AVR32 lwIP Collections

AVR32 is a microprocessor architecture designed by Atmel. AVR32's lwIP example contains HTTP, TFTP and SMTP services. 

lwIP (lightweight TCP/IP)  is a free TCP/IP stack for many embedded processors, it is originally written by Adam Dunkels at the CNA lab of the Swedish Institute of Computer Science.

The following are old notes taken during my experiments on the above platforms when lwIP and AVR32 was not fully documented

• lwIP Workshop: how to build a TCP echo server

  • Raw API programming
  • Netconn programming
  • Socket programming

• lwIP Workshop: how to write an UDP echo broadcaster

  • Raw API programming
  • Netconn programming
  • Socket programming

• lwIP : how to enable DHCP client to acquire an IP from a DHCP server

• lwIP : how to enable keepalive

• lwIP : how to enable Automatic Private Internet Protocol Addressing (APIPA) with a DHCP client

• Fixing a glitch in AVR32's lwIP that causes erratic behaviors in the unblocking option of lwip_recvfrom 

• How to upgrade to the latest lwIP

• AVR32 Synchronous Serial Controller (SSC) and Peripheral Direct Memory Access Controller (PDCA)'s strange behavior

• Using AVR's Synchronous Serial Controller (SSC) and Peripheral Direct Memory Access Controller (PDCA)
