| T6963C moving Data line from PORTB to PORTD problem! |
 Posted: Sun Dec 28, 2014 10:26 am |

Hello,
I am still can't solve this problem. Please help me. When i am using PORTD (changed everything in T6963c library for using PORTD). When system turn on on GLCD shows irregular black spots. What is the problem.
Sorry for my english.
I am thinking:
1-) Expecting a #FUSES command
2-) Expecting make passive a PORTD feature
3-) Expecting using pull-up or pull-down resistor for PORTD
CODE:
| Code: | #include <18F452.h>
#include <T6963C.c>
#include <Grafikler.h>
#include <Animasyonlar.h>
#include <stdlib.h>
#FUSES HS
#use delay(clock=20000000)
int deger;
char deger_str[];
void main()
{
setup_psp(TRUE); // PSP birimi devre dışı
setup_timer_1(T1_DISABLED); // T1 zamanlayıcısı devre dışı
setup_timer_2(T2_DISABLED,0,1); // T2 zamanlayıcısı devre dışı
setup_adc_ports(NO_ANALOGS); // ANALOG giriş yok
setup_adc(ADC_OFF); // ADC birimi devre dışı
setup_CCP1(FALSE); // CCP1 birimi devre dışı
setup_CCP2(FALSE); // CCP2 birimi devre dışı
ekran_temizle();
Resim_goster(LoadMomentIndicator,240,128,0,0); // "LoadMomentIndicator" ekrana basılıyor
delay_ms(100);
ekran_temizle();
Resim_goster(MesaElectronics,240,128,0,0); // "MesaElectronics" ekrana basılıyor
delay_ms(100);
for(int a=0;a<=126;a=a+14)
{
glcd_box(51+a,91,62+a,108,1); // İçi dolu dikdörtgen
delay_ms(10);
}
ekran_temizle();
Resim_goster(AnaGosterge,240,128,0,0); // "AnaGosterge" ekrana basılıyor
while(true)
{
deger = 4;
itoa(deger,10,deger_str);//float to string işlemi gerçekleştiriliyor
glcd_box(66,68,110,87,0);
glcd_text57(68,72,deger_str,2,1);//voltaj_str değeri ekrana yazdırılıyor
delay_ms(500);
}

No. It is "no storage allocated for output string from itoa" in the code below:
| Quote: | char deger_str[];
itoa(deger,10,deger_str); |

could be a simple solution...
you need a 'delay_ms(500)' in main before doing an lcd_init(); to allow most LCD modules time to 'stabilize' before the PIC tries to access them.
or
it could be a power supply problem, not enough current capacity at 5 volts to properly power the GLCD module.

hmm....
from your code...
first line in main()
...
setup_psp(TRUE); // PSP birimi devre dışı
...
The Parallel Slave Port is on PORTD so you do NOT want to enable it(true).
has to be (false) to disable the peripheral.

i also tried with "setup_psp(FALSE);" but didnt work again. I ordered another model GLCD. And i am waiting it. I will reply again last status

ok... back to basics...
does a simple 1Hz LED program work ?
This will confirm PIC is good, xtal is correct, programmer downloads properly.

hmm.. another question
Did you have it working on PORT B at all THEN change to PORT D?
If possible, I'd start with the 'default' of using PORT B.

My code working very well with PortB. When i change the T6963C library about data port changing commands. System didn't work.
Note: My codes working very well with portD on PROTEUS ISIS***
I can't understand the "what is problem?"

ARRRGH.... ISIS !!!
When posting you MUST tell us if you're using REAL HARDWARE or defective simulator called ISIS/Proteus....
No wonder it 'doesn't work', it isn't REAL hardware.
ISIS.Proteus is KNOWN to NOT work. It is FULL of bugs, errors, faulty DRCs.
WHEN you get REAL hardware, then I can help.
I am not going to fix ISIS, life is way too short.

temtronic i am not a liar. i said my codes working in ISIS and don't working in REAL HARDWARE. and AGAIN i am NOT A LIAR. your experiences is not enough for this problem. I understand it. Thank you !

Ok, you have to understand that just because 'it works' in ISIS does not mean it will work with real hardware. A project will 'work' in ISIS without caps on the xtal, MCLR properly hooked up,etc.
Based on hundreds of posts I've read ,when anyone says ISIS, I usually assume they're 'working' within ISIS, not real hardware.
Since you say that the hardware worked fine using PORT B. then there are 3 things that will not allow the GLCD to function on PORT D.
1) bad PIC. easy to confirm, simply do the 1Hz LED test on each I/O pin.
Also, go back to using PORTB,see if it still works. If not, could be a bad GLCD as it did work...
2)bad setup code,. as I pointed out any peripherals used by PORT D must be disabled. Typically that includes PSP, ADC ,CCP, UARTs,SPI, etc. I don't use the 452,best to check the datasheet.uC and CCS defaults are not digital I/O to the pins.
3) incorrect pin assignments for the GLCD. perhaps in modifying the driver(hopefully a copy, not the original), one PORTB assignment wasn't remapped to PORTD.This will cause 'garbage' to be displayed.
To avoid any confusion... can you please confirm that the 'PORTB version' of your program does work with real hardware?

Since you're getting black squares, here and there, it really could be either a bad PIC or a minor coding issue. |

Post a schematic of your connections on your hardware board to the
Newhaven GLCD.
How to post a schematic:
Use http://www.postimage.org or http://www.imageshack.com
or some other free image hosting service.
Upload your schematic to that website. Preferably a .JPG file or some
other commonly used image format.
Then post a link to your image here in the forum.
-------------
Edit:
Updated first link.
