|
* @brief BACnet/IP for Wiznet on Arduino-Uno
|
|
*
|
|
* This port is for BACnet/ip and uses part of the Arduino Ethernet
|
|
* library so it needs the stock Arduino Etherenet Shield
|
|
* (the one with the W5100 chip). The port was done by writting a C
|
|
* wrapper around the c++ Ethernet library and adapting the
|
|
* existing port for Atmega168 (mainly functions bip.c and bip-init.c)
|
|
* to use the wrapper functions. The port also needs Arduino core and
|
|
* Ethernet libraries to compile.
