Function Documentation

◆ main()

int main ( void )

Main function.

Initialize the MCU hardware

Initialize RGB 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 MMA9553 sensor driver.

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

Configure the MMA9553 sensor driver with 30Hz Mode settings.

Initialize streaming and assign a Stream ID.

Populate streaming header.

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

Read the raw sensor data from the MMA9553.
