TDC1000-TDC7200EVM: sending the Tof measurement data to arduino through uart.

Part Number: TDC1000-TDC7200EVM

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 Pabel,

    You will need to write some code to perform the UART transactions between the MSP430 on the TDC1000-TDC7200EVM and your arduino. On the MSP430F5528 pins P4.4 and P4.5 are used as UART TX and RX respectively. Those pins are available on the EVM via GPIO3 and GPIO4 which can be accessed at vias on the top left of the board.

    You will need to update the firmware source code that is included with the TDC1000-TDC7200EVM GUI in the install directory under the Firmware folder.

    There are currently no examples on how to use UART communication to transfer data from the TDC1000-TDC7200EVM to another microcontroller. The engineers in the MSP430 forum (e2e.ti.com/.../), or the CCS forum (e2e.ti.com/.../) may be able to help you better with your implementation if you have a specific question. In that case, start a new thread and choose the MSP430F5528 or CCS as the part number for the thread.

    I am also notifying a colleague of this thread. If you encounter a problem with your UART implementation, he may be able to help.

    Regards,

    Thank you Scott for replying.

    I will create a new thread for that. My another doubt is, can I use the evm for distance measurement in air,in an open field and i will use rf transmitter and receiver.

    For that, can I use it directly by connecting tx/rx pins of sensor to tdc1000-tdc7200evm tx/rx pins ? Or I need to program the evm for it.  

    Thanks

    Hi Scott,

    can you answer the previous question please.....

    The TDC1000/TDC7200EVM is not designed for use with RF transmitters. The TX pin will output a square wave with a programmable number of pulses at the frequency the user selects. The voltage swing is from 0.3V to VDD-0.3V. If that satisfies the requirements of the sensor you are using, then it could work, but I have no experience with this application and cannot guarantee it will work.
