Foshan Nationstar Optoelectronics Co., Ltd. is a national high-tech enterprise and a key high-tech enterprise of the National Torch Program under Guangdong Guangsheng, which is specialized in the research and development, production and sales of LED and LED application products. The company was founded in 1969 and began to engage in LED packaging in 1976. It is one of the earliest domestic LED manufacturers. In recent years, the company has successively undertaken more than 20 national scientific research projects such as the National "863" Plan Project, the National "863" Plan Guidance Project, the National Torch Plan Project, and the National "12th Five-Year Plan" Science and Technology Support Plan Project, and more than 80 projects below the provincial and ministerial levels. The company's products have won the titles of national and provincial key products many times, and its scientific and technological achievements have won honors such as provincial and municipal science and technology progress awards many times. Products are the foundation, and quality is the key. The company has successively passed ISO9001 quality management system certification, ISO14001 environmental management system certification, ISO/TS16949 quality management system certification, and OHSAS18001 occupational health and safety management system certification.
I am honored to have the opportunity to evaluate it. It looks pretty good. The board is relatively simple. Except for the debugger, it is a minimal system.Many friends don’t know where the information...
As the title says, in PC, you can use CImage::Load(LPCTSTR pszFileName); to read, for example: CImage img; img.Load(_T("美女.png")); HBITMAP hBmp=img.Detach(); //.... However, in WIN CE, this Load funct...
