workflow:
|
|
|
|
- connect zprobe (note: it currently inverts because it didn't have any
|
|
other chips around. this may change later.)
|
|
|
|
- capture the USB signals at an interesting moment with a sample rate of
|
|
50 MSa/s
|
|
|
|
- zoom into the frame(s) of interest
|
|
|
|
- download the data with
|
|
./get.py
|
|
|
|
- decode with
|
|
./dec.py
|
|
|
|
For manual decoding, set the coders to D+ and D- (we need D- for SE0
|
|
and SE1 detection), then click on a rising clock edge left of the
|
|
packet and move the cursor to the right.
|
|
|
|
- if there are problems with the clock, the analog signal and digital
|
|
signals derived from it can be examined after running dec.py with
|
|
./plot
|
|
|
|
(Note that the digital zprobe hides any analog anomalies.)
