I bought a similar shield from seeedstudio and followed the instructions on their wiki. I got it to work by sending it AT-commands (which this shield apparently accepts too), but have not tried the SMS/GSM specific library, which I assume is just a wrapper for the AT commands. Check and see if your shield will respond properly? I am curious whether you will get this one working OK, because it's a little cheaper and I would buy it instead. BTW: If your Arduino is connected (or will be connected) via USB to the computer, then the USB is using 1 & 2, and the shield uses two digital pins via the Serial library. To that effect, starting with Arduino 1.0, you should try the SoftwareSerial. Bahar E Shariat Pdf Free Download. h library that is built-into the distribution.

Finally, I found (via some google searches and confirmed this) that when using the SoftwareSerial (or NewSoftwareSerial) library to communicate, you should reduce the shield's baud rate. I do this across each interface to keep consistent with the following on startup. I am using sim900 library the sms library, softwareserial,wire.h and a rtc( real time clock ) library. I just read in the library example that if the ram is getting full the program would keep on restarting. My code is also acting wierd,but my memory usage shows aboout 17kb from 30kb. Although i think there is some conflict between the Sim900 and wire.h library. Because the program would keep on restarting at wire.begin() when i use the wire.h library only.

Any solutions? I2C protocol may be causing a problem someone said to me, makes sense because sim900 also said it uses something like that, but dont know how. Libraries i used: #include 'SIM900. Oregon 1000 Kilometers Rar Extractor. h' #include 'sms.h' #include 'SoftwareSerial.h' #include 'Wire.h' #define DS3232_I2C_ADDRESS 0x68. There is a playground page that might be of interest: There are three kinds of memory on the Arduino - Flash, where the code is stored, SRAM, where variables and literals are stored, along with the stack and heap, and EEPROM, where persistent data can be stored. The message 'Binary sketch size: 17,542 bytes (of a 32,256 byte maximum)' refers to the Flash memory used. There is nothing that reports the amount of SRAM used, because it changes as the program runs. As local variables are created, the heap grows.
