This is a P8X32A/Propeller 1, P2X8C4M64P/Propeller 2 driver object for the TI INA260 Precision Current and Power monitor IC
IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.
- I2C connection at up to 400kHz, with alternate address support
- Read manufacturer ID, die ID
- Read shunt current, bus voltage, calculated power
- Set operation mode (one-shot/triggered, continuous, power-down)
- Set conversion time for voltage and current measurements
- Set measurement averaging samples
- Set interrupt/alert source, threshold, active state (open-collector high/low), latching
- Read flags: conversion ready, power overflowed
P1/SPIN1:
- spin-standard-library
- P1/SPIN1: 1 extra core/cog for the PASM I2C engine (none if the bytecode-based engine is used)
- sensor.power.common.spinh (provided by spin-standard-library)
P2/SPIN2:
- p2-spin-standard-library
- sensor.power.common.spin2h (provided by p2-spin-standard-library)
| Processor | Language | Compiler | Backend | Status |
|---|---|---|---|---|
| P1 | SPIN1 | FlexSpin (6.9.4) | Bytecode | OK |
| P1 | SPIN1 | FlexSpin (6.9.4) | Native/PASM | OK |
| P2 | SPIN2 | FlexSpin (6.9.4) | NuCode | OK |
| P2 | SPIN2 | FlexSpin (6.9.4) | Native/PASM2 | OK |
(other versions or toolchains not listed are not supported, and may or may not work)
- Interrupt threshold parameter is currently a word, which isn't very intuitive
- Doesn't support high-speed mode (2.94MHz)
