scirodev

Host-side companion to the PeakHub firmware: typed API stubs for the sciro namespace that PeakHub programs import, plus the hub tooling (it depends on pybricksdev, so scirodev run ble prog.py works exactly like pybricksdev).

pip install scirodev                                    # from PyPI
pip install "scirodev @ git+https://github.com/sciurus-robotics/scirodev.git@v0.1.0"
pipx install scirodev                                   # just the CLI, in its own venv

Hacking on it:

pip install -e .

Then your IDE/type checker knows these, which the upstream pybricks stubs don't:

from sciro.parameters import Port          # Port.A .. Port.H (PeakHub has 8 ports)
from sciro.iodevices import PUMPDevice     # generic PUMP device access
from sciro.pump import FloorPro        # PUMP devices (LP-FloorPro, ...)
from sciro.hubs import PeakHub             # hub class incl. display.device()
from sciro.tools import RingBuffer         # experimental: RAM recorder -> CSV file via the console
from sciro.robotics import PIDController   # experimental: PID with optional logging

hub = PeakHub()
fp = FloorPro(Port.G)
cog_dark, cog_bright, brightness, darkness, mask, calibrating = fp.line.read()
hub.display.device(fp, brightness=50)      # mirror the sensor's LED strip on the 5x5

Experimental (API may change): a RAM recorder that publishes CSV through the console, and a PID controller that can log into it:

from sciro.robotics import PIDController
from sciro.tools import RingBuffer

pid = PIDController(kp=15, kd=0.2, output_limit=300)
log = pid.make_log(seconds=10, rate=100)     # RingBuffer of pid.LOG_FIELDS
turn_rate = pid.update(error, derivative=-hub.imu.angular_velocity(Axis.Z))
log.publish("doc/pid_run.csv")               # scirodev run writes the file next to the script

The drivebase's own controllers log too (built into Pybricks, undocumented upstream): db.heading_control.log.start(5000, down_sample=2) records the reference trajectory, the estimated state and the P/I/D terms at 100 Hz from the firmware's control loop; db.heading_control.log.publish("heading.csv") writes it with a header line. sciro.robotics.DriveBase is the Pybricks class with these attributes typed. log.record(db.state) is the coroutine form for anything else.

publish(path) wraps the CSV in pybricksdev's _file_begin_ <path> / _file_end_ lines; scirodev run (and pybricksdev run) then write the block to that file, relative to the script's folder, instead of echoing it. Without a path the CSV goes to the terminal.

Full demo programs for the LP FloorPro (both for LEGO hubs and the PeakHub) live in sciurus-robotics/FloorPro-CodeDemos; examples/ here stays minimal.

On the hub these modules are frozen into the PeakHub firmware: sciro.parameters and sciro.iodevices re-export the same runtime objects as their pybricks.* counterparts, so sciro.parameters.Port is pybricks.parameters.Port — the stubs only add what the IDE is missing. The stub files here mirror the frozen modules; a release of this package matches the PeakHub firmware of the same date.

Releasing

Bump version in pyproject.toml, commit, tag vX.Y.Z and push the tag. The GitHub workflow builds, type-checks and publishes to PyPI via Trusted Publishing (configured on pypi.org: owner sciurus-robotics, repo scirodev, workflow publish.yml, environment pypi).
