Other Parts Discussed in Thread: TMS320C5515

I just bought this KIT.I want to connect this KIT with a mobile phone/GSM module and send the data through SMS.But i couldn't find any way of doing this.Can you please help me in this.I just want direct communication between the KIT and the Phone/GSM module.I will be thankful to you.

    Most GSM Modems communicate through RS232 using AT-Commands (standard-modem and GSM-specific set of commands). You need to refer to the datasheet/manual of your GSM modem for the specific COM port settings and the list of AT-Commands.  

     

    Once you have that information you can refer to the TMS320C5515 UART User’s Guide (linked below) to correctly setup your RS232 port.

    Please note that the UART of your FDK is currently being used by the MSP430 MCU (at the bottom of the extension board) to control the buttons and speaker. When using the UART (RS232) for the GSM modem, you will need to find other ways to add these features if you need them; just as an example, you may send Enroll, Match or Del_All commands remotely via SMS using your GSM module. 

     

    Good luck and regards, Nelson

    Is it possible to use GPIO's for UART??

    Yes, it is possible to implement a software-UART using GPIOs for low baud rates. But generally is not worth the effort and the extra use of CPU resources. In this particular case, for the FDK, I would recommend using I2C or SPI to communicate with the MSP430 and use the hardware-UART for the GSM modem. Also, there are GSM modems with SPI and/or I2C interfaces in the market, but they are less popular and might not be a cost-effective solution.
