Function Documentation

main()

int main

(

void

)

Main function.

Initialize the I2C driver.

Set the I2C Power mode.

Set the I2C bus speed.

Initialize MPL3115 sensor driver.

We do not need to call MPL3115_I2C_Configure() in this case as we are going to read samples on demand. Instead we directly write register settings for One-Shot Mode...

The code contained withing the braces illustrate steps to read one-sample. These can be repated at desired intervals to acquire more samples.

Keep checking the OST FLAG for completion.

Read raw sensor data from the MPL3115.

Process the sample and convert the raw sensor data.
