音频DAC cs4344 驱动不起来，求助

tomyoct

自己弄了个cs4344的DAC 模块，用f4的I2S dma，发现连中断都进不了，不知道哪里出问题，请各位高手帮忙看看。

这个是cs4344的原理图，我测了一下，I2S的管脚和F4的都是通的，电源也没问题。

这个是驱动程序：
#include "CS4344.h"

u32 AudioTotalSize=0xFFFF; 
u32 AudioRemSize  =0; 
u16 *CurrentPos;           

extern void AUDIO_TransferComplete(u32 pBuffer, uint32_t Size);
void AUDIO_Init(u32 AudioFreq)
{
I2S_GPIO_Init();
Audio_I2S_Init(AudioFreq);
Audio_DMA_Init();
}

void I2S_GPIO_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOB, ENABLE);
  RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC, ENABLE);

 GPIO_InitStructure.GPIO_Pin = GPIO_Pin_12|GPIO_Pin_13 | GPIO_Pin_15 ;
 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);
  GPIO_PinAFConfig(GPIOB, GPIO_PinSource12, GPIO_AF_SPI2); 
  GPIO_PinAFConfig(GPIOB, GPIO_PinSource13, GPIO_AF_SPI2);

正点原子

参考龙源的代码:http://www.openedv.com/posts/list/5143.htm
有CS4334的.
