TAS5711 Slave 模式如何設定2.1聲道程序
时间：10-02

請問一下,我目前用了一個DSP+5711的方案,以DSP為Matser,5711為slave模式,看了Design Guide內容的部分,依照參數下去,聲音都沒有輸出,附上我的程式碼檔案,能否告知是哪個環節出了問題,謝謝
你好：
1.你的原理图连接是否正确？可以对照我们的EVM板检查连接。
2.没有声音输出的时候，看一下电感前面是不是50%占空比的PWM波形，开关频率是不是384Khz。
3. 2.1的软件设置主要是0x05寄存器改成0x84或0x8C.
兄弟 你的问题解决了吗 我用的tas5508 也是没出声 可以讨论下吗Q273203365
我是依照你們EVB板的原理圖去製作的，我現在遇到的問題是2.1模式程式不知道修改什麼地方，我附件中的程序在2.0 BD模式是有聲音輸出的，如你所說，我是只要去修改0x05這邊就好了嗎？還是還有什麼地方也需要修改，煩請告知
我的5508在 2.0也是出声了 现在研究 怎么 分频 让左右声道各输出高低音 初涉音频 感觉好难
Hi Flora;
現在聲音都出來了,不過我有發現另一個問題,就是我在線路上預留的2.0與2.1的切換,可是目前我的軟件寫的是2.1模式,但是怎麼我的4個輸出接口都會有聲音輸出,另外下列是我的代碼,現在發現2.1模式狀態下,低音的效果都沒出來,是不是我哪邊有沒寫到或是寫錯,麻煩請幫我確認下
