STM32控制SYN6288的软件设计

首先，需要明确SYN6288是一款语音识别芯片，可以通过串口与STM32进行通信。因此，需要在STM32上设计串口通信的程序。

以下是一份简单的代码示例：

#include "stm32f10x.h"

#define SYN6288_RX_BUF_SIZE 128

char syn6288_rx_buf[SYN6288_RX_BUF_SIZE];
uint8_t syn6288_rx_index = 0;

void USART1_IRQHandler(void) {
  if (USART_GetITStatus(USART1, USART_IT_RXNE) != RESET) {
    char rx_data = USART_ReceiveData(USART1);

    if (syn6288_rx_index < SYN6288_RX_BUF_SIZE) {
      syn6288_rx_buf[syn6288_rx_index++] = rx_data;
    }
  }
}

void syn6288_send_cmd(const char* cmd) {
  USART_ITConfig(USART1, USART_IT_RXNE, DISABLE);

  while (*cmd) {
    USART_SendData(USART1, *cmd++);
    while (USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET)
      ;
  }

  USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);
}

void syn6288_init() {
  GPIO_InitTypeDef GPIO_InitStructure;
  USART_InitTypeDef USART_InitStructure;
  NVIC_InitTypeDef NVIC_InitStructure;

  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, ENABLE);

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

  USART_InitStructure.USART_BaudRate = 9600;
  USART_InitStructure.USART_WordLength = USART_WordLength_8b;
  USART_InitStructure.USART_StopBits = USART_StopBits_1;
  USART_InitStructure.USART_Parity = USART_Parity_No;
  USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
  USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
  USART_Init(USART1, &USART_InitStructure);

  USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);

  NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);

  USART_Cmd(USART1, ENABLE);
}

int main() {
  syn6288_init();

  // 发送指令
  syn6288_send_cmd("AT+SSPEECH=0\r\n");

  while (1) {
    // 处理接收到的语音识别结果
    if (syn6288_rx_index > 0) {
      // 处理 syn6288_rx_buf
      syn6288_rx_index = 0;
    }
  }
}

在上述代码中，我们使用了 USART1 进行串口通信。通过 `syn6288_init` 初始化串口，并通过 `syn6288_send_cmd` 发送指令。在 `USART1_IRQHandler` 中，我们可以处理接收到的语音识别结果。
