es8388 record no voice #14

Closed lloovve closed 5 years ago

lloovve commented 5 years ago

i use this code, play wav file is ok,but record no voice? need help

Vonger commented 5 years ago

this bug is because es8328 driver did not update register 0x03 correctly. microphone bias did not enabled. once we record audio it change 0x03 from 0xfc to 0x0c but this 0x0c should be 0x00. I will looking into this later.

i try this work for few days ,maybe this bug we shuld work on register ES8328_DACCONTROL21(reg 43) slrck lrck_sel ES8328_ADCCONTROL3 (reg 11) TRI

ES8328_DACCONTROL21=0x80 ES8328_ADCCONTROL3=0x00 ASDOUT has i2s date out ,but rec flie paly is noise

I use a simple logic analyser do this. I tried your register, looks like it work more or less, at least switch is all on, but noise output it should be some volume control is not turned to max

maybe help

I have bought esp32-lyrat ,hope some help to do this

Vonger commented 5 years ago

actually once I make it work, 20170527 version, but not using es8328 driver, directly hard coded into driver.

03 0c -> 03 00 0d 22 -> 0d 33(272) 18 22 -> 18 33 19 24 -> 19 20

After fix the upper register, it works But es8328 driver modify the registers to default...so still need to code and understand the driver to make it work ;)

es8399_slave_mode

I noticed that es8388 datasheet ,slave mode not support 272 Ratio ,and es8388 in slave mode will auto detect MCLK/LRCK ratio.

i change es8388 as master mode and 7688 slaver mode rec is ok, so the problem is above

not that problem. I can record normally now, later I will submit patch.

Vonger commented 5 years ago

emm, still have noise use master mode..

Vonger commented 5 years ago

works normal now, closed
