Hantek 6254BD USB communication Labview

Eddie

Hi,
as it has been mentioned here several times, the oscilloscope software contains errors, the SDK is not well documented, etc. I would like to write software in Labview that would increase the oscilloscope's capabilities, which would certainly be good for Hantek. In Labview, it's best to use an instrument driver that uses RAW USB communication. I watched Hantek use Control and Bulk endpoint to control the oscilloscope, can you share a description of each USB command? For example, for the 6022BL communication is clear, thanks to the OpenHantek API, it would be good to have this for other oscilloscopes. Thank you.

I made a few attempts, the principle of communication is clear, but you need to know the meaning of each setting item.. Thank you for support
