MSP430F5528: sending the tof measurement data from tdc1000-tdc7200evm to arduino

Part Number: MSP430F5528
Other Parts Discussed in Thread: TDC1000, TDC7200, MSP-FET

Hi,

I am doing a project to measure the distance using radio waves. I am using TDC1000-TDC7200EVM to measure the Tof. Now my doubt is, can I connect the EVM and arduino directly and read the data from EVM. or 

I need to write any code for uart communication to EVM. 

If I need to write the code then how can I do it.

    Hi,

    You would need to use a serial connection with the arduino (it could also be with SPI or I2C). You would need to check if there is an available eUSCI (serial) module with pins that are exposed on the EVM, and then write the serial communication code. You can find code examples for this on the MSP430F5528 product page.

    Hi,

    The IDEs that are suggested and supported for MSP430 are Code Composer Studio and IAR. Code Composer Studio (CCS) is available here: www.ti.com/.../CCSTUDIO

    Hi,

    As you suggested I have installed the ccs software and understood the working.But in debug session it is not connecting to the board it is showing this:

    I have a tdc1000-tdc7200EVM. Please guige me in this.

    Hi,

    That EVM is designed to allows users to evaluate the operation and performance of the TDC1000 ultrasonic analog-front-end with TDC7200 time-to-digital converter, so it does not contain the ezFET circuitry necessary to program the MSP430 over USB. To program the MSP430 on this EVM, you will need to use an MSP-FET. You can use this to program the JTAG on the EVM. Again, though, this EVm is designed to allow the user to evaluate the analog front end, so the headers needed for the JTAG are not populated. You will need to populate J1 with male headers. You can see this in the schematics that are provided on the EVM product page. It also shows the header part that you can use for J1 (again, it is not populated). Once you do this, you can use the MSP-FET with these JTAG connections to program the MSP430 with CCS.

    Regards,

    Hi NathanS,

    Thank you for replying. Please clear my another doubt. Can I run the tdc7200 without the help of tdc1000 on the tdc1000-tdc7200evm? Because in my next application I need the stopwatch only and I have a evm board.

    So I was just thinking to make it without AFE but not sure.

    Thanks..

    Hi Pabel,

    It depends on your application. The tdc7200 can be used without tdc1000, but if you are working on an ultrasonic sensing application, you will most likely need the tdc1000 for the AFE. I encourage you to look at the datasheets and application notes on the product pages to see if the tdc7200 can do what you are trying to do without the AFE. Again, though, you will likely need the tdc1000.

    Regards,
    Nathan
