pamoja-field-io
The wires a gateway actually has: framed serial packets, an RS485 request and the reply it draws, a CAN frame, and the address a chip answers on.
One install for the 4 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 requests and replies with CRC-16/MODBUS for RS485 field devices |
| CAN and J1939 | pamoja.can |
CAN 2.0 and CAN-FD frames with 11- and 29-bit identifiers, plus J1939 decode and compose |
| I2C, SPI, and GPIO | pamoja.gpio |
I2C address frames with reserved-range checks, the four SPI clock modes, and active-high or active-low pins |
