Module configuration options

Configure Options

name: BMP_I2C_DEV value: i2cX
Description: select which i2c peripheral to use (default i2c0)

Define Options

name: SENSOR_SYNC_SEND value: None
Description: flag to transmit the data as it is acquired

Module functions

Init Functions

These initialization functions are called once on startup.

Periodic Functions

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

baro_bmp_periodic()
- Frequency in Hz: 15
- Autorun: LOCK
  Periodic function automatically starts after init and can't be stopped.
