hi
I am crazilly looking for help to build moving message display controlled by sms by 3310. can any one please help?????????/ how can i understand AT commands? can i use it for NOKIA 3310????????/
hi to all
this is the program for moving meesage display that i download it from this topic .
i want to show my own message I AM LIREZA MOHAMMADI ) in the output.
what change i shoud do in this program?
/*
MATRIX FORMAT
ROW & COL ACTIVE HI

typedef unsigned char byte; /* type define objects with */
typedef unsigned int word; /* more classical microprocessor */
code char menu[] =

" d to display message/r/n/n/n/n";
// this loop is the heart of the scroll
// message is scrolled until a key is hit on the keyboard
while (1) {
// load led array
tmpDataPtr = dataPtr;
tmpCharOffset = charOffset;
tmpCurrentChar = currentChar;
for (i = 0; i <= 31; i++) {
ledArray = *tmpDataPtr++;
if (++tmpCharOffset==0x06) {
tmpCharOffset = 0;
if (++tmpCurrentChar == messageLength)
tmpCurrentChar = 0;
tmpDataPtr = &matrix[msg[tmpCurrentChar] - 0x20][0];
}
}
if (++charOffset == 0x06) {
charOffset = 0;
if (++currentChar == messageLength)
currentChar = 0;
}
dataPtr = &matrix[msg[currentChar] - 0x20][charOffset];
// display led array
row = 1;
for (j = 0;j <= SCROLL_DELAY; j++) {
for (i = 0; i <= 31; i++) {
LED_DATA = (ledArray & row) ? 1 : 0; //invert image by interchng 0:1
LED_CLOCK = 1;
LED_CLOCK = 0;
}
P1 = row;
row <<= 1; // next line to be switched on
if (row==0x80) row = 0x01; // if last line go back to the first line
delay_us(1100);
P1 = 0x00;
}
}//while

You cannot use AT commands on Nokia 3310, it uses FBUS protocol
if you want AT commands use 6210 or 6310 instead, these models work on either
FBUS (DAU-9P cable) or AT Commands (DLR-3P cable).
can you guys tell me that what is more easy to use fbus or to use ATcommands??? my second question is tha I read that NOKIA 3310 uses Fbus and Mbus then how to select any one of them?
i am a fifth year comp engneering student and i need a schematic diagram and a program of a programable running message. iam using a 5x7 dot matrix. and i really need a help.cos i am using a keypad controller to change the content of the running message.
Hi
I want LED DotMatrix Display that is controlled by PIC16F877A. I want to control it by Keyboard. So, please if you have any idea about this, help me.
