Code to test wiznet WIZ810MJ module
|
|
|
|
See:
|
|
|
|
<http://code.rancidbacon.com/LearningAboutArduinoWIZ810MJ>
|
|
|
|
Current features:
|
|
|
|
* Initial W5100 driver port:
|
|
|
|
+ new-style network configuration
|
|
|
|
+ socket creation/listening/closing
|
|
|
|
+ Sending/Receiving okay
|
|
|
|
+ example "echo" server (new version with classes and multiple connections)
|
|
|
|
+ example "web server" with LED flash. (not currently)
|
|
|
|
* (slighty less) Terrible hacked-together code
