Hey there,
I had been working on Led-Dotmatrix display project using PIC18F46K22. I used CCS-5.008 compiler. Problem i am facing is that i need to save alot of patterns in rom (using 'const' keyword) to display on Dotmatrix. If i save more than one pattern, nothing displays on dotmatix. Although the circuit has been tested with another PIC (18F452) and it works fine using same code. I suspect that patterns are being corrupted in ROM. Everything (circuit and code) has been tested using 18F452 but it doesn't work for 18F46K22.
I have checked all the fuses and configurations. They are all fine as a simple Led Blink program works on 18F46K22 but its not working with DotMatrix.
Can anyone throw some light whether its compiler issue or any other. Any help would be appreciated.
Thanks.
