c - 端口不发送输出

Question

我不明白为什么，尽管调用了该函数并且尽管适当地设置和清除了这些位，但当按下/未按下开关时，PWM 既不工作也不 LED 闪烁。我正在为这个项目使用Atmega 328 微控制器。这些是使用的以下代码。

主程序

#include <avr/io.h>
#include "gpio.h"
#include "DoorLock_ver_2.h"
#include "adc.h"
#include "PWM.h"
int is_locked;
int main(void)
//copy this main() to proteus
{

    //unsigned int bit:1;
    // Insert code
      GPIOConfig(PD1,OUTPUT);
      GPIOConfig(PD2,OUTPUT);
      GPIOConfig(PD3, INPUT);
      GPIOConfig(PD4, INPUT);
      GPIOConfig(PD5, OUTPUT);
      GPIOConfig(PD6,OUTPUT);
      int s=0,r=0;
    while(1)
    {
        s=SpeedAssess();
        r=RemoteCtrl();
        if(s==1)
        {
            PWM(1);//JUST TESTING for locking
            is_locked=1;
        }
        else {
            if(r==1){
                PWM(1);//for locking
                AutomaticWindow(1);
                is_locked = 1;
            }
            else{
                //for unlocking
                PWM(0);
                AutomaticWindow(0);
                is_locked = 0;
            }
        }
    }
    return 0;
}

DoorLock_ver_2.c

#include<avr/io.h>
#include<util/delay.h>
#include "gpio.h"
#include "adc.h"
#include "PWM.h"
#include "DoorLock_ver_2.h"


short int SpeedAssess(){
    //check if speed is greater than 20kmph and sends signal to lock the door
    
    if (GPIOPinRead(PD4)){
        return 1;
    }
    else{
        return 0;
    }
}
short int RemoteCtrl(){
    //on pressing the button, lock the door
    if (GPIOPinRead(PD3)){
        //AutomaticWindow(0);
        return 0;
    }
    else {
        //AutomaticWindow(1);
        return 1;
    }
}
void AutomaticWindow(short int f){

    //closes window automatically when vehicle is locked(lock button is pressed on remote)
    if(f==1)
    {
        GPIOPinWrite(PD2,HIGH);
        GPIOPinWrite(PD1,HIGH);
    }
    else
    {
        GPIOPinWrite(PD2,LOW);
        GPIOPinWrite(PD1,LOW);

    }
}

我为 Atmega328 制作了一个 GPIO api，因为他们坚持让我们这样做，我无法使 API 对所有端口都有效，所以它特定于微控制器的端口 D

我也在使用 proteus 工具进行模拟设置。这是我玩模拟后它达到的唯一状态。 仿真工具的最终状态，即使点击开关也不会改变。点击链接查看图片

我哪里错了？请帮忙。
