Firmware

In order to use this device, the sigrok-firmware-fx2lafw (>= 0.1.4) firmware is required.

The firmware was originally written by Jochen Hoenicke (see README for details), thanks a lot!

Note: The firmware is not flashed into the device permanently! You only need to make it available in the usual place where libsigrok looks for firmware files, it will be used automatically (and "uploaded" to the Cypress FX2's SRAM every time you attach the device to a USB port).

Note: On Windows, you will have to assign the WinUSB driver via Zadig twice: the first time for the initial USB VID/PID the device has when attaching it via USB (04b4:6022 or 04b5:6022, depending on which vendor driver is currently being used by the device), and a second time after the firmware has been uploaded to the device and the device has "renumerated" with a different VID/PID pair (1d50:608e).

Example sigrok-cli commands

Example sigrok-cli commands for the Hantek 6022BE. See sigrok-cli for a full list of available commands.

Display the capabilities of the device attached

  sigrok-cli --driver hantek-6xxx --show

To show the options of the channel group "CH1"

  sigrok-cli --driver hantek-6xxx --channel-group CH1 --show

Example for collecting 100 samples at 1MHz

  sigrok-cli --driver hantek-6xxx --config samplerate=1m --samples 100

For collecting samples for 100 ms

  sigrok-cli --driver hantek-6xxx --time 100

For collecting 20k samples at 1MHz sample rate and save to a csv file in the sigrok-cli directory. May require admin rights depending on sigrok-cli install location.

  sigrok-cli --driver hantek-6xxx --config samplerate=1m --output-file test.csv --output-format csv --samples 20k

Note: sigrok-cli can only be used with one Hantek 6022BE device at a time.
