问一个用uV4的软件Simulator Debug的问题

steven7522

今天我在学习Timer这一节，我也照着书上写的想用Simulator来看一看波形。但是当我打开软件上的示波器后，按照书中的方法加入想观察的信号名的时候，软件提示我未定义的信号名，有谁可以告诉我这是怎么回事？怎么解决，谢谢

解决了，是我自己选择目标芯片的时候选错了。

另一个问题，我将Fire的程序改了改，将TIM3改到了TIM5，从手册上看4个Channel应该是PA0~PA3，我的程序如下：
void TIM5_GPIO_Config(void)
{
        GPIO_InitTypeDef GPIO_InitStructure;
        RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM5, ENABLE);
        RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

        GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_2 | GPIO_Pin_3;
        GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
        GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
        GPIO_Init(GPIOA, &GPIO_InitStructure);
}

void TIM5_PWM_Config(void)
{
        TIM_TimeBaseInitTypeDef TIM_TimeBaseStrcuture;
        TIM_OCInitTypeDef TIM_ODInitStructure;

        uint16_t CCR1_Val = 500;
        uint16_t CCR2_Val = 400;
        uint16_t CCR3_Val = 200;
        uint16_t CCR4_Val = 100;
       
        TIM_TimeBaseStrcuture.TIM_Period = 999;
        TIM_TimeBaseStrcuture.TIM_Prescaler = 0;
        TIM_TimeBaseStrcuture.TIM_CounterMode = TIM_CounterMode_Up;
        TIM_TimeBaseStrcuture.TIM_ClockDivision = TIM_CKD_DIV1;
        TIM_TimeBaseInit(TIM5, &TIM_TimeBaseStrcuture);

        TIM_ODInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
        TIM_ODInitStructure.TIM_OutputState = TIM_OutputState_Enable;
        TIM_ODInitStructure.TIM_Pulse = CCR1_Val;
        TIM_ODInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
        TIM_OC1Init(TIM5, &TIM_ODInitStructure);
        TIM_OC1PreloadConfig(TIM5, TIM_OCPreload_Enable);

        TIM_ODInitStructure.TIM_OutputState = TIM_OutputState_Enable;
        TIM_ODInitStructure.TIM_Pulse = CCR2_Val;
        TIM_OC2Init(TIM5, &TIM_ODInitStructure);
        TIM_OC2PreloadConfig(TIM5, TIM_OCPreload_Enable);

        TIM_ODInitStructure.TIM_OutputState = TIM_OutputState_Enable;
        TIM_ODInitStructure.TIM_Pulse = CCR3_Val;
        TIM_OC3Init(TIM5, &TIM_ODInitStructure);
        TIM_OC3PreloadConfig(TIM5, TIM_OCPreload_Enable);

        TIM_ODInitStructure.TIM_OutputState = TIM_OutputState_Enable;
        TIM_ODInitStructure.TIM_Pulse = CCR4_Val;
        TIM_OC4Init(TIM5, &TIM_ODInitStructure);
        TIM_OC4PreloadConfig(TIM5, TIM_OCPreload_Enable);

        TIM_ARRPreloadConfig(TIM5, ENABLE);
        TIM_Cmd(TIM5, ENABLE);
}

现在的实验现象是从软件的Simulator上看到的4个信号是4条直线，没有电平的变化。请问我的程序中有什么问题吗？谢谢
