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的内置ADC和PWM，实现录音和播放。
- 前面的文章已经详细讲述了ADC+DMA的配置. 这里重点讲PWM+DMA的配置. 我们的目的是用PWM作为DAC, 来播放音乐
- 为了达到这个目标，首先需要在STM32上调通PWM+DMA的测试, 比如输出单音信号(do 293Hz, so 440Hz).
- 通过听音, 以及逻辑分析抓波形的方式来进行分析
- 我们的开发板是STM32H750-ARTPI，环境是rt-thread+cherryusb
1. TIM12(TRGO)+TIM5(PWM)+DMA的CubeMX配置
这里先讲一个折腾过程中遇到的问题, 以了解这个问题的背景
- 最初, 我是用定时器级联+DMA+传输/半传输中断填充dma buffer实现播放音乐。TIM3设置为主定时器, TIM5设置为从定时器。具体来说，我用TIM3产生16kHz UG event，去触发TIM5的pwm（160kHz载波）。DMA设置的是TIM5，选择Circular mode。hdma_tim5_ch3.Init.Request = DMA_REQUEST_TIM5_CH3。我本来预期的是，每16kHz改变一次TIM5 pwm的占空比。实际情况是，每160kHz（每个pwm波形结束）都会改变占空比，这就有问题了。也就是说，每个DMA请求不是受TIM3 16kHz控制，而是受TIM5 160kHz控制，这肯定不对。
- 为了解决这个问题，我引入了DMA的同步机制，通过DMA请求同步定时器，来实现每16kHz改变一次占空比。我发现TIM5的DMA不接收TIM3的TRGO同步，它可以接收TIM12的TRGO，于是我开启了TIM12的TRGO，确实实现了效果。
- 这个时候重新审视发现，其实TIM3没有起到应有的作用，完全没有必要用。于是我去掉了TIM3，只用TIM5+TIM12。TIM5产生160kHz的PWM，TIM12产生16kHz的TRGO用于触发DMA请求，效果是一样的。
- 这一顿折腾的结果，就是下面给出的方案
CubeMX配置方法
TIM5选择内部时钟, 使能CH3-PWM(ARTPI-P2排针上PA2)
TIM5参数配置, Period配置1499(对应PWM频率=240MHz/1500=160kHz, 也就是载波频率)，开启Auto-Reload功能，Pulse（也就是占空比）配置为750(50%占空比)。关于为什么选160kHz载波频率，后面有详细说明。
配置DMA后DMA中断使能默认开启。开启TIM5中断，虽然不确定是否需要，但是为了保险起见，还是开启了。(事实上从后面对HAL_TIM_PWM_Start_DMA函数的Trace分析来看，没有开启任何TIM的中断。因此这里没有必要打开TIM5的NVIC中断使能)
DMA配置，开启TIM5_CH3通道，选择Memory to Peripheral模式，使能循环模式，使能DMA请求同步定时器，选择TIM12_TRGO作为同步信号。
开启DMA Fifo，因为TIM5是32bits计数器，因此Data Width只能选择word，FiFo只能选择Full。选择Burst Size为4 beats，在Memory侧。
- 配置TIM12参数, 使能TRGO, 选择Update Event作为TRGO信号。period为14999，对应TRGO频率为240MHz/150000=16kHz。这个频率就是与UAC匹配的音频的采样率。
2. main.c程序关键点说明
- 特别注意, dac_buffer用于DMA改变TIM5的CCR3. 由于STM32H7的TIM5是32bits计数器, 因此CCR3是32bits的。因此dac_buffer的类型是uint32_t.
