DL16 CLI

Non-official Linux CLI and Python protocol implementation for the DL16 logic analyzer. It supports PWM, finite/streaming capture, trigger, export, analysis, and offline protocol decoding. It is evidence-backed only for DL16, not DL32 or other models.

Install

Requires Linux, Python 3.10+, and libusb:

python3 -m pip install '.[usb]'

For CAN/LIN/JTAG/1-Wire and other sigrok decoders:

sudo apt install sigrok-cli

If USB permissions fail, install udev/99-dl16.rules, reload udev rules, and reconnect the analyzer. Normal work needs no list/info preflight; normal initialization handshakes first and uses endpoint clear/reset only after failure.

Quick capture

dl16 pwm verify --pwm0 1kHz,25 --input0 0 --pwm1 2kHz,75 --input1 8
dl16 capture run --buffer --channels 7,15 --sample-rate 250000000 --set-time 1 \
  --trigger rising --trigger-channel 7 --trigger-position 50 --output-dir capture
dl16 capture measure --input-dir capture --channel 7

Successful control and file-producing commands are silent. Measurements print only requested values unless a detailed format is explicitly selected.

The CLI chooses --sample-index by default and protects existing capture files. Use a new output directory unless replacement is explicitly requested with --force.
