This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the INA1x9-series analog DC current sensors.

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.

• Object-oriented: attach any compatible ADC driver from the top-level application
• Set circuit parameters: Rs (shunt) and Rl (load) resistance values
• Set optional sample averaging
• Set optional current bias/offset

P1/SPIN1:

• spin-standard-library
• sensor.power.common.spinh (provided by the spin-standard-library)
• an ADC driver to measure the shunt voltage (e.g., MCP320x)

P2/SPIN2:

• p2-spin-standard-library
• sensor.power.common.spin2h (provided by the p2-spin-standard-library)
• an ADC driver to measure the shunt voltage (e.g., MCP320x)

(other versions or toolchains not listed are not supported, and may or may not work)

• Tested with Adafruit PID# 1164 (INA169), connected via an MCP3202 ADC

• Very early in development - may malfunction, or outright fail to build
• Voltage and wattage functions return 0 since the sensor only has current measurement capability
