Hi,
I am trying to use the C5505 ezdsp stick as a road-side audio sensor. I am currently working on the audio sampling, fitering and storing the audio data in EEPROM parts. But finally I will need to send the data to a central server over GPRS.
I am also working on the physical interfacing of the ezdsp stick with SIM300 GPRS modem from SIMCOM through a PCB using MAX3232 driver and DB9 male connector.
I used the SIM300 GPRS modem with the c5505 evm board (not the stick, the big one with lcd and all). There were nice UART examples provided, little modification of which allowed me to talk to the SIM300 modem using AT commands.
Can similar UART applications be available for the USB stick as well? The audio filter example has been of great help. I have modified it a lot to detect car horns from recorded audio and interfaced the program with the spirom application to store the data. If similar toy applications on how to access the UART be provided, it will be nice.
Thanks in advance,
Riju
