gps and gsm based tracking system using pic language

[dave cannacon]

friends i am doing a project on vehicle tracking system using gsm and gps ... i am doing in pic language .... finding difficult in writing entire program as i dont know much about pic language ...so can anyone post me the program

 

[sherazi]

just use C , if you mean pic assembly lang , then C is identical for all micro controllers, So please start with your project , build or get the hardware.. then start programming, show us what you have done and what you are trying to do and cant get done and I promise I would help!

Thats correct i will try and come back to you thanks

i have designed the circuit as attached. but unable to write program for it. if someone can help me i can tell him the program alogritham.

 

[sherazi]

start doing it this way [ i would give you the steps/algo]

this would just be getting started program that when made reset will make a call

define direction and status of ports etc
initialize serial port for 9600bps 

send a logic 1 to the pin connected to power key
delay 1 sec
send logic zero to pin connected to power key.

serial_send("AT\r");
delay 100 ms

serial_send("ATE0\r");
delay 100 ms

delay 7 sec
serial_send("ATDxxxxxxxxxx;\r"); // where xxxxxxxxx is a number u want the module to call
delay 100 ms

for(;;)

i need a code not alogritham/steps, i have my own steps which is different than yours. and the big problem is that how i can save cell number in EPROM like +92xxxxxxxxxx (13 digits including + sign or 14 replacing + with 00).

we cant code the complete project for you ... you should be asking for help in the manner you asked in this post... like how to save a number to EEPROM

how i can save cell number in EPROM like +92xxxxxxxxxx (13 digits including + sign or 14 replacing + with 00).

well Evey one has his approach. when I faced such a situation in my last design, I ignored the country code as my application was for a specific country. and saved just the last eight digits.

if you want to save the country code as well save it with + , reason being the modem would send you the number in this format always, both for sms and call.

Suggestion: use EMEM and Block write function of eeprom.h

I will just share some snippets of my code

#include <avr/eeprom.h>
.
.
.
uint8_t EEMEM M11[9];  // M11 is going to be the array stored in EEprom

eeprom_write_block ((const void *)&numb1, (void *)&M11, 9);//  would write 9bytes from numb1[] in ram to M11 on EEProm

eeprom_read_block((void*)&numb1, (const void*)&M11,  9);  // reads 9 bytes from M11 on EEProm to numb1 on ram

Hope this helps

what is the address location of EPROM can you write a example program just to save number in eprom ? i have not used EPROM before this is my first time. i will be thankful to you if you send me some line of code to save mobile number

 

[sherazi]

to understand this please follow this tutorial

example code

#include<avr\eeprom.h>

uint8_t EEMEM num_on_eeprom[9];   // this will allocate 10 bytes including the null byte at the end on EEPROM
uint8_t EEMEM num2_on_eeprom[9];   

uint8_t num[9];


//now suppose you want to save a number 99381960 to the first number num_on_eeprom 
strncpy(num,"99381960",9);  //copy the number to num
eeprom_write_block ((const void *)&num, (void *)&num_on_eeprom, 9);

similarly a second number can be added to the other location that we had defined on EEPPROM num2_on_eeprom

strncpy(num,"99381960",9);  //copy the number to num
eeprom_write_block ((const void *)&num, (void *)&num_on_eeprom, 9);


strncpy(num,"12345678",9);  //copy the number to num
eeprom_write_block ((const void *)&num, (void *)&num2_on_eeprom, 9);


// Reading is similarly done 
uint8_t number1[9],number2[9];

eeprom_read_block((void*)&number1, (const void*)&num_on_eeprom,  9);  // will copy the number from num_on_eeprom to number 1

eeprom_read_block((void*)&number2, (const void*)&num2_on_eeprom,  9);

I hope this would have helped
