Function Documentation

static i2c_status_t data_sink ( uint8_t  rxData)
static

This callback function is used by the I2C slave IRQ handler to deliver the

byte it received to the application. If there is no room in the buffer, the

callback function will report kStatus_OutOfRange.

Parameters
[in]rxDataThe byte of data from the driver to store in the applications buffer.
Returns
kStatus_Success or kStatus_OutOfRange
static i2c_status_t data_source ( uint8_t *  txData)
static

This callback function is used by the I2C slave IRQ handler to supply the

byte it transmitted by the application to the I2C driver. If there are no more

bytes in the buffer, the callback function will report kStatus_OutOfRange.

Parameters
[out]*txDataThe byte of data from the applications buffer to

return to the driver.

Returns
kStatus_Success or kStatus_OutOfRange
int main ( void  )
static void on_error ( i2c_status_t  error)
static

This callback function is used by the I2C slave IRQ handler to report an error

condition. If the error is an OutOfRange error, the appropriate buffer index is

reset.

Parameters
[in]errorThe error reported by the driver.
Returns
nothing
