hey, I'm working with GSM Sim 900 and I want to interface this module with PC. I'm taking ECG signals though electrodes and converting it to CMOS/TTL through MAX 232 and then I'm transmitting it to ATMega 128 which has 2 UARTs. One will be used in reading array of data and other will write and transmit the data to SIM900. Now, since I have very preliminary idea of Matlab/JAVA, I don't know how to implement s/w side. I eagerly need a source code which would help to interface Sim 900 to PC and then another so that I can extract my Analog ECG signals and show it on PC
