音频codec es8374问题

sss
 
MJPEG
 
音频接口
 
目前用到一款芯片es8374，现在一直不通。设计是这样的：由LIN2输入，MONOOUT输出，
主控这边设置为48k采样，16bit。 主控做master，8374做slave。芯片的设置怎么设置，有调试过的兄弟帮个忙，谢谢  [img]D:\InsertPic_(08-23-21-54-38).png[/img]

最后的问题在那里，我也遇到这个片子了，也是没有一点反应，片子的i2c地址，CE拉低，感觉是整个i2c命令通道没有调通，海思部分，该做的都尝试了，连个杂音也没出。

经过查找资料，最后我这边卡在了，i2c的地址，使用开源的i2ctool，编译到3536C上运行，得到的i2c-0总线上的ES8374地址为0x22（CE引脚拉高，如果拉低，是0x20,看文档自己算出来时7bit 0x10,但实际不对，所以控制通信出了问题，一旦通信正常，驱动装载时，就可以听到咔嚓一声）

下面是最关键的驱动部分代码

void soft_reset(unsigned int chip_num)
{
        //soft reset
        printk("soft_reset in chip_num:%d addr:0x%x\n",chip_num,IIC_device_addr[chip_num]);

        ES8374_write(IIC_device_addr[chip_num],0x00,0x03); //IC Rst stop
        ES8374_write(IIC_device_addr[chip_num],0x01,0x7F); //IC clk on
        ES8374_write(IIC_device_addr[chip_num],0x02,0x08);  //select PLL

我这边已经出声音了，主要是i2c的地址没对，总以为是7bit，0x10,实际在作驱动es8374.ko时，是CE引脚拉高时，这个地址是0x22,如果拉低，这个地址是0x20,主要通过i2cTools开源工具里面的i2cdetect探测,./i2cdetect -y -r 0 ，得到了i2c-0总线上面的这个设备的确切地址，然后不停修改es8374.ko的代码，不停通过rmmod es8374以及insmod es8374.ko，从而确定是否开启音频，一旦开启成功，虽然没有注入i2s音频流，喇叭也会咔嚓响一下的，然后在到应用层，按照海思的方法，开启相应音频接口即可。

3536C部分：寄存器，我配置了这些，有些可能不合适，但至少出声音了，注意是代功放的speak out通道出声音了，估计驱动还没开line out，暂时还没音：

这个是我修改的驱动源码：
最主要的2个函数，我修改了一下tlv320的源码生成的，然后调整了一下结构，毕竟2中片子功能部分有差异，我没有用原来的配置方法，所以直接把整个结构导入，这样在驱动内部一次性按照配置，一下都执行了

海思MPI应用层主要就是配置Es8374AudioPara结构体，然后调用如下函数即可：

    if (s_fdES8374 < 0)
    {
        printf("SetAudioCodecPara can't open ES8374:%s\n",ES8374_FILE);
        return;
    }
    printf("SetAudioCodecPara open ES8374,%s fd:%d\n", ES8374_FILE,s_fdES8374);
    printf(PRINTF_WARNING"SetAudioCodecPara:\nbStartMic:%d\n bStartLineIn:%d\n bMicLoopOut:%d\n bLineInLoopOut:%d\n nMicVolume:%d\n nLineInVolume:%d\n nLineOutVolume:%d\n bStartLineOut:%d\n nSpeakOutVolume:%d\n bStartSpeakOut:%d\n"PRINTF_NONE,Es8374AudioPara.bStartMic,Es8374AudioPara.bStartLineIn,Es8374AudioPara.bMicLoopOut,Es8374AudioPara.bLineInLoopOut,Es8374AudioPara.nMicVolume,Es8374AudioPara.nLineInVolume,Es8374AudioPara.nLineOutVolume,Es8374AudioPara.bStartLineOut,Es8374AudioPara.nSpeakOutVolume,Es8374AudioPara.bStartSpeakOut);

回复的有点乱了，主要是每次修改要审核，以为没成功，结果发了一堆，删除也没法及时体现，不太习惯。有几个回复，没有意义，重复了。看的时候，忽略即可。

MIC以及LINE in 输入音量太小，寄存器是0x21,不能开启LDCM 否则输入的音量非常小，

ES8374_write(IIC_device_addr[chip_num],0x21,0x34); 这个配置是可以的
