Expand description

Creates an OPT3001 driver on a bus. Nothing is sent until pamoja_opt3001_init or the first pamoja_opt3001_measure.

§Arguments

  • bus - the bus the part is on; the driver holds its own share.
  • address - one of the PAMOJA_OPT3001_I2C_ADDRESS_ constants, by where ADDR is tied.
  • settings - the integration time and the range.
  • out_sensor - receives the driver.

§Returns

PamojaStatus::Ok with the driver in out_sensor, or PamojaStatus::InvalidArgument for a null argument.

§Safety

bus must be a live handle or null, and out_sensor a writable pointer or null.
