How to use I2C2_SendAcknowledge()

[BlackNight]

For example:

res = I2C2_SendAcknowledge(myDevice, LDD_I2C_ACK_BYTE);

From the help text:

SendAcknowledge - This method send acknowledge/not acknowledge for current receiving byte. This method is available only if control acknowledge bit is enabled.

ANSIC prototype:

LDD_TError SendAcknowledge(LDD_TDeviceData *DeviceDataPtr, LDD_I2C_TAckType AckType)

• DeviceDataPtr: Pointer to LDD_TDeviceData - Device data structure pointer returned by Init method.
• AckType:LDD_I2C_TAckType - Specify type of receiving byte answer.
  LDD_I2C_ACK_BYTE - The values of acknowledge bit correspond to successful byte receiving (receiver send ACK bit value automatically according the I2C specification).
  LDD_I2C_NACK_BYTE - The values of acknowledge bit correspond to not successful byte receiving (receiver send NACK bit value and terminate reception).
• Return value:LDD_TError - Error code, possible codes:
  ERR_OK - OK
  ERR_DISABLED - The device is disabled.
  ERR_SPEED - This device does not work in the active clock configuration.
  ERR_PARAM_MODE - Invalid acknowledge type answer.
