The Copperduino board is based on the Arduino Uno form fit and is compliant with a plethora of Arduino shields.
Communication with other CopperLan hardware and applications can be done via its Ethernet or USB connectors.
In both cases, the needed divers are all included and ready to use. On computers, these are part of the CopperLan package so that you can concentrate exclusively on your application.
There is no need to modify your application to re-target it from USB to Ethernet or vice versa.
The Copperduino board is powered by two powerful processors, one solely dedicated to your application and the other one offering the whole set of CopperLan services as a turnkey solution.
They communicate together via a super-fast duplex serial line (20Mbit/sec each way); this link is called CHAILink
The CHAILink is a way of controlling the CopperLan Host Application Interface (CHAI) through Remote Procedure Call (RPC).
On the Copperduino, the CopperLan service resides in the Ethernet MCU, while the client MCU contains your application code compiled together with the CHAILink-related client code (provided as C source).
Using CopperLan via CHAILink offers to embedded the same functionality as to applications running in a MAC or PC.
The CHAILink SDK is documented here.
Programming is done via a Microchip® ICSP compliant 6-pin header.
Compatible debugging/programming tools include Microchip's low-cost Pickit3® and MPLAB® software
