Macro Definition Documentation

◆ MMA865x_ACCEL_DATA_SIZE

#define MMA865x_ACCEL_DATA_SIZE (6) /* 2 byte X,Y,Z Axis Data each. */

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 the MMA865x sensor driver.

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

Configure the MMA865x sensor driver with No FIFO mode.

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

Read the raw sensor data from the MMA865x.

Convert the raw sensor data to signed 16-bit container for display to the debug port.

◆ mma865x_int_data_ready_callback()

void mma865x_int_data_ready_callback ( void * pUserData )

This is the Sensor Data Ready ISR implementation.

This function sets the flag which indicates if a new sample(s) is available for reading.

Parameters

[in] pUserData This is a void pointer to the instance of the user specific data structure for the ISR.

Returns: void There is no return value.

Constraints:: None
Yes

Set flag to indicate Sensor has signalled data ready.
