1.1.3.4.7 DRV_METROLOGY_IntegrationCallbackRegister Function

DRV_METROLOGY_RESULT DRV_METROLOGY_IntegrationCallbackRegister (
    DRV_METROLOGY_CALLBACK callback 
);

Allows a client to set a metrology integration event handling function for the driver to call back when a integration period has completed.

This function allows a client to register an integration period event handling function with the driver to call back when a integration period has completed.This function must be always called after DRV_METROLOGY_Initialize routine is called, since the initialization routine sets a NULL pointer to indicate no callback.

DRV_METROLOGY_Initialize must have been called before.

If successful, returns DRV_METROLOGY_SUCCESS. Otherwise, it returns DRV_METROLOGY_ERROR.
