[Communication-Mobile] AN10859_NXP DL : 0: 恩智浦官方例程，附有中文说明，适合学习。(This software was adapted to work with a Keil MCB1700 board and the Keil RV ARM C-Compiler with as few modifications as possible. Note that modifications are not optimal, because ARM is a 32-bit machine while the original software was written for 16-bit cpu. The web page shows the values of two analog inputs (AN0 and AN1). This tiny webserver needs very little resources and therefore has some restrictions: - only one active TCP session at any one time - no support for fragmented IP datagrams - no buffer for TCP datagrams received in wrong order - only one web page. No GIF/JPG graphics possible. The IP address can be modified in the module tcpip.h to fit into your existing LAN (see MYIP_x). Please order the extra issue 'Embedded Internet' of the 'Design & Elektronik' magazine for a technical description. It is only available in German language.)
