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.
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
