TDC1000-TDC7200EVM: Is it possible to get UART data without turning on the desktop program?

Part Number: TDC1000-TDC7200EVM

I want to mount my TDC1000-TDC7200EVM to a mobile vehicle. Now it needs to be connected to the software and after I load all the register I start the graph which starts giving me values through UART in arduino, Is it possible to get UART data just connecting the board to a power source? If so, How? Thanks in advance for your help.

Regards!

    Hi Nabeel,

    Can you explain the setup a bit more? Are you transferring the data from the MSP430 on the EVM to an Arduino microcontroller, or have you disabled the MSP430 and are only using the Arduino to communicate with the devices?

    In either case, whichever microcontroller you are using can output the UART stream regardless of whether or not anything else is listening on the communication lines. The UART output is simply up to the firmware that is installed on the microcontroller.

    Thank you for repyling, I am transferring the data from the MSP430 to an Arduino. Now I am only getting values when I press "Start Graph" in the GUI. How can I get values without using the GUI at all? Should I turn on the "Continous Trigger" to get values in the Arduino without the need of the GUI later on.

    Hello Nabeel,

    You will either need to modify the firmware on the MSP430 to continuously set the the Start New Measurement bit in the TDC7200, or you will need to use the GUI if the MSP430 is the only device communicating with the TDC parts. If the arduino is communicating with the TDC parts, then you can just set the Start New Measurement bit in your arduino's code.

    Regards,
