Using DLog_1Ch from C

Other Parts Discussed in Thread: CONTROLSUITE

Hi, 

I'm working with the F28035 explorer kit and I'm trying to use the DLog_1Ch module from the digital power library. I have no asm files in my project and I can't figure out how to compile my stuff. I always end up with an undefined symbol. DLog_1Ch.asm is in my project. I included dplib.h from my main C file. 

extern volatile long *DLOG_1ch_Input1;
volatile int32 loggedValue;

DLOG_1ch_Input1 = &loggedValue;

This is what I have left trying to compile it. DLOG_1ch_Input1 always end up being undefined... I looked at the project PFC2PhiL which is using the Dlog module but it's using it from assembly... Is it a must?

Thanks!

    For documentation on Digital Power Library refer to

    controlSUITE\libs\app_libs\digital_power\f2803x_v3.3\Doc

    For this module from digital power library a C-Assembly framework is essential,

    We have another datalog buffer module used in Motor Control application, that can be used from a C ISR

    Please Look at the reference example located at

    \development_kits\HVMotorCtrl+PfcKit_v2.0\HVACI_Sensorless

    Hi
    I am using F28335
    I want to see the graph variables in CCS v6, my code is:
    befor main:
    DLOG_1CH_F dlog_1ch1;
    float32 DBUFF_1CH1[300];
    float32 dval1;

    in main:
    DLOG_1CH_F_init(&dlog_1ch1);
    dlog_1ch1.input_ptr = &dval1; //data value
    dlog_1ch1.output_ptr = &DBUFF_1CH1[0];
    dlog_1ch1.size = 100;
    dlog_1ch1.pre_scalar = 5;
    dlog_1ch1.trig_value = 1;
    dlog_1ch1.status = 2;

    in ISR code

    dval1= (Vd);
    DLOG_1CH_F_FUNC(&dlog_1ch1);
    DLOG_1CH_F_MACRO(dlog_1ch1);
    I runed the project, but the graph of (Vd) is incorrect
    Can you help me please?
