minimal-TCP/IP stack is a portable network stack API using the enc28j60 ethernet module on ARM-cortex M4 architecture based board for non OS enviornment. Tested on (Texas Instruments TM4c123gh series processor), developed as a part of course projects (EE6314) at the University of Texas at Arlington. This API was used to provide a network layer interface for the home automation project and MQTT gateway project for low power sensor network.

• Simple and easy to use API.
• Implements Ethernet layer, ARP, ICMP, TCP and UDP protocols.
• Supports Dynamic IP through DHCP.
• API based layers for raw TCP and UDP sockets.
• Supports max MTU of 1500 bytes.
• Lightweight stack usage of approximate 4096 bytes for medium scale MCU based embedded systems.
• Portable, can be ported to other platforms.
• Extensively tested as TCP and UDP clients and also as clients with application layer protocols like MQTT.

• Linux Sockets like API.
• Support for multiple sockets.
• RTOS based testing and support.

The API is tested on TIVA Launcpad by Texas Instruments and enc28j60 module.

ENC28J60 Ethernet controller connected on the following pins :-

• MOSI (SSI2Tx) on PB7
  
• MISO (SSI2Rx) on PB6
  
• SCLK (SSI2Clk) on PB4
  
• ~CS (GPIO) on PB1
  

Test code is dependent on the following APIs:-

• Clone "clterm" Repo from : https://github.com/adimalla/clTerm
• Clone "MQTT-3.1-C" Repo from : https://github.com/adimalla/MQTT-3.1-C
