Display module for wireless embedded communication system

This paper presents a practical implementation of a custom wireless access point with display module to view the communication and configuration parameters. For the display module we design a hierarchy menu system, with control buttons that enable the user to scroll to specific types of information and select between parameters. The display module is very useful for embedded systems with limited resources because it offers status information about connected users, ROM/RAM usage, IP address, connection types, transfer rates, bandwidth, etc. without the need to enter the configuration menu using web interface.
