[觀點] Qualcomm QCC系列如何設定Digital Mic

客戶常常使用Digital Mic,Qualcomm QCC系列的產品預設都是Analog Mic
這篇就教你怎麼把它改成Digital Mic

1. 參考在C:/qtil/ADK_QCC512x_QCC302x_WIN_6.3.0.154/doc/subsystem_config/audio_qcc512x_qcc302x.html裡面的DigMic0PioConfig設定

162

Type

octet_string

Default

DigMic0PioConfig = [ff ff]

Allowed Values

Minimum string length

2 octets

Maximum string length

PIO configuration for first Digital Mic instance

This key defines how pins for first Digital Mic instance (instance 0) are configured. The octet string key value contains a value each for the CLK_OUT & DATA_IN signal lines in that order. Each signal can be specified to use 0x00 - 0x5F: PIO number or If the signal is not required, it should be set to 0xFF: Unused If multiple digital mic instances share the same clock pin, set the CLK_OUT signal on any one of the instances to the required PIO number and set it to Unused on all the other instances. All digital mic channels that share a clock in this way must be placed in a sync group. Also, digital mic endpoints on the instance that defines CLK_OUT should be connected first for the clock to be enabled.


2. 假設我們選擇PIO-18, PIO-19當作CLK和DATA,在subsys3_config1.htf設定如下


2. 在ADK Configuration Tool裡面設定Voice Quality和Music Quality為High Quality


3. 勾選Voice Mic 1 Digital


4. 如果要調整Mic gain,可以透過QACT在此調整


以上就大功告成了
