Function Documentation

diff_p_isr()

void diff_p_isr

(

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.

Here is the caller graph for this function:

main()

int main

(

void

)

Main function.

Initialize INT1_DIFF_P 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 DIFF_P sensor driver.

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

Configure the DIFF_P sensor.

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

Check for event ready bits from the DIFF_P.

Explicitly clear the Status Bits.
