你好,我现在遇到一个问题,我可以采集到芯片内部发出的数据,但是采集不到麦克风的输入信号
这是我驱动里面寄存器的配置
tlv320aic31_write(IIC_device_addr[chip_num],3,0x91);
tlv320aic31_write(IIC_device_addr[chip_num],4,0x20);
tlv320aic31_write(IIC_device_addr[chip_num],5,0x1E);
tlv320aic31_write(IIC_device_addr[chip_num],6,0x00);
tlv320aic31_write(IIC_device_addr[chip_num],7,0x00);
tlv320aic31_write(IIC_device_addr[chip_num],8,0xf0);
tlv320aic31_write(IIC_device_addr[chip_num],9,0x00);
tlv320aic31_write(IIC_device_addr[chip_num],11,0x01);
tlv320aic31_write(IIC_device_addr[chip_num],19,0x80);
tlv320aic31_write(IIC_device_addr[chip_num],24,0x80);
tlv320aic31_write(IIC_device_addr[chip_num],25,0x40);
tlv320aic31_write(IIC_device_addr[chip_num],51,0x08);
tlv320aic31_write(IIC_device_addr[chip_num],65,0x08);
tlv320aic31_write(IIC_device_addr[chip_num],101,0x00);
附件里面是我的原理图用的是第10和11口,项目已经卡在这里两个星期了,希望您帮帮我!!!! QQ:978472426
