Connecting MSP430 of TDC1000-TDC7200EVM to Arduino

Other Parts Discussed in Thread: MSP-EXP430F5529LP

Hi everyone,
in my project i have to use a TDC1000-TDC7200EVM board in order to evaluate the distance between two piezo transducers (one is the transmitter and the other is the receiver), but i need to realize a portable device so i can't use the PC to print the distance with the GUI.
I know that i can load the firmware on the MCU with the GUI (which is simple and effective to use) so the board will work but i have to send the data to Arduino and print the TOF value on a LCD.
Can i directly communicate between the two microcontrollers? I know that GPIO4 and GPIO3 on the board cuold be used for the SPI communication, can i just connect these pins to the RX/TX pins of the Arduino and use the SPI library?
Thank you!

    Hello Luigi,

    Looking at the schematic, it appears that you could use GPIO3 and GPIO4 for UART or SPI to connect to another microcontroller. As long as both devices are using the same interface and communication, it should work. Keep in mind that you'll want to connect the GNDs too. The connector for J6 isn't populated but is for J5. The manufacturer is Samtec and the part number is SSW-107-02-G-D-RA.

    For the LCD side, you could use a MSP-EXP430F5529LP LaunchPad and one of our 430BOOST-SHARP96 LCD BoosterPack.

    Thank you, i think that i'll probably use directly the LCD on the board.
    Another question, when i use the GUI it will create a new folder with the ccs code, am i right?
    In order to integrate the LCD i have to modify the code that the GUI has created (adding the part of the code that integrate the LCD) and then load it on the MCU?

    Yes, that's correct.
