我想寻求一些帮助 我现在在调试 I2S的接受中断 以下是我的 I2S的基本配置 /* CODEC_I2S pins configuration: WS, SCK -----------------------------*/ GPIO_InitStructure.GPIO_Pin = CODEC_I2S_WS_PIN | CODEC_I2S_SCK_PIN ; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL; GPIO_Init(GPIOB, &GPIO_InitStructure); /* Connect pins to I2S peripheral */ GPIO_PinAFConfig(GPIOB, CODEC_I2S_WS_PINSRC, CODEC_I2S_GPIO_AF); GPIO_PinAFConfig(GPIOB, CODEC_I2S_SCK_PINSRC, CODEC_I2S_GPIO_AF); /* CODEC_I2S pins configuration: SDIN -----------------------------*/ GPIO_InitStructure.GPIO_Pin =GPIO_Pin_3; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL; GPIO_Init(GPIOC, &GPIO_InitStructure); GPIO_PinAFConfig(GPIOC, CODEC_I2S_SDOUT_PINSRC, CODEC_I2S_GPIO_AF); /* CODEC_I2S pins configuration: MCK pin */ GPIO_InitStructure.GPIO_Pin = CODEC_I2S_MCK_PIN; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP; GPIO_Init(GPIOC, &GPIO_InitStructure); GPIO_PinAFConfig(GPIOC, CODEC_I2S_MCK_PINSRC, CODEC_I2S_GPIO_AF); SPI_I2S_DeInit(CODEC_I2S); I2S_StructInit(&I2S_InitStructure); I2S_InitStructure.I2S_AudioFreq = I2S_AudioFreq_48k; //I2S_Standard_PCMShort I2S_InitStructure.I2S_Standard =I2S_Standard_Phillips; //I2S_Standard_Phillips I2S_InitStructure.I2S_DataFormat = I2S_DataFormat_16b; I2S_InitStructure.I2S_CPOL = I2S_CPOL_Low; //I2S_Mode_MasterRx; I2S_InitStructure.I2S_Mode = I2S_Mode_MasterRx; I2S_InitStructure.I2S_MCLKOutput = I2S_MCLKOutput_Enable; I2S_Init(CODEC_I2S, &I2S_InitStructure); NVIC_PriorityGroupConfig(NVIC_PriorityGroup_0); NVIC_InitStructure.NVIC_IRQChannel = SPI2_IRQn; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0; NVIC_InitStructure.NVIC_IRQChannelSubPriority =1; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); I2S_Cmd(CODEC_I2S, ENABLE); SPI_I2S_ITConfig(SPI2,SPI2,SPI_I2S_IT_RXNE ,ENABLE); 就是这样配置的 但是 I2S一使能 就直接跳到 接收中断里去了 但是 我什么数据也没有 输入啊? |
