/* Notes by Ben Lunt:
|
|
|
|
- My purpose of coding this emulation was/is to learn about the USB.
|
|
|
|
It has been a challenge, but I have learned a lot.
|
|
|
|
- 31 July 2006:
|
|
|
|
I now have a Beagle USB Protocol Analyzer from Total Phase for my research.
|
2014-09-22 23:49:39 +04:00
|
|
|
(http://www.totalphase.com/products/beagle-usb12/)
|
2012-09-02 13:37:47 +04:00
|
|
|
With this device, I plan on doing a lot of research and development to get this
|
|
|
|
code to a state where it is actually very useful. I plan on adding support
|
|
|
|
of many "plug-in" type modules so that you can simply add a plug-in for your
|
|
|
|
specific device without having to modify the root code.
|
|
|
|
I hope to have some working code to upload to the CVS as soon as possible.
|
|
|
|
Thanks to Total Phase for their help in my research and the development of
|
|
|
|
this project.
