TDC1000-TDC7200EVM: Send output from TDC1000-TDC7200EVM using RF Modules without the use of GUI and connection between the board and a PC

Part Number: TDC1000-TDC7200EVM

Please,
Someone can give some directions how can I connect the output from TDC1000-TDC7200EVM been using to measure flow to a zigbee module without the use of GUI and connection between the board and a PC. I would like to power the EVM board using a battery. I am using the Zigbee module manufactured by DIGI ( www.digi.com/.../productdetail ). The experiment is measure the flow in some equipment in a house/apartment (sink, toilet, shower, faucet) and then send this data to a coordinator like (www.digi.com/.../connectportx2gateways) and after display the data in a PC.
Thanks,

  • Hello Sandro,

    The zigbee module can be connected to the SPI bus coming out from the MSP430 on the TDC1000-TDC7200EVM using the follow test points:

    TP19: SPI_SCLK

    TP20: SPI_MOSI

    TP21: SPI_MISO

    The CS can come from any one of the unused GPIO on the MSP430. Please reference the TDC1000-TDC7200EVM user's guide for full schematic of the EVM.

    For the software, the source code for the MSP430 firmware on the TDC1000-TDC7200EVM is included in the TDC1000-TDC7200EVM GUI download in the "Firmware" folder of the installation directory. The code for SPI reads and writes is already completed, so you will just have to adapt it for the registers of the zigbee module you are using. The MSP430 already reads in the TOF data from the TDC7200 and stores it before outputting to the GUI, so you can instead send that over SPI to the zigbee module and not have to use the PC.

    Regards,

  • Thanks ,
    I will try it and I will let you know if it worked.
