5509的 AIC23 语音芯片问题

时间:10-02 整理:3721RD 点击:

我测试了一下5509的codec程序,playmode选择为1,通过line in 输入,phone out输出声音,语音芯片为aic23,在debug的时候,点击暂停,依然会播放声音?还有如何将mcbsp的内容写到dma的rcv里面和将dma的xmt内容写到mcbsp上?如何让AIC23播放DMA的xmt里面的内容?

下面是程序代码

暂停后依然会播放声音?  要不命令没有执行, 要么是数据缓冲的问题.因为播放芯片的缓冲里还留有一定的数据可以继续播放一会

是的,暂停依然会继续播放 Line in输入的数据

命令为什么会没执行?还有就是在debug模式下,我单步调试,发现在

 /*设置AIC23的数字接口*/
 i2c_status = I2C_write( digital_audio_inteface_format,//pointer to data array
                      2,    //length of data to be transmitted
                      1,    //master or slaver

                      1,    //transfer mode of operation
                      30000   //time out for bus busy
                      );

这一步就开始播放声音了,还没有到main函数,这又是为什么?
