使用Python控制hid继电器

import ctypes
import os
import time

current_dir = os.path.dirname(os.path.abspath(__file__))
ctypes.CDLL(os.path.join(current_dir, "hidapi.dll"))

# 接下来可以继续使用hid模块
import hid

# 定义 HID 设备的厂商 ID 和产品 ID，需要根据实际继电器修改
VENDOR_ID = 0x5131 #0x140b #
PRODUCT_ID = 0x2007 #0x7d7 #

try:
    #ret = hid.enumerate(VENDOR_ID, PRODUCT_ID)
    #print(ret)
    #for device_info in hid.enumerate():
    #    print(device_info)
    # 打开 HID 设备
    device = hid.Device(vid=VENDOR_ID, pid=PRODUCT_ID)
    print("成功连接到 HID 继电器")
    # 示例：发送命令打开继电器（命令需要根据实际继电器协议修改）
    open_command = bytes([0x00,0xa0,0x01,0x01,0xa2] + [0x00]* 60 )  # 调整命令格式以适应你的设备
    print(f"Sending command: {open_command.hex()}")
    device.write(open_command)
    print("已发送打开继电器命令")
    # 尝试读取设备响应
    try:

        print(f"Received response: {response}")
        #response_str = response.decode('utf-8')
