Module configuration options

Configure Options

name: MS5611_SPI_DEV value: spiX
Description: select spi peripheral to use (default spi1)
name: MS5611_SLAVE_IDX value: SPI_SLAVE0
Description: SPI slave select index

Define Options

name: SENSOR_SYNC_SEND value: None
Description: flag to enable sending BARO_MS5611 message on every new measurement

Module functions

Init Functions

These initialization functions are called once on startup.

baro_ms5611_init()

Event Functions

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

baro_ms5611_event()

Periodic Functions

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

baro_ms5611_read()
- Frequency in Hz: 4
- Autorun: LOCK
  Periodic function automatically starts after init and can't be stopped.
baro_ms5611_periodic_check()
- Frequency in Hz: 40
- Autorun: LOCK
  Periodic function automatically starts after init and can't be stopped.
