All you need to know about CopperLan is accessible in the doxygen guide below or in the SDK.
If there's something you can't find or understand, try searching for it in the forum.


You wish to undertake a Copperlan development? What do you need to know? Developers

Training sessions

We can arrange to have you visiting us and have a training session in our offices. This will no doubt accelerate the integration of CopperLan in your products

Computer and computer-like

To write such applications you need reading the CopperLan Host Application Interface (CHAI).
Coding is object oriented in C++.
The CHAI part of the SDK allows you writing multi-platform code. This also allows validating an application on a computer before porting it to a hardware

The development tools required for the various platforms are:

  • For Windows: Visual studio from VS2008
  • For Mac/iOS: XCode from V4
  • For embedded Linux: depends on the platform


There are various physical implementations but they all rely on only two coding models:

1. Object-oriented in C++, using the CHAI, with two variations:

  • Embedded Linux: see Computer model hereabove
  • Microcontroller under FreeRTOS, using Keil’s MDK Cortex-M tools
2. Through Remote Process Control (RPC) in C language and using the CHAILink.

For these implementations, you need reading both the CHAI and CHAILink documentations.
We provide you with client source code in C.
Any IDE and C-compiler can be used to write your application (firmware).

Reference designs

Using your own processor

  • For USB implementations you can use any MCU you want, the only additional job compared to using the STM32L100 is the coding of the USB transport, using our source code as a reference.
  • For Ethernet hardware based on Linux, we can provide a precompiled CopperLan implementation after getting all the details of your Linux setup and toolchain if necessary.
  • For Ethernet hardware running some other OS than Linux, we need:
    • our own copy of your entire dev system (HW + SW tools) - no need for your app code!
    • a running version of your platform
    • access to the Ethernet stack to handle the CopperLan frames
    • access to OS primitives:
      • Threads
      • Mutex/Events (Semaphore)
