接IN3R/IN3L 录制出来的pcm 没有声音,请问需要注意哪些寄存器配置呢?
aic3204_write(IIC_device_addr[num], 0, 1 ); // Select page 1
aic3204_write(IIC_device_addr[num], 52, 0x04); //IN3L is routed to Left MICPGA with 10K resistance
aic3204_write(IIC_device_addr[num], 55, 0x04); //IN3R is not routed to Right MICPGA
aic3204_write(IIC_device_addr[num], 54, 0x03); // CM is routed to Left MICPGA via CM2L with 40K resistance
aic3204_write(IIC_device_addr[num], 57, 0xC0); // CM is routed to right MICPGA via CM2L with 40K resistance
aic3204_write(IIC_device_addr[num], 59, 0x80); // MIC_PGA_L unmute
aic3204_write(IIC_device_addr[num], 60, 0x80); // MIC_PGA_R unmute
aic3204_write(IIC_device_addr[num], 0, 0); // Select page 0
aic3204_write(IIC_device_addr[num], 81, 0xa0); // Powerup Left and Right ADC
aic3204_write(IIC_device_addr[num], 82, 0x4); // Unmute Left and Right ADC
Amy Luo:
您好,
请参考下面文档中4.0.4和4.0.5章节配置寄存器,我看您写的寄存器值与要实现的注释中的功能好多都不一致,所以请比对寄存器每一位的功能定义来确定寄存器值

Hi Amy Luo,
参考了4.04 和4.05 章节, 完整的配置 我有在论坛里提问, 具体的链接地址:https://e2echina.ti.com/question_answer/analog/audio/f/42/t/200251,
