MPU9250 with MSP430F5529LP

Other Parts Discussed in Thread: MSP430F5529, MSP430F5528

Hi,

I am using MSP430F5529LP with Emsensr MPU9250 breakout board. And I am using Invensense Embedded motion driver 6.12 and doing this connections. But I am getting some errors in Code Composer Studio. I doubt there may be some wrong connections or some jumper configuration problem. But I don't know the correct jumper configuration and where to find it. I would really be appreciated with your helps. 

MPU9250 MSP430
SDA -> P4.1
SCL -> P4.2
VDD -> 3.3V
VDDI -> 3.3V
INT -> p1.6

Is this set up correct?

Best regards,

    Hi Ugur!

    When getting errors in CCS, this is independent from your hardware connections. What does CCS say? P4.1 and P4.2 can be used for I²C when using port mapping. And don't forget the common GND for both.

    Hi Dennis,

    Thank you very much for your kind reply.

    Yes, I connect MSP430's GND pin to MPU9250 breakout board's GND pin.

    Then first of all, I take "error #20: identifier "UPCS0" is undefined " then I chance UPCS0 with UCLKSEL0 then this error has been solved.

    After that, when I enter properties and select MSP430F5529 it produces error 10099-D "./lnk.cmd", line 48: error #10099-D: program will not fit into available memory. placement with alignment fails for section ".text" size 0x2b12 . Available memory ranges:
    FLASH size: 0x1000 unused: 0xe56 max hole: 0xe56

    I enter optimization in properties and select higher level of optimization choice in release mode but there is no change.

    How can I solve this error?

    Best regards,

    There are two I2C connections in MSP430F5529. Motion driver has declared to use the other set. The pins are:

    SCL -> P3.1
    SDA ->P3.2
    INT -> P2.0
    VDD ->3.3V
    GND ->GND

    I did these connections and it worked.

    Hey Saumya ,
    I am using trying to interface MPU9250 with the MSP430F5529 and I am using Invensense Embedded motion driver 6.12 for this. Do I have to make any changes while using the libraries mentioned in motion driver 6.12 as it is made for MSP430F5528 and not MSP430F55229 moreover I am getting the error :

    make: cmd.exe: Command not found eMD-6.0 C/C++ Problem

    I am using the configuration you mentioned. Can you please help?
