1.15 TCP/IP WEB NET Server Super Set Application
This application demo enables almost all the Application Layer modules in MPLAB® Harmony 3 TCP/IP Stack. It is also based on Web Net Server SD Card application.
Description
The TCP/IP WEB NET Server Super Set application is based on MPLAB® Harmony 3 TCP/IP Stack.
The Harmony TCP/IP stack is a collection of different network protocols.
The source files of Harmony 3 TCP/IP stack is available here.
The demo is created with MPLAB X IDE and MCC plugin.
MCC Project Graph - TCP/IP WEB NET Server Super Set
The following Project Graph shows the Harmony components included in the TCP/IP WEB NET Server SD Card demo application.
FreeRTOS component is required for RTOS application. For bare-metal (non-RTOS) FreeRTOS component should not be selected.
wolfSSL component is added for secure connection which supports TLS.
wolfCrypt module enabled with MD5 and SHA authentication
FILE SYSTEM is added to read and write from the SDMMC( sdcard ) module with FAT file system.
TCP/IP Configuration - TCP/IP WEB NET Server Super Set
The TCP/IP modules enabled for the demo is shown in the TCP/IP Configuration Overview
More details of TCP/IP Configuration plugin is available here
The Ethernet interface in this demo-configuration use GMAC peripheral and Gigabit Ethernet PHY Transceiver KSZ9131.
The Ethernet interface in this demo-configuration use GMAC peripheral and Gigabit Ethernet PHY Transceiver LAN8840.
The Application Layer modules enabled in the demo are as follows:
- Application Layer
Modules
- ANNOUNCE to discover the Microchip devices within a local network.
- Berkeley API provides the Berkeley_Socket_Distribution (BSD) wrapper to the native Harmony TCP/IP Stack APIs.
- DHCP Client to discover the IPv4 address from the nearest DHCP Server.
- DHCP SERVER is used to assign IP addresses to DHCP clients from the configured IP address database.
- DHCPv6 CLIENT module will allow your application to dynamically obtain an IPv6 address from a DHCPv6 server.
- DNS Client provides DNS resolution capabilities to the stack. DNS CLIENT also known as the DNS Resolver, will try to resolve the IP address from its local resources, which includes the Name to Address mappings in the local DNS cache.
- DNS SERVER translate domain names into IP addresses.
- FTP CLIENT module allows application to upload the files to, and download the files from, any FTP server.
- FTP SERVER facilitates the uploading of files to, and downloading of files from, a network device.
- HTTPNET SERVER enables the target board to act as a Web Server for the secured port number 443.
- IPERF implements the iPerf protocol to measure networking bandwidth and performance
- NBNS NetBIOS Name Service protocol associates host names with IP addresses. This assign of human-name host names to access boards on the same subnet.
- SMTP CLIENT let applications send e-mails to any recipient worldwide.
- SNTP Simple Network Time Protocol updates its internal time periodically using a pool of public global time servers.
- TELNET provides bidirectional, interactive communication between two nodes on the Internet or on a Local Area Network.
- TFTP CLIENT module supports reading and writing of files (or mail) from/to a remote server.
- TFTP SERVER is a simple protocol used to transfer files. It waits for client requests to read and write files.
- ZEROCONF enables devices on an IP network to automatically configure themselves.

Hardware Setup - SAM9X75-DDR3-EB
The target board for running the application is SAM9X75-DDR3-EB.
This section provides essential hardware configuration of this target board to run TCP/IP applications.
Board Setup
- Default jumper setting of the board is a shown above.
- Connect USB cable between USB-A port (J28) and host PC. This will supply 5V power to board.
- Connect serial cable (FTDI) for debug console output on DBGU1(J36) port.
- Connect Ethernet cable between RJ45 socket (J18) and router/switch/computer.
Hardware Setup - SAM9X75-Curiosity
The target board for running the application is SAM9X75-CURIOSITY.
This section provides essential hardware configuration of this target board to run TCP/IP applications.
Board Setup
- Default jumper setting of the board is a shown above.
- Connect the Micro-USB cable between USB-A port on the board and host PC. This will supply power to the board.
- Connect a USB-UART converter for console output between the UART DEBUG port on the board and host PC.
- Connect the debugger/programmer between JTAG connector on the board and host PC.
- Insert an SD-Card into the μSD-Card connector as shown above .
- Connect Ethernet cable between RJ45 connector and router/switch/computer.
Setting up at91bootstrap loader
To load the application binary onto the target device, we need to use at91bootstrap loader.
Refer to the at91bootstrap loader documentation for details on how to configure and run/debug the application using MPLABX and booting application using an SD Card.
Running the Application
- Open a terminal application on the host computer (like Hyper-terminal or Tera Term).
- Configure the terminal application for serial port connected to UART DEBUG port.
- Set baud rate as 115200 in the terminal application.
- Build and download the application project on the target board.
- Ensure connection from Gigabit(1000Mbps) capable network socket of a router/switch/computer to the board.
- Ensure SD card is formatted and loaded with the web pages provided within the /net_apps_sam_9x7/apps/web_net_super_set_sdcard_fatfs/firmware/src/web_pages directory.
- Insert SD Card to its slot on target board.
- Verify the TCP/IP Stack initialization console messages.
If DHCP client is enabled in the demonstration, wait for the DHCP server to assign an IP address for the development board.
This will be printed on the console. Otherwise, the default static IP address will be assigned to the board.
Demo Test
- To test the web server functionality, refer Web Net Server demo.
- The command interface is enabled for all the Application Layer modules. These modules can be configured and tested with commands from Console.
