2.1.4.7 DRV_MCMETROLOGY_IntegrationCallbackRegister Function

DRV_MCMETROLOGY_RESULT DRV_MCMETROLOGY_IntegrationCallbackRegister (
    DRV_MCMETROLOGY_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_MCMETROLOGY_Initialize routine is called, since the initialization routine sets a NULL pointer to indicate no callback.

DRV_MCMETROLOGY_Initialize must have been called before.

If successful, returns DRV_MCMETROLOGY_SUCCESS. Otherwise, it returns DRV_MCMETROLOGY_ERROR.
