Function Documentation

main()

int main

(

void

)

This is the The main function implementation.

---

This function invokes board initializes routines, then then brings up the sensor and finally enters an endless loop to continuously read available samples.

Parameters

[in]

void

This is no input parameter.

Returns

void There is no return value.

Constraints:

None

No

Initialize the MCU hardware.

Initialize MMA865x pin used by FRDM board

Initialize RGB LED pin used by FRDM board

Initialize the I2C driver.

Set the I2C Power mode.

Set the I2C bus speed.

Initialize MMA865x sensor driver.

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

Initialize the pedometer

Configure the pedometer

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

Read the INT_SRC from the MMA865x.

Display that a Motion event has been detected.

Read the Output from the MMA865x.

Convert the raw sensor data for feeding to pedometer algorithm.

Execute the pedometer Algorithm
