interfacing NOKIA 1100 GLCD

nokia glcd

Hello,

I am trying to interface graphical display of 1100(controller PCF8814) with AT Mega 16.I have pasted the program below.The LCD does not work.Please tell me if something is wrong.

#define CHECKBIT(x,b) x&b
#define SETBIT(x,b) x|=b;
#define CLEARBIT(x,b) x&=~b;
#define TOGGLEBIT(x,b) x^=b;

#define SCE 0x08
#define DC 0x04

The hardware connections are as below

XRES----------->PA2
SCE------------->PA3
SDIN------------->PB5
SCK-------------->PB7
VDD and VDD1 are given 3.1V supply
VSS is ground.

Please help me to find out the problem.

With Thanks and Regards

Hi Vikky,
can you please tell me where did you get this program? I had been searching for code for this LCD but I found nothing on the net...

I also have found this code and it does not work. I guess the timing is not right and/or the initalization parameters are wring.

I have read the PCF8814 datasheet and there is an initialization parameter about LCD voltage. This project was using 5V. Mine is 3v3.

Att

u have used nokia 1100 right?
how do u interface the phone with the atmega32 or atmega16?
is there a circuit diagram available for this and what r the components required for this?

hi,

i actually used this code for 3310 and it worked.then i switched over to 1100.circuit and code was for 3310 and was available in a efy.i changed the circuit according to 1100.it didnt work.infact i tried continously for an week. it didnt work.i dont know why.

could u plz share the circuit diagram and the code for 3310 if u hav.. else atleast specify the isssue no. of the efy u referred.
thanks and regards

Click to expand...

send your mail id.i will mail you the details.

---------- Post added at 16:04 ---------- Previous post was at 16:02 ----------

code i have already shared above.the above code is for 1100...do you want code for 3310 also?

my id is: keshav.pearl@gmail.com

the code for 1100 would be more helpful but u said that it is not working. if that is the case then 3310 code will also do. but if there is anyway the 1100 code could work then it would be great. i also need the details for hardware interfacing.

thanks for ur help.

regards
