Features Supported

  • API to configure INA sensor using I2C interface
  • Provides API to return current values from the INA

SysConfig Features

Note
It is strongly recommend to use SysConfig where it is available instead of using direct SW API calls. This will help simplify the SW application and also catch common mistakes early in the development cycle.
  • Option to configure INA registers
  • Supported INA devices
    • INA228
