Title: Curspr position
Post by: gtec on March 25, 2005, 10:08:14 am

I am using a MiniMax board. Does anyone know how to get the CursorSet in lcd.c to work beyond 15. If you write CursorSet( 18 ) for example it sets it to the 3rd character, not the 18th.

I guess this is happening because of the 4-bit addressing mode so it reads it as 2 instead of 18. Anyone know how to fix this????
