Development steps:

  • initial integration with mbed RTOS
  • generic mbed Ethernet driver
  • high performance NXP LPC1768 specific Ethernet driver
  • Multi-threading support for mbed RTOS
  • Berkeley sockets and integration with the New Socket API
  • Fork of the apps running on top of the New Socket API
  • Scheduling optimizations
  • Debugging/benchmarking/testing

Demo application (measuring TCP sender performance):

Import programlpc1768-picotcp-demo

A PicoTCP demo app testing the ethernet throughput on the lpc1768 mbed board.