- 产生440Hz的正弦波, 采样频率是16kHz, 因此点数是16kHz/440Hz=36 pts
- sin_table也是uint32_t类型的
#define TONE_FREQ (440)
#define SIN_TABLE_SIZE (16000 / TONE_FREQ) /*16kHz/440Hz=36 pts*/
uint32_t sin_table[SIN_TABLE_SIZE];
USB_NOCACHE_RAM_SECTION USB_MEM_ALIGNX uint32_t dac_buffer[SIN_TABLE_SIZE * 2]; // Double buffer for DMA
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] = (uint32_t)((sin(angle)*0.95 + 1.0f) * 749.5f); // 12-bit DAC, 0-1499 range
}
}
static void fill_dac_buffer(void)
{
for (int i = 0; i < SIN_TABLE_SIZE; i++)
{
dac_buffer[i] = sin_table[i];
dac_buffer[i + SIN_TABLE_SIZE] = sin_table[i];
}
}
- TIM12用于同步DMA的request generator, 控制PWM改变CCR3的频率(对应音频采样率), 本例程需要为16kHz
- 由于TIM12挂在APB1上, 时钟频率=120x2=240MHz，因此产生16kHz的TRGO需要分频240MHz/16000=15000, 于是设置Prescaler=0, 即不分频。设置Period=14999，对应实际Period=14999+1=15000
htim12.Instance = TIM12;
htim12.Init.Prescaler = 0;
htim12.Init.CounterMode = TIM_COUNTERMODE_UP;
htim12.Init.Period = 14999;
htim12.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
htim12.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE;
if (HAL_TIM_Base_Init(&htim12) != HAL_OK)
{
Error_Handler();
}
- TIM5挂在APB2上, 时钟频率=120x2=240MHz, 因此产生160kHz的PWM需要分频240MHz/160000=1500, 于是设置Prescaler=0, 即不分频。设置Period=1499, 对应实际Period=1499+1=1500。
- 为什么需要160kHz频率？因为这个是PWM载波频率，需要不能被人耳听到，因此频率越高越好，实际只要大于44.1kHz人耳应该就听不到了。为了保险起见，这里取是16kHz的10倍，也就是160kHz，此时Period=1500，也就是PWM占空比的取值范围是0-1499，仍然有大于10bits的精度，这个可以产生比较好的音质了。
- 当然，如果降低160kHz到80kHz也是可以的，此时Period=3000, 占空比的取值范围是0-2999，有超过11bits的精度。
htim5.Instance = TIM5;
htim5.Init.Prescaler = 0;
htim5.Init.CounterMode = TIM_COUNTERMODE_UP;
htim5.Init.Period = 1499;
htim5.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
htim5.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_ENABLE;
if (HAL_TIM_Base_Init(&htim5) != HAL_OK)
{
Error_Handler();
}
- TIM5 PWM模式的2个回调函数，分别如下。可以用于Circular DMA模式实现连续不断喂数据。
- 为了方便逻辑分析仪抓时序，我们初始化了一个GPIO，用于打点。
void HAL_TIM_PWM_PulseFinishedCallback(TIM_HandleTypeDef *htim)
{
if (htim->Instance == TIM5)
{
HAL_GPIO_TogglePin(GPIOG, GPIO_PIN_11);
}
}
void HAL_TIM_PWM_PulseFinishedHalfCpltCallback(TIM_HandleTypeDef *htim)
{
if (htim->Instance == TIM5)
{
HAL_GPIO_TogglePin(GPIOG, GPIO_PIN_11);
}
}
- 主函数
int ADC_TIM5_DMA_Init(void)
{
MX_DMA_Init();
MX_ADC1_Init();
MX_TIM2_Init();
MX_TIM5_Init();
MX_TIM12_Init();
generate_sin_table();
fill_dac_buffer();
adc_sem = rt_sem_create("adc_sem", 0, RT_IPC_FLAG_FIFO);
adc_thread = rt_thread_create("adc_thread",
adc_data_thread_entry,
RT_NULL,
4096,
20,
10);
