The DreamSourceLab DSLogic is a 16-channel USB-based logic analyzer, with sampling rates up to 400MHz (when using only 4 channels).

See DreamSourceLab DSLogic/Info for more details (such as lsusb -v output) about the device.

Firmware

In order to use this device with libsigrok the vendor firmare and bitstream files (v0.97) are required.

The easiest method to install those is to use the sigrok-fwextract-dreamsourcelab-dslogic script. It will download the correct files, rename them to the correct filenames as expected by libsigrok and install them.

Example usage:

$ PREFIX=$HOME/sr ./sigrok-fwextract-dreamsourcelab-dslogic

This will install the files into $HOME/sr/share/sigrok-fimware. Without PREFIX, the files will be installed into /usr/local/share/sigrok-firmware by default.

If you want to avoid using the script, you can manually download and rename the files (but check the script for the correct filenames).

Note: Do not use any firmware/bitstream files newer than those linked here (v0.97), they're currently not supported. See bugs #905 and #1063.

After firmware is correctly installed, you can see if it's worked like this:

sigrok-cli --driver=dreamsourcelab-dslogic -l 5 --scan

You should see the driver detected and uploading the firmware

Capabilities

Use --show to fetch the current available options

sigrok-cli --driver=dreamsourcelab-dslogic --show

This example shows how to use sigrok-cli to capture 1k samples at 500khz on channels 0 and 1, with voltage threshold of 2.5v

sigrok-cli -C 0,1 --driver=dreamsourcelab-dslogic  -c "samplerate=500k:voltage_threshold=2.5-2.5" --samples 1k

This example shows continuous capture (requires the device config to include 'continuous=on')

sigrok-cli -c "samplerate=10k:voltage_threshold=2.5-2.5:continuous=on" --driver=dreamsourcelab-dslogic --continuous
