nokia 3310 lcd sce

hello..
i am working on a project that involves use of a nokia 3315 lcd. i have written the program in mikroC. i am using PIC18F452 as controller.

but when i assembled the circuit and applied +5 volts to it, noting appeared on the screen.

please look at the code and comment.


I have used the schematic similar to the pic with difference of processor.

Added after 2 minutes:

the code is:





Code: 
					// Connections between PIC and LCD.

#define D_C  PORTD.F5
#define SCE  PORTD.F4
#define RES  PORTD.F3
#define SCK  PORTD.F7
#define SDI  PORTD.F6

#define pi 3.14159					// Constant pi.
#define num_of_points 64			// Number of points to plot in a graph.

void initlcd(void);					// Initializes the LCD.
void sendcmd(char);				// Writes a command.
void senddata(char);				// Writes data to DDRAM to illuminate the pixels.
void cleanram(void);				// Erase the DDRAM contents.
void gotoxy(char,char);			// Position cursor to x,y.
void sendchar(char);					// Write one character.
void sendstr(const char *);			// Writes a string of characters.
void sendpack(char);      


const char table[480] = {	0x00,0x00,0x00,0x00,0x00,	// 20 space		ASCII table for NOKIA LCD: 96 rows * 5 bytes= 480 bytes

Added after 5 minutes:

one more thng i have used three LEDs in order to debug the program at PB7,PB6 and PB5. they glow at different instant in the program.

these leds were wworking fine as per program. so my guess is that Program is working iside the chip..Also through PRoteus i have checked the SPI communication.it is also as expected.

i heve checked each annd every connection many times.
so i think either the LCD is faulty or i have done something wrong in initialisation routine....



please help..
thx in advance

Added after 24 minutes:



Added after 28 minutes:

wait a min...
when i used inverse mode (sending 0D istead of 0C in init routine) i am getting routine, i can see a very light output in the screen.


now the only question is how to increase the contrast of the display????

any idea???

nokia 3310 lcd interfacing with pic using mikroc

Hi i am also trying to interface a nokia lcd to a PIC16F84A.
I am writing code in MikroC. The voltage level of the PIC is 5V from a 7805 chip. The voltage levels for LCD are brought down using a resister voltage divider.



But my LCD is not showing anything at all.
Can someone check out if my coding is right.........or is ther someother problem with my setup?

As of now i am just trying to print some arbitrary thing in the first column of the first bank.( X address 00 and Y address 00 and some arbitrary data)

Regarding the code....The PIC sends command data using function Command(); The arguement is the data in decimal form(not in HEX)

Any help will be appreciated..

lcd will work even on 5V supply. no need to use resistor.

routine lcd 3310 mikroc

Thanks

That is fine but working the LCD at 3V shudnt affect its functioning.........can someone check if my code is right?
 
nokia 3310 contrast

your cellphone has a 3.7 v battery.
if you read the data sheet you will know it can work from 2.5 v to 5 volts.

hi ! would like to ask if have the codes in assembly language instead of C? Thank You
 

Re: proteus nokia 3310


It's a 5x8 matrix of codes to send to the display. If you look at them in binary they make more sense, for example this is the code for "#"


00010100b // 23 #
01111111b
00010100b
01111111b
00010100b

See the pattern?

Why are people saying the LCD is OK at 5V? The data sheet says 3.3V.
 

lcd can work from 3 volts up to 7 volts.

>lcd can work from 3 volts up to 7 volts.

FFS! Yes it can work up to 7V, but then a 12V light bulb will work at 15V; just not for very long.

If you want the device to behave reliably, stick to 3.3V as in the specification.
 

what does that mean when u asign RES as PORTD.F5? any explanation for us begginers to understand the flow of the code.

It would be helpful if you could quote the exact area to which your question refers.

Do you mean this bit of code? I've added comments.

Code: 
#define D_C PORTD.F5 // LCD Data/Control 
#define SCE PORTD.F4 // LCD Serial Enable
#define RES PORTD.F3 // LCD Reset
#define SCK PORTD.F7 // LCD Clock
#define SDI PORTD.F6
// LCD Data

Here RES is defined as PORTD.F3 (not F5) but all this code is doing is giving meaningful names to the port connections to the Nokia LCD: D_C, SCE, RES, SCK and SDI are all shown in the data sheet.
