project Continuously updates a counter on LCD and whenever RCIF goes high (Serial Reception Interrupt) I have to show a Pause Sign on the Upper Right Corner.
Whenever an Interrupt occur it does display it but after ISR my counter data which is to be displayed in the center start displaying in third line i figured the problem is the cursor location whenever i returned from ISR LCD cursor did not returned to the previous location where it was.
I need a routine /method how to read the cursor's current location and so i can get rid of this problem please advice.
