#174617 - That could be step 2

Does the LCD controller have a text mode? If so, try that, it is lot simpler.

You really need to establish that you have working read & write routines before you do that.

So the plan could be:

1. Create working Read routine(s) - test by reading some suitable registers;

2. Once you have the Read routine(s) working, get Write routine(s) working - test by writing to some registers, and reading back;

3. Once you have the Read & Write routine(s) working, try something simple in Text mode - this demonstrates that you can fully communicate with & operate the display

4. Now you're ready for graphics mode. Again, proceed step-by-step, starting with simple lines and building up...
