mcbsp interrupt program

Started by Unknown April 28, 2006
hey,all.I want to using the MCBSP interrupt to program.but i met some
troubles.I puzzled about the dsp/bios interrupt program. I hope someone
can give me some suggestions about my trouble.
thanks in advance.
the program follows:
#include <std.h>
#include "ex3cfg.h"
#include <csl_mcbsp.h>

extern MCBSP_Handle hMcbsp0;
extern MCBSP_Config mcbspCfg0;
Void main()
{
   CSL_init();
   CSL_cfgInit();
   MCBSP_start(hMcbsp0,MCBSP_RCV_START,0x0030);
   LOG_printf(&trace,"hello,sbs");
   return;
}
Void audio()
{
     Int in_data,out_data;
     while(!MCBSP_rrdy(hMcbsp0));
     in_data=MCBSP_read16(hMcbsp0);
     out_data=in_data&0xfffe;
     while(!MCBSP_xrdy(hMcbsp0));
     MCBSP_write16(hMcbsp0,out_data);
}
i use the MCBSP0,and set the HWI4 using the dsp/bios configration.
the complile is ok,but the loaded program in the board is nothing.

Getting interrupts to work with the DSP/BIOS can be a little bit tricky. There is a sample application on TI's website that may be of help. I believe it is titled something along the lines of "running applications from flash memory". While the app note isn't necessarilly what you are after, it does provide both a bios and non bios working example of using interrupts. One thing I did notice, however, is that you stated that you used HWI14. At the very bottom of the BIOS configuration is a a section for configuring PIE Block interrupts. Try using those instead.
