Is the parallel resistor in the crystal oscillator a damping resistor? Reduce the amplitude?
Connecting R in series causes the output frequency to be too high?
Is there any problem with what is said a...
Part of the code is as follows: IWebBrowser2 *m_pBrowser; HRESULT hr; IDispatch* pHtmlDocDispatch = NULL; IHTMLDocument2 * pHtmlDoc = NULL; IHTMLWindow2 * p = NULL; hr = m_pBrowser->get_Document(&pHtm...
