Problem with pic16f877a
PostPosted: Mon Apr 05, 2010 9:19 pm     Reply with quote

My project by creating a tool MPLAB and PICC. I want to display text on screen glcd 128 * 64, I have some errors as follows:
Quote:

The target "C: \ projectA \ glcd not keypad-16F877A \ GLCD.o" is already up to date.
Executing: "C: \ Program files \ Picc \ CCSC.exe" + FM "main.c" EXPORT + + DF + LN + T + A + M + Z + Y = 9 + EA

D: \ projectA \ glcd not keypad-16F877A \ main.o ===> 3 Errors, 0 Warnings.

I use the PICC glcd.c library and I was adding more declarations
#include <16F877A.h> in PICC library and main.c , but still error.
Can someone tell me where I was wrong? Thanks you very much!
This is my program:
Code:

# Include <16F877A.h>
# Include "GLCD.C"

# Fuses HS, NOWDT, NOPROTECT, NOLVP
# Use delay (clock = 12000000)

void main ()
(
char text1 [3] [25] = ("orange that low com", "my middle tom," "My xao thit bo");
char text2 [3] [25] = ("cafe den da", "cafe da nau", "Water lemon");
glcd_init (ON);
glcd_fillScreen (1);
delay_cycles (10);
glcd_text57 (0, 0, text1 [0], 1, OFF);
glcd_text57 (0, 8, text1 [1], 1, OFF);
glcd_text57 (0, 15, text1 [2], first, OFF);
glcd_text57 (0, 22, text2 [0], 1, OFF);
glcd_text57 (0, 29, text2 [1], 1, OFF);
glcd_text57 (0, 36, text2 [2], 1, OFF);
)

Fuses, and clock setttings, _must_ be before code that uses them.
Layout should be:

Compiler include file
Device statements (ADC etc.)
Fuses
Clock settings
Setups for RS232/I2C etc..
Other include files
Main code

This can be tweaked a little (fuses after clock settings for example), but generally this is the order that things should appear for them to work.

Best Wishes
