最近在了解ST MEMS麦克风的使用，有一个Audio_playback_and_record的工程，我的目的是想了解一下处理音频数据的过程，但是发现 int main()里找不到waverecorder.c文件中定义的函数 ，而且主函数中还多了加速度传感器的内容，让我很是疑惑，小白学艺不精，请问有大佬可以回答我下吗 主程序如下 /** - @brief Main program
- @param None
- @retval None / int main(void) { / STM32F4xx HAL library initialization:
- Configure the Flash prefetch, instruction and Data caches
- Configure the Systick to generate an interrupt each 1 msec
- Set NVIC Group Priority to 4
- Global MSP (MCU Support Package) initialization */ HAL_Init();
/ Configure LED3, LED4, LED5 and LED6 / BSP_LED_Init(LED3); BSP_LED_Init(LED4); BSP_LED_Init(LED5); BSP_LED_Init(LED6); / Configure the system clock to 168 MHz / SystemClock_Config(); / Initialize MEMS Accelerometer mounted on STM32F4-Discovery board / if(BSP_ACCELERO_Init() != ACCELERO_OK) { / Initialization Error / Error_Handler(); } MemsID = BSP_ACCELERO_ReadID(); / Turn ON LED4: start of application / BSP_LED_On(LED4); / Configure TIM4 Peripheral to manage LEDs lighting / TIM_LED_Config(); / Initialize the Repeat state / RepeatState = REPEAT_ON; / Turn OFF all LEDs / LEDsState = LEDS_OFF; / Configure USER Button / BSP_PB_Init(BUTTON_KEY, BUTTON_MODE_EXTI); /##-1- Link the USB Host disk I/O driver ##################################/ if(FATFS_LinkDriver(&USBH_Driver, USBDISKPath) == 0) { /##-2- Init Host Library ################################################/ USBH_Init(&hUSB_Host, USBH_UserProcess, 0); /##-3- Add Supported Class ##############################################/ USBH_RegisterClass(&hUSB_Host, USBH_MSC_CLASS); /##-4- Start Host Process ###############################################/ USBH_Start(&hUSB_Host); / Run Application (Blocking mode)/ while (1) { switch(AppliState) { case APPLICATION_START: MSC_Application(); break; case APPLICATION_IDLE: default: break; } / USBH_Background Process / USBH_Process(&hUSB_Host); } } / TrueStudio compilation error correction / while (1) { } }
