please help me.
 

cheap gps modules for projects in mumbai

ya its possible to connect both to 8051, I suppose you will just be receiving data frm the GPS module and not sending anything to it
and as for GSM module you will be sending as well as receiving data
so connect the GSM module to the 8051's com port and use basic serial program for it as for the GPS module connect it to P3.2 and use sofware based communication also called as bit banging
check this link to learn how its done:

Its easy to do it, use a relay for connecting GPS and GSM to controller through serial port. At power on Let it read GPS data store it in eeprom.after 10 sec change over the relay and read the data and send it through sms to required number. or keep on polling the GPS data, whenever the data changes send sms. If you need the circuit and any help , please feel free to contact me.

Thanks to all.


I dont know how to use relay in this communication if you have circuit
please send it toa this email (fatima_project@yahoo.com) and talk more about
programming.
 

aarlogic c07/4

use 2serial ports instead. Yes any typical 8051 has only one but you can always Bit Bang for othrt using any free IO lines for Rx Tx. Try googling for serial bit bang
 

gsm gps atmega

Thanks for this code but it is difficult to understand it without circuit or berief description for it.
please help me more.
 

gps mcs51

this is very good but my project it is simple more than this one

ok I dont use programm on computer but I want to use the same owner phone to send request to gsm in my system then it will read data from GPS and send it to owner but I am think the gsm need phone number not the same owner number .

(is this possible idea).

(I am not use RTC and external memory)

Can you please provide us schematic diagram for these design?

i wonder what is the purpose of connecting the device to the computer base from the block diagram that were posted?

does it mean it is connected to the computer box of the vehicle?

can anyone answer my question??

also how can the output from the GPS can be shown to the computer in the office?? as shown from the block diagram and from the description, the GPS only gives the longitudinal and latitudinal coordinates of the vehicle. does it need a map to output its exact location on the computer?

anyone pls
 

8051, gps

Hi
Actually I do not know why the MC connected with the computer .
When you receive the coordinates you should use a map like googlemaps. you can do it manually by putting the longitude and latitude , or you can do it automatically if you can deal with http files. Because googlemaps provide an open source program called API and there is an example to locate a marker on googlemaps, check this link :
https://code.google.com/apis/maps/documentation/examples/
I hope this helped you

What about to use the Arduino Shield listed here Arduino with GSM GPRS GPS Shield plus one of the Arduino clones like Amicus18.

The Amicus18 is an embedded system platform based on PIC architecture 18F25K20. It can be programmed with any programming language, though the Amicus IDE is completely free and extremely powerful.

Hi Meff_
Thank you for your answer ,could you please can you give me more details or schematic of connecting the GSM moden to RS485 for both master PIC and Slave PIC

thank you ,best regards
ibralfy
 

EIA-485 - Wikipedia, the free encyclopedia

Please take care that you will have with RS485 TX and RX only and no hardware hand shake lines. For SMS or small to medium data on GPRS is it ok.
Without RXD and TXD you will may loose data during transmitting.

Anyhow, a GSM modem has its RX and TX and this is with further lines normally wired to RS232. Maxim is offering pin compatible chips that supports RS232 or RS485.
