[SOLVED] PIC18F25K22 + MikroC and JHD12864E(graphic LCD) problem

[ltsharma]

Hello,

I bought a new JHD12864E graphic LCD and PIC18f25k22 microcontroller + 4MHZ crystal,

i used Mikroc's GLCD example with changing of Rx to LATx
and ANSEL to ANSELA/B/C for this PIC,

compiled perfectly, in Proteus running perfect (with AMPIRE 128X64)

When on hardware connection

problem is when GLCD's VCC pin is kept connected there is nothing on display. if i removed VCC pin of GLCD for some seconds and connect back, it shows received data on display for few seconds and one side vanishes, again its not receives any new signals (data), have to disconnect and connect VCC back.

Circuit and code ?

Change this

---

Code C - [expand]
1
char GLCD_DataPort at PORTC;

---

to

---

Code C - [expand]
1
char GLCD_DataPort at LATC;

---

and see. If doesn't work then add

---

Code C - [expand]
1
TRISB = 0x00; TRISC = 0x00;

---

I don't have Proteus 8. so, post proteus 7.x format file. GLCD maybe defective. Try with another GLCD.

 

[ltsharma]

i did what u said,

output is

Proteus o/p


hardware o/p



Proteus 7 dont having pic18f18k22

 

[jayanth.devarayanadurga]

Zip and post the 7.x format Proteus file and also datasheet of your GLCD.

 

[ltsharma]

in my Proteus 7 no 25k22

GLCD datasheet
https://www.google.co.in/url?sa=t&r...=RhrsubnH-B4CPkpnc49BRQ&bvm=bv.51495398,d.bmk

[jayanth.devarayanadurga]

Add

---

Code C - [expand]
1
TRISE = 0xFF;

---

 

[ltsharma]

no change,

same result

HEYYYY...

i put image its came perfect

 

[jayanth.devarayanadurga]

Zip and post latest code. Mention Fosc used. Put a 100 nF Ceramic between power pins of GLCD.

 

[ltsharma]

FOSC means Config bits?

used 4mhz crystal with no pll

and another one, if i did

char GLCD_DataPort at PORTC;

Proteus output is good, but not works on hardware

- - - Updated - - -

WOHHHHHHHHHHHH its worked in hardware also,,,,

ONLY the small silly problem since,

needed to put

TRISB = 0x00; TRISC = 0x00;

THANX a lot jayanth, im struggling from last one month,

SORRY for disturbing you peoples
