pamoja-field-io
The wires a gateway actually has: framed serial packets, an RS485 request and the reply it draws, a CAN frame, the address a chip answers on, and the bus that carries a driver to the part.
One install for the 5 capabilities of this domain. Each is also its own
distribution, and pamoja is the whole framework in one.
pip install pamoja-field-io
from pamoja.field_io import serial
| Capability | Module | What it covers |
|---|---|---|
| Serial framing | pamoja.serial |
SLIP and COBS byte stuffing with streaming decoders, so a UART byte stream carries discrete packets |
| Modbus RTU | pamoja.modbus |
Modbus RTU for RS485 field devices: a client that polls them over a serial port with the line's timing, simulated devices that answer as real ones do, and the frames with their CRC-16/MODBUS |
| CAN and J1939 | pamoja.can |
CAN 2.0 and CAN FD frames with 11- and 29-bit identifiers, J1939 decode and compose, and a node on a bus, simulated or a Linux interface through SocketCAN |
| I2C, SPI, and GPIO | pamoja.gpio |
I2C address frames with reserved-range checks, the four SPI clock modes, active-high or active-low switches and contacts, and GPIO lines opened on a Linux board |
| Buses | pamoja.hal |
The embedded-hal traits every driver takes, a bit-banged 1-Wire bus, simulated parts and scripted buses that stand in for hardware, the Linux backends over i2c-dev, spidev, and the GPIO character device, one I2C bus and one serial port a program and its drivers share, and delays that sleep or only count |
The guides, with a worked Python example for each, are at https://pamoja.molex.cloud/docs.
