Module configuration options

Configure Options

name: BMP280_USE_SPI value: None
Description: select which bus type use (default I2C -> FALSE, SPI -> TRUE)
name: BMP280_DEV value: i2cX/spiX
Description: select which i2c/spi peripheral to use (default i2c1/spi1)
name: BMP280_SLAVE_IDX value: spi_slave0
Description: select which slave peripheral to use when bus is spi (default spi_slave0)

Define Options

name: BMP280_SLAVE_ADDR value: BMP280_I2C_ADDR|BMP280_I2C_ADDR_ALT
Description: i2c slave address (default BMP280_I2C_ADDR)
name: BMP280_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.

baro_bmp280_init()

Event Functions

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

baro_bmp280_event()

Periodic Functions

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

baro_bmp280_periodic()
- Frequency in Hz: 50
- Autorun: LOCK
  Periodic function automatically starts after init and can't be stopped.
