  1. 您是否有“C#”或“Visual Basic”語言編寫的“USB-RELAY”代碼樣本?

    您在網站上提供的代碼僅適用於“C ++”,將很難將庫轉換為另一種編程語言。

    謝謝

    1. 暫時沒有。你可以參考C++的使用方式在C#或VB中調用dll文件。
      一,開發庫在Vistual Studio中的使用方法
      1.新建一個C ++工程
      2.在生成的stdfax.h頭文件中導入dll庫文件
         #include“usb_relay_device.h”
         #pragma comment(lib,“usb_relay_device.lib”)
      拷貝usb_relay_device.dll到你的應用程序生成目錄中

      二,開發庫函數使用方法
      調用usb_relay_init()函數初始化
      2.調用usb_relay_device_enumerate()查找插入到電腦中的所有USB免驅繼電器模塊
      調用usb_relay_device_open()打開你需要操作的設備;調用usb_relay_device_open_with_serial_number()打開指定序列號的設備
      4.其他操作:
      調用usb_relay_device_open_one_relay_channel()可以打開某路繼電器
      調用usb_relay_device_open_all_relay_channel()可以打開所有繼電器
      調用usb_relay_device_close_one_relay_channel()可以關閉某路繼電器
      調用usb_relay_device_close_all_relay_channel()可以關閉所有繼電器
      調用usb_relay_device_free_enumerate釋放內存
      調用usb_relay_exit釋放內存
