Part Number: TDC1000
Other Parts Discussed in Thread: MSP430F5528, , MSP430FR6047,

Hello,

What MCU is suit for TDC1000??ex:89S51 or others.

    Hello Robert,

    If a microcontroller is needed to measure the time of flight based on the TDC1000 outputs, the timing capabilities of the microcontroller are the most important feature that needs to be considered.

    In general, however, the TDC1000 can operate with any microcontroller that offers SPI communication, or even ones that don't as long as you can program the GPIO to behave as an SPI port.

    There are two main evaluation modules for the TDC1000 that use different TI microcontrollers:

    TDC1000-TDC7200EVM uses the MSP430F5528: www.ti.com/.../tdc1000-tdc7200evm

    TDC1000-C2000EVM uses the C2000-TMS320F28035PAG: www.ti.com/.../tdc1000-c2000evm

    Hello Scott,

     

    Thanks for reply promptly.

    I want the features which can auto recognize and measure velocity of air and water .

    1. How about TDC1000-Q1 use the MSP430FR6047 ?

    2. TDC1000-Q1 Max. and Min. of measuring distance in Air and Water?

    3. Where can download free source code and circuit for reference?

    4. Is free or charge of the developer’s kit?

     

    Sincerely,

    Hi Robert,

    1. That MSP430 would work fine with the TDC1000.
    2. Minimum distance depends on the frequency used to drive the sensor, and the sensor itself. The maximum time measured is 8ms, which is about 1.2m in air, and 5.6m in water.
    3. The full schematic for the TDC1000-TDC7200EVM is included in the user's guide (www.ti.com/.../sniu021a.pdf) and the firmware for the MSP430 on the EVM is included with the GUI download (www.ti.com/.../tdc1000-tdc7200evm)
    4. The EVM is $75 (linked above), but all of the reference material for the EVM (including full schematic and firmware) is available free of charge.

    Regards,
