Modifying Nios II Device Drivers?

Hello BigGuiness.

Try this:

1. go to your components folder

2. make a new folder called altera_avalon_lcd_20x4 and copy the contents of the altera_avalon_lcd_16207 to the new folder.

3 edit the file called class.ptf in your new directory and change all instances of altera_avalon_lcd_16207 with altera_avalon_lcd_20x4.

4. save the file and start NIOS II IDE.

You should now have a new component called altera_avalon_lcd_20x4.

(if it doesn't work make sure the name of the new directory is EXACTLY the same as the new name in the class.ptf).

Now all you need to do is modify the driver ...

Let me know if it works :-)
