Run `lager update --box ` after you upgrade the CLI. * **`lager update` installs the PicoTech SDK on a box that has none.** A box with no PicoScope headers in `/opt/picoscope/include` gets PicoTech's apt repo and the seven `libps*` packages, as `lager install` installs them. The update then rebuilds the scope daemon with PicoScope support, so a PicoScope works when you plug it in. Pass `--skip-picoscope` to leave the SDK out. On a box installed before v0.55.0, the update asks for the sudo password once to add the repo. * **The box's `lager` container has a memory limit.** The limit is three quarters of the host's RAM, and the host keeps at least 1 GiB. Set `LAGER_CONTAINER_MEMORY_MB` on the box to change the limit, or set it to `0` to remove it. * **`lager arm set-acceleration` checks the values that the arm reports.** The command exits non-zero when the arm reports values other than the ones you set. `Dexarm.set_acceleration()` returns the values, and raises `SettingNotAppliedError` when they differ. Without `--retract`, the arm now keeps its current retract value. The command used to set it to 60. * **`lager arm disable-motor` asks for confirmation**, because the arm goes limp and drops. A script that runs the command must pass `--yes`. * **`stream start` on a Rigol MSO5000 with no capture card paired exits 1.** It used to print "Streaming started" and exit 0. Pair a card with `lager nets set-capture`. ## Features * **Custom drivers can use Python packages.** Name a hashed requirements file in `lager_driver.json`, and `lager drivers install` installs those wheels with the driver. The packages survive `lager update`, and each driver gets its own. A `wheels/` folder serves a box with no internet access. `lager drivers list` shows a Deps column, and `lager drivers reinstall-deps` rebuilds the packages after a Python upgrade. See [`lager drivers`](https://docs.lagerdata.com/source/reference/cli/drivers). * **`lager arm get-acceleration` and `Dexarm.get_acceleration()`** print the arm's print, travel and retract acceleration. `Dexarm.read_settings()` returns the arm's whole settings report, which includes its stored calibration. * **The box debug service has a `POST /debug/halt` route.** It stops an OpenOCD net's core where it is, without a pulse on nRESET, as `DebugNet.halt()` does in Python. HTTP clients such as the Rust crate can now halt a part that executes in place. A J-Link net gets a 400 response. ## Bug Fixes * **A box with the PicoTech SDK but no PicoScope no longer runs out of memory.** The scope daemon retried the PicoTech drivers every few seconds, and each failed open kept memory. The host typically ran out overnight, and some hosts dropped off the network. The daemon now asks the drivers only when a PicoScope is plugged in. * **A Rigol DP800 supply refuses a negative voltage or current set through the Python API.** `set_voltage()` and `set_current()` sent the negative setpoint to the instrument. They now raise `ValueError` before anything is sent, as `lager supply` already did. * **A net command with the net name left out runs on the default net.** `lager arm position --box X` failed with "No such command '--box'". The fix covers `arm`, `supply`, `battery`, `eload`, `solar`, `logic`, `energy`, `scope`, `usb` and `watt`. * **A Keithley 2281S saved as a battery net and a supply net no longer blocks the battery net.** A read of the supply net's state held the instrument for about 20 seconds in battery mode. It now returns at once, as `CH1/?/battery mode`. * **An actuate net refuses an unsafe Dexarm move, as `lager arm` does.** It raises `OutOfBoundsError` for a position outside the workspace, and `UnsupportedFirmwareError` on firmware older than V2.1.4. A long move no longer times out after 5 seconds. * **The Dexarm works on firmware V2.4.x.** `lager instruments` finds an arm with no saved net, and `move --timeout` now times out. The timeout now starts when the move is sent. * **An MCC USB-202 recovers after its USB port is cycled.** `lager adc`, `dac`, `gpi` and `gpo` failed with "No MCC DAQ devices found" until the hardware service restarted. The box now restarts the service itself. The first command after the cycle can still fail, and it now says to retry in a few seconds. * **`lager usb NET cycle` holds an Acroname or YKUSH hub for the whole cycle.** Another command can no longer switch the port while it is off. A cycle right after `enable` now gives the device up to 5 seconds to appear. * **`lager install` with no terminal stops with the right message when sudo needs a password.** The check now asks the box `sudo -n -v`, which passes only when no command needs a password. * **The Rigol MSO5000 live view stays clear and current.** * A scope with no HDMI picture is no longer left with its Measure menu open. The next `lager scope NET start` brings the live view back after you plug the cable in. * The trigger source no longer opens the Trigger menu over the live view. * The scope follows settings changed at its front panel within about two seconds. * A move of a stopped scope's time position no longer starts it. * `trigger uart`, `i2c` and `pulse` are refused before anything is sent. * `trigger edge --level` reports the level that the scope took. * **The scope page clears when a PicoScope is unplugged.** The plot drops the last trace, and the header reads `STOP` with the sample rate and point count blank. ## Installation To install this version: ```bash theme={null} pip install lager-cli==0.60.0 ``` To upgrade from a previous version: ```bash theme={null} pip install --upgrade lager-cli==0.60.0 ``` Then update your boxes: ```bash theme={null} lager update --box ``` ## Resources [View Release on PyPI](https://pypi.org/project/lager-cli/0.60.0/) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
