INA260 Power Sensor Driver

Product page Datasheet Address: 0x40 (A0=A1=GND) Drivers available: INA226 mfid @ 0xFE = 0x5449

NuttX app needs to be created to interface with the sensor through the driver. INA226 example app: apps/examples/ina226/ina226_main.c INA226 board level initialization example: boards/arm/stm32l4/nucleo-l432kc/src/stm32_ina226.c

Differences from INA226:

• specs
• register map
• different registers (INA260 does not have REG_SHUNT_VOLTAGE, REG_CALIBRATION. Instead, INA260 can measure current across shunt resistor without conversion.)
• Different field in configuration register bits 3-5 (CONFIG_ISHCT instead of CONFIG_VSHCT due to the point above)

The app now outputs measurements from the sensor. The number of samples that are collected and averaged can be configured. Need to make it configurable Both bus voltage conversion time and shunt current conversion time can be configured. Need to make it configurable
