I have an example of the cdc class implementation from texas but it was done on the IAR environment and I am having difficulty in porting it to the KEIL environment. Does someone maybe have an example of the usb cdc implementation on this micro for the KEIL environment. Or otherwise is there a general example of the cdc class implementation for the 8051 somewhere?
In general, 8051's rely upon specific hardware to do the bulk of USB - so there isn't any such thing as a "general 8051" implementation and, therefore, there can't be any general examples for it!
