Function Documentation

main()

int main

(

void

)

Main function.

Initialize the MCU hardware.

Initialize INT1 MPL3115 pin used by FRDM board

Initialize GREEN LED pin used by FRDM board

Initialize the I2C driver.

Set the I2C Power mode.

Set the I2C bus speed.

Initialize the UART driver.

Set the UART Power mode.

Set UART Baud Rate.

Initialize the MPL3115 sensor driver.

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

We do not call MPL3115_I2C_Configure() in this case as we are going to read samples on demand. We explicitly only enable ISR settings.

Initialize streaming and assign a Stream ID.

Populate streaming header.

Clear the data ready flag, it will be set again by the ODR CB.

Read raw sensor data from the MPL3115.

Convert the raw sensor data to signed 32-bit and 16-bit containers for display to the debug port.
