Hi,
I am working with TMS320C6711 DSK with CCS 2.10.00 I am trying to send a sine-wave through SPEAKER-OUT ... and although the following code does not make any errors, it does not work ... Do you know, where my problem is ... Do you have a similar program, that sends and receives data, especially if it works with BSL-functions ... Please send my any test programs, which run under c6711dsk, especially those about codec ad535...because I really need help... Thanks in advance mb //Source code =================================================================== #include <bsl.h>/* BSL headers */ #include <csl.h>/* CSL headers */ #include <bsl_ad535.h>/*AD535-Modul-Header */ #include <c6711dsk.h> /* #include <c6x.h> // C6000 compiler definitions header #include <c6x11dsk.h> // C6000 DSK definitions header */ #include <csl_mcbsp.h> // Multichannel serial port header #include "dc_conf.h" #include <math.h> /*um sin() aufrufen zu knen */ #include <stdlib.h /*************************************** * Definitions ****************************************/ #define SAMPLE_FREQ 8000.0 #define SIZE_TABLE 256 /*************************************** * Global variables ****************************************/ double x[SIZE_TABLE]; int lauf; AD535_Handle hAD535; //handle-variable for codec //Uint32 controlRegVal3,controlRegVal4,controlRegVal5; AD535_Config my_AD535_Config = { AD535_LOOPBACK_DISABLE, AD535_MICGAIN_ON, AD535_GAIN_0DB, AD535_GAIN_0DB }; /*************************************** * Functions ****************************************/ void codec_init(void) { /* Use BSL routines to open , reset, and configure the codec */ hAD535 = AD535_open(AD535_localId); AD535_reset(hAD535); AD535_config(hAD535, &my_AD535_Config); //MCBSP_setfree(0); }// END of codec_init() -------------------- void sine_init(void) //initialisiert die tabelle mit werten { for(lauf=0;lauf<SIZE_TABLE;lauf++) x[lauf]=0.0; for(lauf=0;lauf<SIZE_TABLE;lauf++) x[lauf]= sin(2*PI*lauf/SIZE_TABLE); }// END of sine_init() -------------------- /*###################################### * Main routine ----------------------- ######################################*/ void main() { /* Local variables */ /* Initialize the chip support library, required */ CSL_init(); /* Initialize the board support library, required */ BSL_init(); /* Open and configure the local codec */ codec_init(); /*zum Nachpren, wie Controlregister d.
