Module configuration options

Configure Options

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

Define Options

name: BMP3_SLAVE_ADDR value: BMP3_I2C_ADDR|BMP3_I2C_ADDR_ALT
Description: i2c slave address (default BMP3_I2C_ADDR)
name: BMP3_SYNC_SEND value: None
Description: flag to transmit the data as it is acquired
name: BMP3_COMPENSATION value: BMP3_SINGLE_PRECISION_COMPENSATION
Description: select precision for compensation (single precision, double precision, or integer)

Module functions

Init Functions

These initialization functions are called once on startup.

baro_bmp3_init()

Event Functions

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

baro_bmp3_event()

Periodic Functions

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

baro_bmp3_periodic()
- Frequency in Hz: 50
- Autorun: LOCK
  Periodic function automatically starts after init and can't be stopped.
