| Why my OCMJ4X8C-15 LCD doesn't work, and LCD no display |
 Posted: Mon Aug 16, 2010 10:38 pm |

Hello guys, I use the PIC16F877A +12864LCD +CCS. When I download my program, it doesn't work. I don't know what is wrong in my program.
My connections:
| Code: |
the LCD pin ----16F877A pin
vss--GND
vdd--5v
vlcd--nc
RS--------------RC2
RW--------------RC7
Enable----------RC6
DB0-------------RD0
. .
. .
. .
DB7-------------RD7
PSB-------------RC1
RST-------------RC5
VOUT------------NC
LED- -----------GND
LED+ -----------5V

Pls who can give me a demo about 12864LCD. I can't find the error in my program.
Give me some advice! |

One problem you have is this:-
| Code: |
const unsigned char TAB1B[ ]={' ', ' ', 'W', 'W', 'W', '.', 'P', 'I', 'C', '1','6', '.', 'C', 'O', 'M', ' '};
//In main
print(5,1,TAB1B[2]);
// print routine
void print(uchar x,uchar y,char* str)
{
uchar lcd_temp;
set_xy(x,y);
lcd_temp=*str;
while(lcd_temp != 0x00)
{
lcd_data(lcd_temp);
lcd_temp=*(++str);
}
}
|
you pass print a pointer to index 2 of TAB1B, your TAB1 tables are NOT null terminated. The print routine requires the string to be null terminated. Your routine will continue outputting data passed the end of the TAB1B array until it reaches a null.
The last char in your tables needs to be '\0' or just use
const char TAB1B[] = " WWW.PIC16.COM";
No idea why the 2 spaces are there at the beginning or the space at the end. |

you don't actually give us any idea of what is happening.
Do you get any output ?
Is your code actually running ? How do you know ? |

Does your code actually compile without errors.
I don't think you can declare pointers to constants the way you did. |

This is not correct. Look in the CCS manual and read about a function
before you use it. The manual says:
| Quote: |
bit_set( )
Syntax: bit_set(var, bit)
Parameters: var may be a 8, 16 or 32 bit variable (any lvalue)
bit is a number 0- 31 representing a bit number. 0 is the least significant bit.
|
Look in 16F877a.h file to see the #define statement for PIN_C2:
Notice that it's not a bit number (0 to 31).
My advice is, don't write your own lcd driver. Read the data sheet for
your LCD and see what LCD controller it uses. Then find a CCS driver
that is already written for it. (Your links don't go to a LCD data sheet
so I can't help you find it).
CCS graphics lcd drivers:
| Quote: |
c:\program files\picc\drivers\hdm64gs12.c
c:\program files\picc\drivers\sed1335.c
|
T6963 driver:

| guys ,my code compile no error , my LCD no display ,you can copy my program to your CCS compiler in order to debug it,you only get 4 warning but no error. |

i could copy your code and compile it but I can not run it. I dont have
PIC16F877A Development board
or
12864LCD
So I can only help you based on what you post here. If you don't post what I ask then I can not help you.
What are the warnings ?
How do you know it is running ? |

It would have been better without the 16f877a.h header file (unless you have changed it) and if you used CODE tags.
I still can not see the compiler warnings either.
I think there may be a problem with your fuse settings as well. Mabey you need NOLVP but I am not sure of this. |

I will make your display to work, don't be so worried.
Please use 16F877A which I used when I first displayed image on 128x64.
Make sure that the pin connections are like this....
* 1: VSS is connected to GND
* 2: VDD is connected to +5V
* 3: V0 - LCD operating voltage (Constrast adjustment)
* 4: D/I - Data or Instruction is connected to B2
* 5: R/W - Read or Write is connected to B4
* 6: Enable is connected to B5
*7-14: Data Bus 0 to 7 is connected to port d
*15: Chip Select 1 is connected to B0
*16: Chip Select 2 is connected to B1
*17: Reset is connected to C0
*18: Negative voltage is also connected to the 20k Ohm POT
*19: Positive voltage for LED backlight is connected to +5V
*20: Negavtive voltage for LED backlight is connected to GND
and then just copy and paste the programme into your compiler ....
