求助GPIO 軟體仿真

請問我現在使用GPIOC 做0 , 1輸出,
我在用keil C 軟體仿真LED1有輸出波形，但OUT1&OUT2沒有。
請問我的程序有設置錯嗎?

以下是我的程序

[mw_shl_code=c,true]#define LED1 PBout(12) #define OUT1 PCout(0) #define OUT2 PCout(1) void OutputPin_Init(void) { GPIO_InitTypeDef GPIO_InitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC|RCC_APB2Periph_GPIOB, ENABLE); GPIO_InitStructure.GPIO_Pin =GPIO_Pin_All; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_Init(GPIOC, &GPIO_InitStructure); GPIO_SetBits(GPIOC,GPIO_Pin_All); GPIO_InitStructure.GPIO_Pin =GPIO_Pin_12; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_Init(GPIOB, &GPIO_InitStructure); GPIO_SetBits(GPIOB,GPIO_Pin_12); } void Cylinder_Init(void) { TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; NVIC_InitTypeDef NVIC_InitStructure; RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM4, ENABLE); TIM_TimeBaseStructure.TIM_Period = 999; TIM_TimeBaseStructure.TIM_Prescaler =71; TIM_TimeBaseStructure.TIM_ClockDivision = 0; TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseInit(TIM4, &TIM_TimeBaseStructure); TIM_ITConfig(TIM4,TIM_IT_Update|TIM_IT_Trigger,ENABLE); NVIC_InitStructure.NVIC_IRQChannel = TIM4_IRQn; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 4; NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); //TIM_Cmd(TIM4, ENABLE); } void TIM4_IRQHandler(void) { if (TIM_GetITStatus(TIM4, TIM_IT_Update) != RESET) { TIM_ClearITPendingBit(TIM4, TIM_IT_Update ); CylinderCount++; LED1=!LED1; } } int main(void) { SystemInit(); delay_init(72); NVIC_Configuration(); OutputPin_Init(); InputPin_Init(); Cylinder_Init(); delay_ms(10); // Data_Init(); TIM_Cmd(TIM4, ENABLE); while(StartCount!=EndCount||StartCount==0) { if(lSolenoidVSTB[1]==CylinderCount-1) { OUT1=1; StartCount++; } if((lSolenoidVSTB[1]+lSolenoidVDB[1])==CylinderCount) { OUT1=0; EndCount++; } if(lSolenoidVSTB[2]==CylinderCount-1) { OUT2=1; StartCount++; } if((lSolenoidVSTB[2]+lSolenoidVDB[2])==CylinderCount-1) { OUT2=0; EndCount++; } delay_ms(1); } TIM_Cmd(TIM4, DISABLE); while(1){}[/mw_shl_code]

回复【楼主位】ChrisLiu1017:
-----------------------------
怀疑你的while循环，里面if条件没有得到满足，建议直接测试，不要去if判断了。

謝謝，原子哥回覆.
裡面if有滿足有確認了，StartCount & EndCount都有++
而且我有把OUT1 & OUT2 直接測試，也是沒有..
我直接OUT1=1; OUT2=1, delay_ms(500); OUT1=0; OUT2=0;
也沒有波形產生。
