Macro Definition Documentation

◆ FIFO_WMRK_SIZE

#define FIFO_WMRK_SIZE (8) /* Buffer 8 Samples. */

Definition at line 61 of file mpl3115_fifo.c.

Referenced by main().

◆ MPL3115_DATA_SIZE

#define MPL3115_DATA_SIZE (5) /* 3 byte Pressure/Altitude and 2 byte Temperature. */

Definition at line 62 of file mpl3115_fifo.c.

Referenced by main().

◆ MPL3115_SAMPLING_EXPONENT

#define MPL3115_SAMPLING_EXPONENT (0) /* 1 second. */

In MPL3115 the Auto Acquisition Time Step (ODR) can be set only in powers of 2 (i.e. 2^x, where x is the SAMPLING_EXPONENT). This gives a range of 1 second to 2^15 seconds (9 hours).

Function Documentation

◆ main()

int main ( void )

Main function.

Set the I2C Power mode.

Set the I2C bus speed.

Initialize MPL3115 sensor driver.

Set the task to be executed while waiting for I2C transactions to complete.

Configure the MPL3115 sensor.

Wait for data ready from the MPL3115.

Read new raw sensor data from the MPL3115.

Process all samples and convert the raw sensor data.
