i'm intending to incoperate a gsm modem into my atmega 64 system, i have two analogues that i measure and then store in a SD card and then transmit the real time data by GSM.

has anyone out there done anything similar and give me some tips on the the interfacing of the SD card and the gsm modem.

Hi "VM TETWA",

Could you please inform, which SD card you have use & which library for
it.

And maybe some guide on how to use it.

Tks

Hi "VM TETWA",

GSM modem which u r using will have AT commands and SD card will have a pro=
tocol to work out with it, use them in your program in the way u want.

Hi

I have done a similar project...

I have interfaced MMC (multimedia card) with ATmega644P and GSM modem as well.
My speech recording and transmission system records speech data real
time on MMC and then after recording is done the speech data is
transmitter over GPRS link through GSM modem

Also i have interfaced GPS engine for transmitting locationh coordinates...

what data do you want to record ....

some telemetry data? like pressure,temperature etc.

Tell me a bit more about your system,i can halp you in this record

regards

yes it's a telemetry system whereby i'll receive analogue values of presure=
and temperature, store them and transmit them using GPRS and then plot the=
m in real time. I've been trying to search for some code examples for simil=
ar applications but haven't had any luck.

Well, as far as micro SD and MMC read/write codes are concerned, i
have seen it on many communities even, i have myself uploaded this
code to a couple of communities like edaboard, sonsivri etc.

I have got simulation of basic MMC read and write operations in
Proteus VSM and ICC AVR ...

If you have got Prtues VSM then i can email this simulation to you...

I haven't run this code on micrco SD card but as far as i have read
about Micro SD card, code written for MMC should also work for Micro
SD...
At what frequency would you like to take analogue samples for
recording on memory card?

I mean what would be the bulk of your data...?

GPRS has good application in sending telemetry data in bulk to a
particular IP address...

Are you using a modem with built-in TCP/IP stack or you have written
your own TCP/IP stack for GPRS connectivity

hi
i never tried using sd card but already on gsm.
my suggestion, you used nokia 6210 (old one). cause this gsm base on text mode. So it's more esier on sending sms.
you don't have to convert data on pdu mode.
i've tried on AT89S51 and atmega 8535.
sorry my english not good
regards
