example_linux_scopevis fails with "data length differ"

[moritzschaefer]

Running the example there are always only around 400-800 sample points.

!@! ~/tmp/Hantek6022API (master) $ python2 examples/example_linux_scopevis.py
data lengths differ!
[('timing', 8192), ('voltage', 609)]
!@! ~/tmp/Hantek6022API (master) $ python2 examples/example_linux_scopevis.py

I had the same problem, I originally thought it was because I was running on arm64.

I found something interesting, after changing the sample_rate_index in example_linux_scopevis.py to a minimum of 0x10 (100kHz) the second time I run it, it has a high chance of success!

Then change it to 0x01 (1MHz) and it will work the first time, but obviously this method is very inconvenient, maybe modifying the firmware can solve it ...... I'm still trying to solve the problem.

This is the screen of my successful execution
