我這里有一個工程，同時要使能AIC3204的ADC和DAC，IIS總線接的是6748，這里雙向包養違法通訊我們之前檢測是沒有題目的。AIC3204電路如下
我們今朝數字電子訊號從DIN輸出后，LOL和LOR有模仿電子訊號輸入。AIN-1、AIN+1模仿電子訊號輸出，可是DOUT數字電子訊號一向沒反映。我改了好幾遍偏置一向沒啥反映請ti的工程師了解一下狀況是不是哪里設置裝備擺設的有題目。

• 請問AIC3204的IN1L/IN1R到HPL/HPR的銜接無法斷開嗎？168
從您供給的代碼和描寫來看，您曾經勝利地初始化了AIC3204的ADC和DAC效能。可是，您提到DOUT數字電子訊號沒有反映。這能夠是由于以下幾個緣由：
1. 時鐘設置裝備擺設題目：請確保您的I2S總線時鐘設置裝備擺設對的。AIC3204需求一個穩固的時鐘輸出來正常任務。您需求檢討您的時鐘設置裝備擺設，確保它知足AIC3204的請求。
2. 數據格局題目：請檢討您的數據格局能否對的。AIC3204支撐多種數據格局，如I2S、左對齊和右對齊等。您需求確保您的數據格局與AIC3204的請求相婚配。
3. 偏置設置裝備擺設題目：您提到曾經測驗考試修正偏置，但依然沒有反映。請檢討您的偏置設置裝備擺設能否對的。AIC3204的偏置設置裝備擺設觸及到多個存放器，如PGA、ADC和DAC的偏置等。您需求確保這些存放器的設置裝備擺設對的。
4. 硬件銜接題目：請檢討您的硬件銜接能否對的。確保AIC3204的DIN、DOUT、LRCLK和BCLK引腳與您的I2S總線銜接對的。
5. 軟件題目：請檢討您的軟件代碼能否對的。確保您的代碼對的地初始化了AIC3204，并對的地處置了數據傳輸。
以下是一些提出的調試步調：
1. 應用示波器檢討I2S總線上的電子訊號，確保時鐘和數據電子訊號正常。
2. 應用邏輯剖析儀檢討I2S總線上的數據傳輸，確保數據格局對的。
3. 應用I2C調試東西檢討AIC3204的存放器設置裝備擺設，確保偏置設置裝備擺設對的。
4. 檢討硬件銜接，確保一切包養網dcard引腳銜接對的。
5. 慢慢調試您的軟件代碼，確保數據傳輸對的。
盼望這些提出能輔助您處理題目。假如題目依然存在，請供給更多具體信息，以便我們進一個步驟剖析。
