Hi,
I am using USB Steallaris lib for communnicating with PC.
The question is about the "Start of frame" interrupt.
From what I know the SOF is the Host's packet from here there is three scenarious:
- Device isn't connected -> there is no SOF -> there is no SOF interrupt and this the exact behavior of my device.
- Device connected -> there is SOF -> there is SOF interrupt and this the exact behavior of my device.
- Device disconnected after it was connected -> there no SOF -> there is no SOF interrupt, but I still have the SOF interrupt, is it correct? What I am missing?
Thanks
Dani
