3）调试流程： ①主控制器： 工程图片：
初始化： delay_init();
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
uart_init(115200);
LED_Init();
KEY_Init();
LCD_Init();
Adc_Init();
TIM3_Init(1666,7199);
W25QXX_Init();//初始化W25Q128
my_mem_init(SRAMIN);//初始化内部内存池
exfuns_init();//为fatfs相关变量申请内存
f_mount(fs[0],"0:",1);//挂载SD卡
f_mount(fs[1],"1:",1);//挂载FLASH.
LCD_Display_Dir(1);
主控制器LCD显示（显示简单的做了一下，另外照片画质太差请见谅）
ADC采样值左侧显示，并以图形显示当前所处档位。 LED状态右侧显示，LED灭右侧框内为白色，LED闪烁框内会有绿色方块闪烁，LED常亮对应位置绿色方块常亮。
无法显示汉字，增加字库之后：
ADC初始化： void Adc_Init(void)
{
ADC_InitTypeDef ADC_InitStructure;
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA |RCC_APB2Periph_ADC1 , ENABLE ); //使能ADC1通道时钟
RCC_ADCCLKConfig(RCC_PCLK2_Div6); //设置ADC分频因子6 72M/6=12,ADC最大时间不能超过14M
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN; //模拟输入引脚
GPIO_Init(GPIOA, &GPIO_InitStructure);
ADC_DeInit(ADC1); //复位ADC1,将外设 ADC1 的全部寄存器重设为缺省值
ADC_InitStructure.ADC_Mode = ADC_Mode_Independent; //ADC工作模式:ADC1和ADC2工作在独立模式
ADC_InitStructure.ADC_ScanConvMode = DISABLE; //模数转换工作在单通道模式
ADC_InitStructure.ADC_ContinuousConvMode = DISABLE; //模数转换工作在单次转换模式
ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None; //转换由软件而不是外部触发启动
ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right; //ADC数据右对齐
ADC_InitStructure.ADC_NbrOfChannel = 1; //顺序进行规则转换的ADC通道的数目
ADC_Init(ADC1, &ADC_InitStructure); //根据ADC_InitStruct中指定的参数初始化外设ADCx的寄存器
ADC_Cmd(ADC1, ENABLE); //使能指定的ADC1
ADC_ResetCalibration(ADC1); //使能复位校准
while(ADC_GetResetCalibrationStatus(ADC1)); //等待复位校准结束
ADC_StartCalibration(ADC1); //开启AD校准
while(ADC_GetCalibrationStatus(ADC1)); //等待校准结束
// ADC_SoftwareStartConvCmd(ADC1, ENABLE); //使能指定的ADC1的软件转换启动功能
}
直接在主函数中循环读取AD值： Adc_Val=Get_Adc_Average(ADC_Channel_1,100);
将AD值显示在LCD上，并计算出相应的长度，以图形显示在屏幕上： LCD_ShowxNum(150,140,Adc_Val,4,24,0);//显示ADC的值
Adc_X = 1.0*261 * Adc_Val / 4095;
