Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

1 <module name="baro_bmp3">
2  <define name="BMP3_SLAVE_ADDR" value="BMP3_I2C_ADDR|BMP3_I2C_ADDR_ALT" />
3  <define name="BMP3_SYNC_SEND" />
5  <configure name="BMP3_I2C_DEV" value="i2cX" />
6 </module>

Module configuration options

Configure Options

  • name: BMP3_I2C_DEV value: i2cX
    Description: select which i2c peripheral to use (default i2c1)

Define Options

    Description: i2c slave address (default BMP3_I2C_ADDR)
  • name: BMP3_SYNC_SEND value: None
    Description: flag to transmit the data as it is acquired
    Description: select precision for compensation (single precision, double precision, or integer)

Module functions

Init Functions

These initialization functions are called once on startup.

Event Functions

These event functions are called in each cycle of the module event loop.

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.
