Course D106
TCP/IP Programming in 'C' using the Microchip TCP/IP Protocol Stack

Duration: 5 Days

Intended Audience

This course is for engineers who have a good knowledge of C programming and also a sound appreciation of TCP/IP networking. It is aimed specifically at developers who will be implementing socket based, embedded web server based and embedded SNMP based applications on embedded targets

Course Overview

'C' programming of TCP/IP applications requires a good understanding of the TCP/IP protocol and how to use the API functions supplied with Protocol Stack implementation. Where the Protocol Stack has been optimized for use in embedded systems configuration and building of the protocol stack to include just those features that need to be included in a given application need also to be taken into account.

Key Skills

After attending this cours you will be able to:

• Understand the Microchip TCP/IP Application Programming Interface functions and how to use them on PIC18, PIC24, dsPIC and PIC32 systems with external Ethernet PHY/MAC devices and on-chip PHY/MAC devices, both 10 and 10/100 Mbps devices
• Understand how to use the Microchip TCP/IP stack both stand-alone and together with the Free RTOS real time operating system
• Implement embedded web server oriented applications on dsPIC target platforms
• Be able to design web pages that contain form based functionality as well as Java applets that can be used as a means by which the embedded web server can continually push information down onto the web page
• Understand how URIs are interpreted and make use of Ajax techniques to implement responsive web based appliatins
• Implement code for generating web pages dynamically
• Implement an SNMP agent on an embedded target system

Course Contents

Overview of TCP/IP

• IP addressing and subnet masking - and how they are represented in the Protocol Stack
• IP, TCP and UDP headers and their underlying data structures
• The TCP and UDP protocols

TCP/IP - client-server implementation strategies

• Principles of sockets API based programming
• Implementing higher layer protocols in TCP/IP
• case studies exploring implementation of:
  • DHCP
  • TFTP
  • FTP
  • HTTP
  • SNMP

Installing and configuring the Microchip TCP/IP Protocol stack on standalone (without an OS) systems - and interfacing to the underlying hardware (ethernet and serial controllers)

Integrating the Microchip TCP/IP stack into a FreeRTOS based application

Implementing SCADA type applications on top of UDP

An introduction to implementing SNMP agents on embedded targets so that these targets can be managed via an SNMP management station

Designing GUI-based control applications running on Windows or Linux workstations to control TCP/IP enabled embedded systems (the GUIs will Qt based for portability). This part of the course can be tailored to use Microsoft Forms or Microsoft WPF if required.
