CEF3 ,JS to open ,read and write the computer's serial port

[wowocpp]

Hello ,I have a win32 project ,changed from cefsimple, CEF3
I want to use Java script function to open ,read and write the computer's serial port and usb port.
how can I to do this ?

Those functions are not blocked.only take a little time.
I want the functions to return values to JS

I hava read the page :https://bitbucket.org/chromiumembedded/cef/wiki/GeneralUsage
and https://bitbucket.org/chromiumembedded/ ... gration.md

I find two ways ,one way is PPAPI Plugin ,Is it the correct way to do this ?

another way is "Functions and Window Binding ",
In the render process ,implemente the function to open ,read and write the computer's serial port and usb port
by

Code: Select all

class MyV8Handler : public CefV8Handler {
public:
  MyV8Handler() {}

  virtual bool Execute(const CefString& name,
                       CefRefPtr<CefV8Value> object,
                       const CefV8ValueList& arguments,
                       CefRefPtr<CefV8Value>& retval,
                       CefString& exception) OVERRIDE {
    if (name == "myfunc") {
      // Return my string value.
      retval = CefV8Value::CreateString("My Value!");
      return true;
    }

    // Function does not exist.
    return false;
  }

  // Provide the reference counting implementation for this class.
  IMPLEMENT_REFCOUNTING(MyV8Handler);
};

Is this way correct ？ please give me some suggestions or example code and demo code

You will need to communicate with the serial port using native code in the browser process. You can then pass that information to/from JavaScript running in the renderer process as described at https://bitbucket.org/chromiumembedded/ ... t-bindings
