CCS/BQ76PL455A-Q1: main code sys_main.c information

Part Number: BQ76PL455A-Q1

Tool/software: Code Composer Studio

hello sir/Mam,

           I wish to work with bq76pl445. I downloaded all related software to it when I get to see the main code there are many functions like nSent = WriteReg(nGrp_ID, 3, 0x62, 1, FRMWRT_GRP_R); and nRead = ReadReg(nDev_ID, 12, &wTemp, 1, 0); I want to learn this code from scratch to write on my own. What are the values that are being passed in that function?

    Hi Revathi,

    Thanks for the question! In CCS using the example code, If you right click on any function and click 'open declaration' you will be taken to the c file that declares the function and the variables that are being passed into it. For WriteReg this is located in the pl455.c file and requires 5 values (device ID, register address, data, byte length, and write type).

    Best Regards,

    Taylor

    Hi Taylor,

     Thank you for your answer. But I have another question where can I learn these functions to write code? Is there any driver libraries as you were given for F2837xD_DriverLib_Users_Guide?Thank you in advance.

    Hello Taylor,

        I thank you heartfully I got the answer to my question and now I even know those functions. This is my last question regarding this I am getting an error when building the code.

    The error is : 

    Trouble parsing include or instance XML file
    C:\ti\ccsv7\ccs_base\common\targetdb\..\Modules\hercules\CP15_CortexR4F_r1p3.xml (The system cannot find the path specified)

     How can I fix this? I have searched all the folders for that file that doesn't work...

    Hope I get an answer to this question too...

    Thank you.
