python hid完整代码

在Python中，使用hid库操作HID（Human Interface Device）设备的基本流程如下，这里提供了一个简化的示例，展示如何连接、读取和关闭设备：

import hid

# 找到第一个可用的HID设备
device = hid.enumerate()
vendor_id = device['vendor_id']
product_id = device['product_id']
serial_number = device.get('serial_number', 'Unknown')

print(f"Found HID device: Vendor={vendor_id}, Product={product_id} (Serial={serial_number})")

# 打开设备
try:
    device_handle = hid.open(vendor_id, product_id)
except Exception as e:
    print(f"Error opening device: {str(e)}")
    exit(1)

# 获取设备描述符
try:
    descriptor = device_handle.read(hid.HID_DEVICE_SIZE)
except hid.Error as e:
    print(f"Error reading descriptor: {str(e)}")
    device_handle.close()
    exit(1)

# 遍历输入报告并打印
for report in descriptor[4:]:
    input_report = {
        "id": report,
        "data": list(report[1:])
    }
    print(f"Input Report ID: {input_report['id']} Data: {input_report['data']}")

# 关闭设备
device_handle.close()
