windows系统下CC2530超声波控制步进电机开启关闭

以下是基于Windows系统的CC2530超声波控制步进电机的示例代码，使用了串口通信和GPIO控制：

#include <stdio.h>
#include <stdlib.h>
#include <Windows.h>
#include <conio.h>

#define BUF_SIZE 256 // 缓冲区大小
#define BAUD_RATE 9600 // 串口波特率

HANDLE hSerial; // 串口句柄
char portName[] = "COM1"; // 串口名称
unsigned char buf[BUF_SIZE]; // 接收缓冲区

int main(int argc, char* argv[])
{
    DCB dcbSerialParams = { 0 };
    COMMTIMEOUTS timeouts = { 0 };

    hSerial = CreateFileA(portName, GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
    if (hSerial == INVALID_HANDLE_VALUE)
    {
        printf("Failed to open serial port!\n");
        return 1;
    }

    // 配置串口参数
    dcbSerialParams.DCBlength = sizeof(dcbSerialParams);
    if (!GetCommState(hSerial, &dcbSerialParams))
    {
        printf("Failed to get serial port parameters!\n");
        CloseHandle(hSerial);
        return 1;
    }

    dcbSerialParams.BaudRate = BAUD_RATE;
    dcbSerialParams.ByteSize = 8;
    dcbSerialParams.StopBits = ONESTOPBIT;
    dcbSerialParams.Parity = NOPARITY;
    if (!SetCommState(hSerial, &dcbSerialParams))
    {
        printf("Failed to set serial port parameters!\n");
        CloseHandle(hSerial);
        return 1;
    }

    // 配置超时时间和缓冲区大小
    timeouts.ReadIntervalTimeout = 50;
    timeouts.ReadTotalTimeoutConstant = 50;
    timeouts.ReadTotalTimeoutMultiplier = 10;
    timeouts.WriteTotalTimeoutConstant = 50;
    timeouts.WriteTotalTimeoutMultiplier = 10;
    if (!SetCommTimeouts(hSerial, &timeouts))
    {
        printf("Failed to set serial port timeouts!\n");
        CloseHandle(hSerial);
        return 1;
    }

    // 配置 GPIO 控制引脚
    HANDLE hGPIO = CreateFileA("\\\\.\\GPIO1", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
    if (hGPIO == INVALID_HANDLE_VALUE)
    {
        printf("Failed to open GPIO device!\n");
        CloseHandle(hSerial);
        return 1;
    }

    // 配置步进电机控制引脚
    DWORD pinMask = GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_3;
    DWORD dir = GPIO_DIR_OUTPUT;
    DWORD mode = GPIO_MODE_OUTPUT_PUSH_PULL;
    if (!DeviceIoControl(hGPIO, IOCTL_GPIO_SET_PIN_MODE, &pinMask, sizeof(pinMask), &mode, sizeof(mode), NULL, NULL))
    {
        printf("Failed to configure GPIO control pins!\n");
        CloseHandle(hSerial);
        CloseHandle(hGPIO);
        return 1;
    }

    // 开始接收超声波测距数据
    DWORD bytesRead;
    while (1)
    {
        if (ReadFile(hSerial, buf, BUF_SIZE, &bytesRead, NULL))
        {
            buf[bytesRead] = 0;

            // 解析超声波测距数据
            char* ptr = strtok(buf, ",");
            int distance = atoi(ptr);
            if (distance < 100) // 超声波测距小于 100cm，则开启步进电机
            {
                DWORD state = GPIO_PIN_SET;
                if (!DeviceIoControl(hGPIO, IOCTL_GPIO_WRITE_PIN, &pinMask, sizeof(pinMask), &state, sizeof(state), NULL, NULL))
                {
                    printf("Failed to set GPIO output!\n");
                }
            }
            else // 超声波测距大于等于 100cm，则关闭步进电机
            {
                DWORD state = GPIO_PIN_RESET;
                if (!DeviceIoControl(hGPIO, IOCTL_GPIO_WRITE_PIN, &pinMask, sizeof(pinMask), &state, sizeof(state), NULL, NULL))
                {
                    printf("Failed to reset GPIO output!\n");
                }
            }
        }
    }

    CloseHandle(hSerial);
    CloseHandle(hGPIO);
    return 0;
}

代码中使用了Windows系统提供的串口通信和GPIO控制接口。通过串口接收来自CC2530超声波传感器的测距数据，当测距小于 100cm 时，开启步进电机；当测距大于等于 100cm 时，关闭步进电机。步进电机的控制引脚通过GPIO接口控制。你需要根据实际的硬件连接情况和GPIO控制方式进行相应的配置和修改。
