ASCII input by 3x4 kbd then displayed to LCD forming 8 chars

[OMER]

am looking For a C code to input ACSII with 3x4 keypad then sent to 16F877 then sent to 2 x 16 LCD.
the ACSII from A-Z (same as mobile txt writing method) where the cursor moves to the next position on the LCD after a bottn been idle,
kbd_getc() and LCD_putc() functions are used. Omer

Did you look at the CCS example files ?
If you have version 3.xxx of the compiler, look for
these files:

c:\Program Files\Picc\Examples\EX_LCDKB.C
c:\Program Files\Picc\Drivers\LCD.C
c:\Program Files\Picc\Drivers\KBD.C

If you have vs. 2.xxx of the compiler, all these
files will be in this folder:

c:\Picc\Examples

the Kbd sends a char of 0-9 & A and B (3x4 only) to the LCD.
but what am looking for is a code that change the apperance of the char on the LCD acording to the number of clicks, and the cursor moves to the next char position on the LCD if no botton been clicked within a certain period. (like typing a txt message using a mobile phone ).

example buttons corresponds to letters
botton 2 gives 2, A, B, and C.
botton 3 gives 3, D, E, and F.
botton 9 gives 9, W, x, y, and Z.
and Etc

the code reads the incoming char from the kbd then output it to the LCD acording to the number of clicks.
please if you think of any way of doing it please e-mail me,
Omer

Hi. I'm working in a project just like this (3x4 keypad working as a "mobile" keypad, 2x16 LCD and PIC 16F877A).

Did you managed to find any solution? If yes, could you please post the C code?

Thank you for your help.

Set a timer (or more likly n x overflows); count the number of button clicks until timer over, updating the charcher on each click; with a case statment on the number of button clicks. When timer finished then fix character and move onto next. Thats how I would do it.
