Learning Sigrok
Yutaka Niibe at
I develop my USB driver with no USB alalyzer or digital alalyzer. I mean, with no looking any signals on wire.
Last week, I looked the signal using Sigrok. With my ZEROPLUS, only it can caputure three frames of USB (3ms). But I can see the transactions: command from host, response from device, seven NAKs while responding an answer.
