My GLCD not Work with 18F452. Work only with 16F877A

[Gerson]

Hi!. Excuseme for my bad English. (Speak Spain)

Executing the example of CCS, EX_GLCD.C @20Mhz in PIC18F452 don't work but work fine in PIC16F877. Test with new XTAL and new Capacitor 20pF and not change. Only garabage. The GLCD is GDM12864M, and work whit GLCD.C, KS0108_me_EP4.C drivers, but only with PIC16F877A.

The config fuses for PIC18F452 are:

#include <18F452.h>
#device adc=8

#FUSES NOWDT //No Watch Dog Timer
#FUSES WDT128 //Watch Dog Timer uses 1:128 Postscale
#FUSES HS //High speed Osc (> 4mhz)
#FUSES NOPROTECT //Code not protected from reading
#FUSES NOOSCSEN //Oscillator switching is disabled, main oscillator is source
#FUSES NOBROWNOUT //No brownout reset
#FUSES BORV20 //Brownout reset at 2.0V
#FUSES PUT //Power Up Timer
#FUSES STVREN //Stack full/underflow will cause reset
#FUSES NODEBUG //No Debug mode for ICD
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#FUSES NOWRT //Program memory not write protected
#FUSES NOWRTD //Data EEPROM not write protected
#FUSES NOWRTB //Boot block not write protected
#FUSES NOWRTC //configuration not registers write protected
#FUSES NOCPD //No EE protection
#FUSES NOCPB //No Boot Block code protection
#FUSES NOEBTR //Memory not protected from table reads
#FUSES NOEBTRB //Boot block not protected from table reads

#use delay(clock=20000000)


setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_psp(PSP_DISABLED);
setup_spi(FALSE);
setup_wdt(WDT_OFF);
setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);

Really ¡Thank you for help me!

[PCM programmer]

Does the 18F452 work if you try a simple program, such as the one
shown below ? This program will blink an LED on Pin B0.

[Gerson]

Hello PCM Programmer. Thank You for respond.

The compiler version is 4.013

Yes, Work fine with certain code with out LCD. Change the PIC for New and the problem persist. Only not work the part referent to GLCD.

Change for a other Power Supply, For a New crystal, asemble circuit in Printed Circuit Board, Program with PicStarPlus (Olimex), program with ICD1 (Olimex), program ICSP and Sockedted and the problem persist.

Use compiler into MPLAB v7.43 and the result is equal. Test with drivers glcd.c, hdm64gs12.c, ks0108_me_ep4.c. Tes with other code and examples, Test with reset conect to Vdd, direct and with 4k7, 10k, 47k resistor, Test with #define fast_glcd, etc, etc, etc.

Test the code in the proteus 6.9 and work fine.

#include "e:\MSDOC\W\000 - C-UG37[OK]\452\rx\ug37rx.h"
#include <hdm64gs12.c>

Very Tank You for Help Me.

[PCM programmer]

My first suggestion is (if possible) download vs. 3.249 of the compiler
and try that version.

You said it worked OK in Proteus, so that implies that it could be a
hardware problem. However, I still think the first thing you should
do is try it with vs. 3.249.

[Gerson]

Ready! Download v 3.249, Compile and unchanged. The problem is the same.

Question??? HardWare Problem ??? But only for PIC18F452 ???

For what razon 16F877A, Work Fine and 18F452 not. Really misterious this problem.

Other idea???

[PCM programmer]

You need to post a complete program, that shows the problem.
The program must be compilable. So far, you have only posted
pieces of a program. I copied the pieces into MPLAB and tried
to compile it, but some parts are missing, and doesn't compile.

You need to post a compilable program.

For example, what is in this file ?

[Mark]

The first thing I would do is correct the glcd.c driver. The driver ignores whether or not the device is busy. This can lead to problems. What you will notice is garbaged data on the display. From past experience, what I have seen is the MSB of the data byte being set. The reason for this is because the driver writes pixels. It must read the data currently there, modify it and then write it back. If the device is busy, when the data is read back, it will be invalid and thus create the garbage. You might also try slowing down the 18F452 as a test.

[Gerson]

Hello Mark !!

The first thing I would do is correct the glcd.c driver. ???

How ???

My experience in "C" or CCS is the only 2 month !

Make delay in the drivers of GLCD?. You have a driver correct for the GLCD ? Really very tank you for post your correct driver.

Hello PCM Programmer !!

All the codes with GLCD and 18F452 are problem in my CCS. (Or I'm?).

The following codework very fine with 877A. But not with 452. ¿The config for my GLCD is import ?

This pieze of driver show the config of pins.

Than You for Help me to Every One!!!

[Mark]

Here is an example of what I mean. You will need to implement it yourself.

[PCM programmer]

Your program is too complicated for a test program. I would delete
about 95% of your code, and make a small test program. Then it's
possible that the problem could be found.

[someone]

Hi

Please try to increase the value in the command 'delay_cycles(value)' in the driver file 'HDM64GS12.c' so e.g if the command is 'delay_cycles(5)' in the driver then change is to 'delay_cycles(10)'

Hope this helps

Best Regards

[Gerson]

Hi! Very tank you for tour help!!!

The solution for my problem is increase the time in the GLCD library.

Very tank You Mark and Someone
