[AN221] Web Server I/O Remote Menggunakan DT-ARM NUC120 Board dan EMS Ethernet Module

The goal of this application is to build a system to configure and read the input/output lines on DT-ARM NUC120 Board remotely using web server. In this application, we try to use the advantage of I/O and interrupt systems of NUC120RD2BN microcontroller on DT-ARM NUC120 Board.

[AN220] Simple Web Server

In this application, we try to build a simple web server or website using EMS Ethernet Module dan DT-ARM NUC120 Board. EMS Ethernet Module acts as an ethernet controller module to bridge the communication between DT-ARM NUC120 Board (via SPI interface) with a computer network. Simple web content is stored in NUC120RD2BN's flash memory on DT-ARM NUC120 Board. The program in DT-ARM NUC120 Board is written in C language using Programmer editor and CooCox CoIDE compiler.
