0. 概述
- 文本目标基于Cherryusb官方例程audio_v1_mic_speaker_multichan_template.c，底层对接STM32的SAI驱动wm8978音频模块, 实现录音和播放。
- SAI的配置比较复杂, WM8978的配置更为复杂, 需要注意的点较多. 我们需要把这个过程进行分解，一步一步来。
- 为了达到这个目标，首先需要在STM32上调通SAI+DMA的收发测试, 比如输出单音信号(do 293Hz, so 440Hz), 然后将SD_A与SD_B短接, 将音频回环到输入, 通过DMA采集后打印出来。通过这种方式可以不依赖于任何设备(逻辑分析仪, 音频模块), 测试SAI的基本收发功能。类似的SPI/UART也可以这么测试。
- 当然，我们手头有几个不需要配置, 拿来即用, 直接可以接收标准i2s信号的音频模块(PCM1808 ADC, PCM5102A DAC), 可以方便的用来测试SAI的输入输出功能。这样可以通过听音和录音来测试。
- 逻辑分析仪抓一下波形，可以核对数据收发是否正确，MCLK/BCLK/FS频率是否正确
- 我们的开发板是STM32H750-ARTPI，环境是rt-thread+cherryusb
1. SAI+DMA的CubeMX配置
STM32H750-ARTPI的SAI接口通过P1排针引出, 使用的是SAI2
开启SAI2，配置A通道为TX(带MCLK输出)，B通道为同步RX。所谓同步的意思是B通道自己不产生时钟, 而是来自A通道的时钟, 与A通道同步。
勾选I2S/PCM模式
配置A通道，每一项要仔细检查。A通道为异步，因为它是要输出时钟源的，它是发起者，不需要与其它时钟同步。
基本参数是：16kHz采样率，2个slot(左右声道)，每个slot 16bits。Mclk不要分频，不要过采样。
对于这样一个配置，FS=16kHz, MCLK=256FS=4.096MHz，BCLK=2x16x16kHz=512kHz
配置B通道，每一项要仔细检查。B通道为同步，它采用与A通道相同的时钟，因此是同步的。
B通道的参数配置简单一些，与A通道基本相同
配置A通道的DMA，有了之前的经验，很容易配置这里的参数。因为A通道为TX，所以Burst设置在Memory侧。
配置B通道的DMA，有了之前的经验，很容易配置这里的参数。因为B通道为RX，所以Burst设置在Peripheral侧。
SAI2的全局中断勾选上，不清楚是否需要，后面通过trace分析一下。（大部分外设使用DMA的时候，只使用DMA的中断，不使用外设的中断，但也有少数的情况。比如STM32H7 ADC需要通过ADC自身中断服务函数清楚过载中断标志）
引脚配置，与ART-PI保持一致
SAI2时钟的配置，这里需要比较精细。目标4.096MHz
2. main.c程序关键点说明
- 先用293Hz (D调的do) 的标准正弦波测试
- 我们先创建sin_table数组作为音源，由于我们定义的sine_table是uint16_t类型，因此满量程范围是0-65535范围, 幅度取0.95FullScale
- 因为有左右声道，所以每个点需要重复两次, 填入dac_buffer
#define TONE_FREQ (293)
#define SIN_TABLE_SIZE (16000 / TONE_FREQ) /*16kHz/293Hz=55 pts*/
// Add before ADC_DAC_DMA_Init function
static void generate_sin_table(void)
{
for (int i = 0; i < SIN_TABLE_SIZE; i++)
{
float angle = 2 * M_PI * i / SIN_TABLE_SIZE;
sin_table[i] = (uint16_t)((sin(angle)*0.95 + 1.0f) *32767.5f); // 16bits, 0-65535 range
}
}
static void fill_dac_buffer(void)
{
for (int i = 0; i < SIN_TABLE_SIZE; i++)
{
dac_buffer[2*i] = sin_table[i];
dac_buffer[2*i + 1] = sin_table[i]; /*repeat填充*/
}
}

- 初始化函数
- 初始化SAI和DMA，生成sin_table数组，填充dac_buffer数组
- 以DMA的方式启动SAI2_A和SAI2_B通道，即录音和播放同时进行
- 将SD_A与SD_B引脚短接起来，形成音频回环。程序设计的是，Rx DMA接收一轮后就停止工作，然后打印数据，将数据导入excel表绘图

3. 测试效果
293Hz正弦波，逻辑分析仪抓到的I2S波形。可见一个完整的293Hz数据周期是3.387ms，基本符合预期（1/293Hz=3.413ms)
我们可以看到左右声道的数据是一致的
FS信号的频率16kHz
BCLK信号的频率512kHz
MCLK信号的频率4.096MHz
将音频回环的数据(也就是录音的数据)通过串口发送出来，并plot，可见是一个完美的正弦波
- PCM5102A DAC播放293Hz频率ok（对应D调的do音）
- PCM5102A DAC播放440Hz频率ok（对应D调的so音）
4. 总结
- SAI + DMA的播放音乐的方案，是最正宗，最标准的方案。音质最好。
- 这种方案，SAI的配置是难点。通过CubeMX配置，仔细检查每一项。尤其是MCLK的生成，典型MCLK=256FS。
- 先播放标准正弦波，通过逻辑分析仪抓波形，确认MCLK/FS/BCLK/DATA都符合预期
- 然后通过听音测试。推荐使用不要配置的I2S音频模块，比如PCM5102A模块，方便测试。

7. 附录3：SAI + TX + RX + DMA关键函数Trace分析(jlink trace)
- 对如下4个关键函数进行Trace分析
HAL_SAI_Receive_DMA(&hsai_BlockB2, (uint8_t *)adc_buffer, ADC_BUFFER_SIZE * 2);
HAL_SAI_Transmit_DMA(&hsai_BlockA2, (uint8_t *)dac_buffer, SIN_TABLE_SIZE * 2);
/**
* @brief This function handles DMA1 stream2 global interrupt.
*/
void DMA1_Stream2_IRQHandler(void)
{
/* USER CODE BEGIN DMA1_Stream2_IRQn 0 */
/* USER CODE END DMA1_Stream2_IRQn 0 */
rt_base_t level = rt_hw_interrupt_disable();
HAL_DMA_IRQHandler(&hdma_sai2_a);
rt_hw_interrupt_enable(level);
/* USER CODE BEGIN DMA1_Stream2_IRQn 1 */
/* USER CODE END DMA1_Stream2_IRQn 1 */
}
/**
* @brief This function handles DMA1 stream3 global interrupt.
*/
void DMA1_Stream3_IRQHandler(void)
{
/* USER CODE BEGIN DMA1_Stream3_IRQn 0 */
/* USER CODE END DMA1_Stream3_IRQn 0 */
rt_base_t level = rt_hw_interrupt_disable();
HAL_DMA_IRQHandler(&hdma_sai2_b);
rt_hw_interrupt_enable(level);
/* USER CODE BEGIN DMA1_Stream3_IRQn 1 */
/* USER CODE END DMA1_Stream3_IRQn 1 */
}
- HAL_SAI_Transmit_DMA
- 从这个函数看, 配置DMA并开启DMA中断
- 另外, 它开启了SAI的中断__HAL_SAI_ENABLE_IT(hsai, SAI_InterruptFlag(hsai, SAI_MODE_DMA)), 最终开启了SAI_IT_OVRUDR(溢出中断)和SAI_IT_WCKCFG(时钟配置错误中断)。这说明, SAI在CubeMX配置的时候，确实应该打开SAI全局中断。
Continuing.
