This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the INA3221 triple-channel power sensor.
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
- Soft-reset
- Read bus voltage, shunt voltage, current, and power (per enabled channels), shunt voltage (summed), bus voltage (summed) in ADC words or human-readable values (x1000000 scale integers)
- Set shunt resistance
- Set conversion time (Vbus, Vshunt)
- Set sample averaging mode
- Set operating mode: continuous or single-shot measurements, power down; any combination of bus and shunt voltage measurements
- Set interrupt thresholds (current, bus voltage, shunt voltage sum)
