If you want to avoid using the script, you can manually download and rename the files (but check [http://sigrok.org/gitweb/?p=sigrok-util.git;a=blob;f=firmware/dreamsourcelab-dslogic/sigrok-fwextract-dreamsourcelab-dslogic the script] for the correct filenames).

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.

Installing firmware files via a bash script

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.

Installing firmware files manually

If you want to avoid using the script, you can manually download and rename the files as follows:

You have to place the files into the sigrok-firmware sub-directory of where-ever you installed sigrok-cli or PulseView.

Example run

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 

sr: [00:00.014417] resource: Opened '/usr/local/share/sigrok-firmware/dreamsourcelab-dslogic-basic-fx2.fw'.

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
