CCS/MSP430F5528: LDOPWR Driver Lib API

Raghav Ringshia

Part Number: MSP430F5528
Other Parts Discussed in Thread: MSP430F5310, MSP430WARE,

Tool/software: Code Composer Studio

I'm trying to use the LDOPWR API with driver Lib, even when I use the provided examples, I get these errors:

"../main.c", line 54: warning #225-D: function "LDOPWR_unLockConfiguration" declared implicitly
"../main.c", line 54: error #20: identifier "LDOPWR_BASE" is undefined

4 errors detected in the compilation of "../main.c".
gmake: *** [main.obj] Error 1
gmake: Target 'all' not remade because of errors.

How do I solve this issue, I do not have problems with other API's.

    Hi, 

    I ran the same project as you did, and it still did not work.

    Hi, I try to build the project again and the building is finished. My CCS version is 9.2 and compiler version is TI.v18.12.3. Thanks!

    Hi, 

    I'm on CCS v10.1.0 and compiler version is Ti 20.2.1.LTS. None of the LDOPWR examples or self written functions are successfully built or debugged, the errors I mentioned before are persistent. 

    thanks, 
    Raghav

    Hi Raghav

    I try the project building on CCS v10.1 which is the same with your platform. The build is finished normally.

    According to the errors information from you. some function and micro definition is abnormal. I checked the project, the functions are defined on ldopwr.c file and msp430f5310.h file (I select the target device as F5310)

    the directory of ldopwr.c is msp430ware_3_80_11_07\driverlib\driverlib\MSP430F5xx_6xx

    the directory of msp430f5310.h is ccs1010\ccs\ccs_base\msp430\include

    I attached these 2 files as the reference. Please check if there are the same files on your CCS folder. Thanks!

    HI, 

    Both the files you referred to are In the correct directory. Just to confirm, I'm using the MSP430F5528 and not the MSP430F5310 like you are.

    Thanks,

    Raghav

    When I add the project again from DriverLib but this time using the MSP430F5310 like yours, it complies. It only does not work for MSP430F5528.

    THANKS, 
    Raghav

    Hi Raghav,

    The MSP430F531x doesn't have USB, while the MSP430F552x does. However, while the USB functionality is completely disabled in F531x, the one thing that is still enabled is the LDO, which is why they have some register compatibility.

    These are the LDO registers in F531x:

    And for F552x:

    As observed, the LDOPWRCTL is in the same place as USBPWRCTL, and if you check the register description, you'll see that a lot of the registers will be the same, but not all.

    So, my first question would be if you are planning to use USB? If you aren't, maybe you could consider the F531x or F532x families.

    If you are planning to use USB, we recommend to use the USB library, which I think uses some of these registers and might cause conflicts if you want to handle it externally.

    But if you are still interested in enabling the LDOPWR  DriverLib in F552x, maybe you could try copy-pasting the register definition from the F5329 header file into your msp430FF5529.h:

    I honestly can't say that I recommend this, since the register definition of both devices is different (i.e. USBPWRCTL.SLDOEN is available and initialized to 1 after reset for F5529, but LDOPWRCTL.LDOEN resides in the same location and it's is not available and it's initialized to 0 after reset in F5329). But I think it could build and maybe you could modify it to meet your needs.

    Regards,

    Luis R
