    Hello Thomas,

    Code:

                    uint8_t idx;
                    uint8_t temp;
            
                    sRegWrite(0,0x02,0x00);//"Standby Request" //"Powerdown Request" All to 0, normal mode.
                    LOG_INFO("PCM5121: PCM5121 Read 0x02 = %02x.... \r\n",Pcm5121_ReadByte(0x02));
                    sRegWrite(0,0x04,0x00);
                    sRegWrite(0,0x0e,0x10);
                    //sRegWrite(0,0x0d,0x10);
                    sRegWrite(0,0x0d,0x00);
                    sRegWrite(0,0x0e,0x30);


                    for (idx = 0; idx < 7; idx++){
                                    sRegWrite(0, pllcfg_96[idx][0],pllcfg_96[idx][1]);
                    }

                    sRegWrite(0,0x25,0x1a);

                    LOG_INFO("PCM5121: PCM5121 Read 0x25 = %02x.... \r\n",Pcm5121_ReadByte(0x25));
                    
                    sRegWrite(0,61,0x30);
                    sRegWrite(0,62,0x30);
                    
                    //sRegWrite(0,0x3D,0x1F);  //gain
                    //sRegWrite(0,0x3E,0x1F);

                    printf("PCM5121: PCM5121 Read 0x5B = %02x.... \r\n",Pcm5121_ReadByte(0x5B));
                    Pcm5121_WriteByte(0x00,0x00);
                    printf("PCM5121: PCM5121 Read 0x5E = %02x.... \r\n",Pcm5121_ReadByte(0x5E));
                    Pcm5121_WriteByte(0x00,0x00);
                    printf("PCM5121: PCM5121 Read 0x5F = %02x.... \r\n",Pcm5121_ReadByte(0x5F));
                    LOG_INFO("PCM5121: PCM5121 init success.... \r\n");

    result:

    Hello,

    I am not clear what is the specific ask here?  Can you please let me know what your question is?

    If you want to discuss some registers, would you please send me in the simple format such as

    W   device_ID   Reg   Value  ( all in HEX)

    and if you are reading any register in question please give me the reg number and the value it is reading.

    Regards,

    Arash
