Compiler/TMS320C5505: fir filter dsplib

Part Number:TMS320C5505

Tool/software: TI C/C++ Compiler

Dear All,

I am trying to use the built-in cfir function in dsplib to implement the fir filter. I am using below code:

Int16 left_input;

int const h[52] = {
        -22,    -25,    -30,    -38,    -50,    -66,    -86,   -112,   -143,
        -182,   -228,   -283,   -348,   -425,   -515,   -623,   -752,   -909,
        -1103,  -1350,  -1677,  -2136,  -2838,  -4071,  -6895, -20853,  20853,
         6895,   4071,   2838,   2136,   1677,   1350,   1103,    909,    752,
         623,    515,    425,    348,    283,    228,    182,    143,    112,
         86,     66,     50,     38,     30,     25,     22
};

void main( void )
{
    signed short int left_input2 = 0

    /* Initialize BSL */
    USBSTK5505_init( );

    /* Initialize PLL */
    pll_frequency_setup(100);

    /* Initialise hardware interface and I2C for code */
    aic3204_hardware_init();
    
    /* Initialise the AIC3204 codec */
    aic3204_init();

    asm(" bclr XF");

    for ( i = 0  ; i < SAMPLES_PER_SECOND * 6000  ;i++  )
    {
        aic3204_codec_read(&left_input, &right_input); // Configured for one interrupt per two channels.

        cfir(&left_input, h, &left_input2, 0, 1, 52);

       left_output =  left_input2;

}

However, I am getting the error like

Description    Resource    Path    Location    Type
#169 argument of type "const int *" is incompatible with parameter of type "DATA *"   

Seems like there is problem in storing the coefficients of filter. I am not sure which data type should be used to store the coefficients.

Does anyone know how to store coefficients 'h' of fir filter?

Thanks and regards,
