Code to test wiznet WIZ810MJ module
|
||||
|
||||
See:
|
||||
|
||||
<http://code.rancidbacon.com/LearningAboutArduinoWIZ810MJ>
|
||||
|
||||
Current features:
|
||||
|
||||
* Read register/address values
|
||||
|
||||
* Write register/address values
|
||||
|
||||
* Configure networking to enable ping (old style)
|
||||
|
||||
* Initial W5100 driver port:
|
||||
|
||||
+ new-style network configuration
|
||||
|
||||
+ socket creation/listening/closing
|
||||
|
||||
+ Sending/Receiving okay
|
||||
|
||||
+ example "echo" server
|
||||
|
||||
* Terrible hacked-together code
