瑞芯微读取寄存器_瑞芯微Android软件中添加ALC5640 音频CODEC 的寄存器修改

1、/sys/kernel/debug/asoc/RK29_RT3224/rt3261.0-001c/codec_reg --> write: echo '寄存器 值' > codec_reg

--> read: cat codec_reg

2、/proc/driver/rt3261_ts --> write func: echo 'w:寄存器 =值，寄存器=值，... ' > rt3261_ts

--> read func: echo 'r:寄存器，寄存器，...' > rt3261_ts

3、ALC5640有2种寄存器，一般寄存器(MX /RNG),私有寄存器(PR /RNI)

RNG直接写即可：i2cwrite(0x65,0x0C00);[EX:地址65h写0C00h]

RNI需要间接写：i2cwrite(0x6A,0x003D);i2cwrite(0x6C,0x3400);[EX:地址3DH写3400H]

4、读取index reg：cat /sys/devices/platform/rk30_i2c.0/i2c-0/0-001c/index_reg
