Sample code required for understanding USB (Control and Bulk mode) on STM32F4Discovery

[robomon 0]

Hello All,

 

Currently I am learning about USB protocol. I need to implement some real examples on my STM32F4Discovery board. The only example I can find is the virtual serial port using USB.

 

I want to understand how to use the control, interrupt, bulk and isochronous data transfer types. But I can't find implementation examples for this.

 

Could anyone of you point me some links to some USB implemantations ? I also need to know the host side implementations on libusb. If any code for that also would be a great help.

 

The example which I am searching for is an USB to ADC interface which can transfer ADC samples at very fast rate to computer so that I can get a good quality signal view.

 

Thanks,

Jayfree
