This application note aims at describing the LwIP stack and how to use it to design a UART to Ethernet Gateway. This application note will elaborate the software architecture, internal data transmission scheme and memory footprint to help users make their own Gateway easily according to the real requirement.
The Atmel® SAM4S Xplained Pro evaluation kit is a hardware platform to evaluate the ATSAM4SD32C microcontroller. Supported by the Atmel Studio integrated development platform (IDE), the kit provides easy access to the features of the Atmel ATSAM4SD32C and explains how to integrate the device in a custom design. The Xplained Pro MCU series evaluation kits include an on-board Embedded Debugger, and no external tools are necessary to program or debug the ATSAM4SD32C. The Xplained Pro extension series evaluation kits offer additional peripherals to extend the features of the board and ease the development of custom designs.
