写一个基于stm32使用AD控制jr6001语音模块播放不同音频的库函数

以下是一个基于STM32的AD控制JR6001语音模块播放不同音频的库函数示例代码：

#include "stm32f10x.h"

#define AD_CHANNEL GPIO_Pin_0
#define AD_PORT GPIOA
#define JR6001_PORT GPIOB
#define JR6001_DATA_PIN GPIO_Pin_0
#define JR6001_CLK_PIN GPIO_Pin_1
#define JR6001_RST_PIN GPIO_Pin_2

void jr6001_init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);

    GPIO_InitStructure.GPIO_Pin = JR6001_DATA_PIN | JR6001_CLK_PIN | JR6001_RST_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(JR6001_PORT, &GPIO_InitStructure);

    GPIO_ResetBits(JR6001_PORT, JR6001_RST_PIN);
    GPIO_SetBits(JR6001_PORT, JR6001_RST_PIN);

    GPIO_ResetBits(JR6001_PORT, JR6001_DATA_PIN);
    GPIO_SetBits(JR6001_PORT, JR6001_DATA_PIN);

    GPIO_ResetBits(JR6001_PORT, JR6001_CLK_PIN);
    GPIO_SetBits(JR6001_PORT, JR6001_CLK_PIN);
}

void jr6001_send_cmd(uint16_t cmd)
{
    int i;

    GPIO_ResetBits(JR6001_PORT, JR6001_CLK_PIN);
    GPIO_SetBits(JR6001_PORT, JR6001_DATA_PIN);

    for (i = 0; i < 16; i++) {
        if (cmd & 0x8000) {
            GPIO_SetBits(JR6001_PORT, JR6001_DATA_PIN);
        } else {
            GPIO_ResetBits(JR6001_PORT, JR6001_DATA_PIN);
        }
        cmd <<= 1;
        GPIO_SetBits(JR6001_PORT, JR6001_CLK_PIN);
        GPIO_ResetBits(JR6001_PORT, JR6001_CLK_PIN);
    }
}

void jr6001_play_sound(uint16_t sound)
{
    jr6001_send_cmd(0x7F00 | sound);
}

uint16_t read_adc(void)
{
    ADC_InitTypeDef ADC_InitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;
    uint16_t ad_value;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_ADC1, ENABLE);

    GPIO_InitStructure.GPIO_Pin = AD_CHANNEL;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_Init(AD_PORT, &GPIO_InitStructure);

    ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
    ADC_InitStructure.ADC_ScanConvMode = DISABLE;
    ADC_InitStructure.ADC_ContinuousConvMode = DISABLE;
    ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_NbrOfChannel = 1;
    ADC_Init(ADC1, &ADC_InitStructure);

    ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_55Cycles5);

    ADC_Cmd(ADC1, ENABLE);
    ADC_SoftwareStartConvCmd(ADC1, ENABLE);

    while (!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));

    ad_value = ADC_GetConversionValue(ADC1);

    ADC_Cmd(ADC1, DISABLE);
    ADC_DeInit(ADC1);

    return ad_value;
}

int main(void)
{
    jr6001_init();

    while (1) {
        uint16_t ad_value = read_adc();

        if (ad_value < 100) {
            jr6001_play_sound(1);
        } else if (ad_value < 200) {
            jr6001_play_sound(2);
        } else {
            jr6001_play_sound(3);
        }
    }
}

在这个示例代码中，我们首先定义了JR6001语音模块的端口和引脚，然后实现了一个JR6001初始化函数和一个发送命令函数。主函数中我们使用了一个ADC来获取输入的模拟电压值，并根据不同的电压值调用不同的JR6001播放音频的函数。
