One version (LCD.C) comes with the compiler. More flexible, and generally as/more reliable, is the 'flex lcd' driver in the code forum.

But don't anything happen. Where is my wrong ?

| Because things have to be defined _before_ they are used. How is LCD, meant to know about your pin definitions?.... |

Why did you define the lcd pins as TRIS register settings ?
The CCS example in the lcd.c file doesn't do this.
Why did you do it ?
Here is the CCS example from lcd.c, and it shows pin numbers:
| Code: |
//// Example of pin access:
//// #define LCD_ENABLE_PIN PIN_E0
//// #define LCD_RS_PIN PIN_E1
//// #define LCD_RW_PIN PIN_E2
//// #define LCD_DATA4 PIN_D4

I don't care what you want to do. If you use a driver written by someone
else, the driver will tell you how to use it. You must follow the
instructions in the driver to make it work correctly. If you invent your
own way, the driver will not work.
Fix the #define statements for the lcd pins the way that I showed in
my previous post.
Also fix the order of the #define statements and the #include for lcd.c
as shown in this post:
http://www.ccsinfo.com/forum/viewtopic.php?t=47663&start=1
If you do those two things, then you have a chance for the lcd to work. |
