USB Explorer 200 - Feature Tour
Grouping consecutive SOFs and NAKs
Consecutive Start Of Frames are grouped to prevent an overload of the display |
This example shows the end of the enumeration of an HID peripheral and the start of an interrupt flow on endpoint 1 at an interval of 10 milliseconds (rounded down to 8 milliseconds by the operating system) |
Like SOFs, consecutive NAK transactions of the same type are grouped |
This illustration shows the writing of a file to a mass storage peripheral. We can see how each completed transaction is preceded by one or more NAKs wasting the bandwidth. |
