本文介紹在QCC5171下切換Equalizer的測試過程。

測試工具

MDE：MDE_WIN_2.8.0.37_x64

Toolkit：ADK Toolkit 1.2.13.21_x64

QACT：NULL

Bluesuite：NULL

Hardware：Qualcomm QCC5171 DEV.

Software：adk-src-1-0_qtil_standard_oem_qcc517x-qcc307x，ADK-22.3-CS-r00344.1 0.0.344.1 headset

Here we go

切換EQ的最終調(diào)用函數(shù)為：OperatorsStandardSetUCID(peq_op,0x00);

其中ucid這個參數(shù)就是這里的：

上面第一組是off，第二、三、四、五、六組為固定EQ，第七為user EQ。

設(shè)置EQ可以通過本地事件觸發(fā)，也可以通過gaia，gaia就直接通過app進(jìn)入到Equalizer選項進(jìn)行設(shè)置即可。

本地事件觸發(fā)在headset_test.c中有一個測試函數(shù)：

這里的參數(shù)就一個preset，就是上面截圖中的UCID，如果是User EQ則直接輸入preset=0x3f，如果是其他EQ，則輸入preset = UCID-1，比如需要選擇Rock這組，則可以直接輸入：

apps1.fw.call.appTest_MusicProcessingSetPreset(1)

實際測試下來，

通過appTest_MusicProcessingSetPreset來設(shè)置EQ，其log如下：

如果要對設(shè)置EQ過程中做一些其他操作的話，可以參考上面的log來分析代碼。
