pamoja

Reference

Python reference#

Every pamoja module, generated by pdoc from this commit. Each row below opens a module's API pages, and the same capability in the other three languages is one step away.

Each capability is its own distribution and one module of the pamoja namespace, so an import names the capability it uses, and the page for each module lists its classes and functions with their signatures. pamoja installs all of them.

Each module is hand-written Python over pamoja-native, the compiled engine, whose type stub ships as pamoja/_native/__init__.pyi so an editor sees every native signature; pamoja.raw re-exports that contract for anything the facades do not cover.

By domain#

Six of the chapters hold more than one capability, and each is a package of its own on PyPI, pamoja-<domain>, which brings its capabilities in and re-exports each under its own name:

Sensing and actuationpamoja.sensing

Sensor drivers, Actuator drivers

pip install pamoja-sensing
Radio and reachpamoja.radio

Every package#

One row per capability: the install line, the module and its reference, the guide with the worked example, and the same capability on the other three reference pages, one step away.

Engine#

Engine surfacepamoja.core

The transport every link shares (send, receive, subscribe, and a faulty wrapper for tests) and the runtime version

pip install pamoja-core

Identity#

Device identitypamoja.security

ed25519 device identity: sign a reading and verify it, so a gateway can prove it is authentic

Helperspamoja.kit

Plain-language helper math: smoothing, calibration, PID and thermostat control, trend and surge prediction, rolling windows, kinematics, and geo

pip install pamoja-kit

Field I/O#

Serial framingpamoja.serial

SLIP and COBS byte stuffing with streaming decoders, so a UART byte stream carries discrete packets

pip install pamoja-serial
Modbus RTUpamoja.modbus

Modbus RTU requests and replies with CRC-16/MODBUS for RS485 field devices

pip install pamoja-modbus
CAN and J1939pamoja.can

CAN 2.0 and CAN-FD frames with 11- and 29-bit identifiers, plus J1939 decode and compose

pip install pamoja-can
I2C, SPI, and GPIOpamoja.gpio

I2C address frames with reserved-range checks, the four SPI clock modes, and active-high or active-low pins

pip install pamoja-gpio

Sensing and actuation#

Sensor driverspamoja.sensors

Datasheet-anchored decoders for eleven parts: the BME280, BMP280, DS18B20, HDC1080, INA219, INA226, ADS1115, OPT3001, SCD4x, SHT3x, and TMP117

pip install pamoja-sensors
Actuator driverspamoja.actuators

PCA9685 PWM and servo pulses, and stepper coil sequencing

pip install pamoja-actuators

Radio and reach#

LoRa airtimepamoja.lora

Time-on-air, duty-cycle off-time, and the regional channel plans a LoRa node must keep to

pip install pamoja-lora
LoRaWANpamoja.lorawan

LoRaWAN 1.0.x MAC framing, AES-CMAC and AES encryption, and both halves of the OTAA join

pip install pamoja-lorawan
Mesh framespamoja.mesh

Addressed, hop-limited, CRC-checked frames and duplicate suppression that floods a packet exactly once

pip install pamoja-mesh
Routingpamoja.routing

Reverse-path routing that learns the cheapest route from overheard traffic

pip install pamoja-routing

Trust and operation#

Audit logpamoja.audit

A tamper-evident, hash-chained log; altering, reordering, or dropping a record breaks verification

pip install pamoja-audit
Secured sessionpamoja.session

X25519 key agreement, HKDF, and ChaCha20-Poly1305 with an anti-replay window, with no TLS stack

pip install pamoja-session
Signed updatespamoja.update

Signed firmware manifests, streaming image verification, and A/B slots that fall back on their own

pip install pamoja-update
Powerpamoja.power

Duty cycling and an energy-aware governor that stretches work as the battery drains

pip install pamoja-power
Telemetrypamoja.telemetry

Observability that ships only what is worth the bytes as link cost rises, while counting everything

pip install pamoja-telemetry

Transports and testing#

MQTTpamoja.mqtt

An MQTT client with the topic and wildcard rules, as the core transport

pip install pamoja-mqtt
CoAPpamoja.coap

A CoAP client over UDP with confirmable delivery and observe

pip install pamoja-coap
Loopbackpamoja.loopback

An in-process transport with topic matching and a fault injector, for testing with no broker

pip install pamoja-loopback
Store and forwardpamoja.sync

Offline-first queues: in memory, and a crash-safe on-disk queue that survives power loss

pip install pamoja-sync
Transport ladderpamoja.ladder

Cheapest reachable link first, buffering to a store when every link is down

pip install pamoja-ladder
Event buspamoja.bus

An in-memory typed publish and subscribe event bus

pip install pamoja-bus
Simulatorspamoja.sim

Noisy and replay sensors, a recording actuator, and a simulated robot that dead-reckons its pose

pip install pamoja-sim

Profiles and robotics#

Device profilespamoja.profile

Named, ready-to-run device profiles from plain data or a JSON manifest

pip install pamoja-profile
ROS 2 rulespamoja.ros2

pip install pamoja-ros2
Zenoh keyspamoja.zenoh

Zenoh key expressions: validity, canonical form, and wildcard matching

pip install pamoja-zenoh