rt_thread_startup(adc_thread);
HAL_TIM_Base_Start(&htim2);
HAL_TIM_Base_Start(&htim12);
HAL_ADC_Start_DMA(&hadc1, (uint32_t *)adc_buffer, ADC_BUFFER_SIZE * 2);
HAL_TIM_PWM_Start_DMA(&htim5, TIM_CHANNEL_3, (uint32_t *)dac_buffer, SIN_TABLE_SIZE * 2);
return 0;
}
INIT_APP_EXPORT(ADC_TIM5_DMA_Init);
- 发现了一个问题(bug)，就是ADC的ClockPrescaler不能是ADC_CLOCK_ASYNC_DIV1, 必须用至少ADC_CLOCK_ASYNC_DIV2，否则工作异常。
- 虽然这个问题不属于PWM+DMA，但比较重要，不得不提醒一下。
hadc1.Instance = ADC1;
hadc1.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV2; /*这里ADC_CLOCK_ASYNC_DIV1输出异常, 必须用至少ADC_CLOCK_ASYNC_DIV2*/
hadc1.Init.Resolution = ADC_RESOLUTION_16B;
hadc1.Init.ScanConvMode = ADC_SCAN_DISABLE;
hadc1.Init.EOCSelection = ADC_EOC_SINGLE_CONV;
hadc1.Init.LowPowerAutoWait = DISABLE;
hadc1.Init.ContinuousConvMode = DISABLE;
hadc1.Init.NbrOfConversion = 1;
hadc1.Init.DiscontinuousConvMode = DISABLE;
hadc1.Init.ExternalTrigConv = ADC_EXTERNALTRIG_T2_TRGO;
hadc1.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_RISING;
hadc1.Init.ConversionDataManagement = ADC_CONVERSIONDATA_DMA_CIRCULAR;
hadc1.Init.Overrun = ADC_OVR_DATA_PRESERVED;
hadc1.Init.LeftBitShift = ADC_LEFTBITSHIFT_NONE;
hadc1.Init.OversamplingMode = DISABLE;
hadc1.Init.Oversampling.Ratio = 1;
if (HAL_ADC_Init(&hadc1) != HAL_OK)
{
Error_Handler();
}
3. 测试效果
测试293Hz频率ok（对应D调的do音）
测试440Hz频率ok（对应D调的so音）
这里的波形是293Hz的。我们设置DMA长度为2个sin完整波形的长度。PWM+DMA每遇到传输半完成，和传输完成中断，就会翻转一下GPIO。
因此GPIO翻转的时间=DMA点数x1/16kHz=(16kHz/293Hz)x(1/16kHz)=1/293Hz=3.413ms。这个与测试基本吻合。
可以看到PWM载波频率是160kHz，大约过10个点就改变一次占空比
4. 总结
- PWM + DMA播放音乐的方案，不能采用定时器级联的方案，主要是DMA搞不定。需要使用DMA request同步的方案。
- TIM5+TIM12的组合, 其中TIM5作为PWM, TIM12作为TRGO, 触发DMA的同步。
- TIM5频率配置为160kHz, 精度超过10bits。TIM5频率配置为16kHz。
- 需要特别注意，TIM5是32bits定时器，因此它的CCRx的数据位宽（包括DMA的数据位宽），都要使用32bits。
- 另外发现了一个ADC配置的bug，就是时钟prescaler不能使用1分频，最少必须2分频。

7. 附录3：TIM5 + DMA关键函数Trace分析(jlink trace)
- 对如下2个关键函数进行Trace分析
HAL_TIM_PWM_Start_DMA(&htim5, TIM_CHANNEL_3, (uint32_t *)dac_buffer, SIN_TABLE_SIZE * 2)
/**
* @brief This function handles DMA1 stream1 global interrupt.
*/
void DMA1_Stream1_IRQHandler(void)
{
/* USER CODE BEGIN DMA1_Stream1_IRQn 0 */
/* USER CODE END DMA1_Stream1_IRQn 0 */
rt_base_t level = rt_hw_interrupt_disable();
HAL_DMA_IRQHandler(&hdma_dac1_ch2);
rt_hw_interrupt_enable(level);
/* USER CODE BEGIN DMA1_Stream1_IRQn 1 */
/* USER CODE END DMA1_Stream1_IRQn 1 */
}
- HAL_TIM_PWM_Start_DMA
- 从这个函数的trace可以看出，这个函数会调用HAL_DMA_Start_IT函数，这个函数会配置DMA参数并使能DMA中断。这个函数会调用TIM_CCxChannelCmd配置TIM的通道参数。
- 从这个函数的trace可以看出，这个函数并没有开启任何TIM的中断, 因此确实不需要开启TIM的NVIC中断。
