Function Documentation

void XVprocSs_LogDisplay

(

XVprocSs *

InstancePtr

)

This function will read and print the entire event log.

Parameters

InstancePtr

is a pointer to the XVprocSs core instance.

Returns

None.

Note

After reading out all events, the log will be empty.

u16 XVprocSs_LogRead

(

XVprocSs *

InstancePtr

)

This function will read the last event from the log.

Parameters

InstancePtr

is a pointer to the XVprocSs core instance.

Returns

The log data.

Note

The read is "destructive" in the sense an event may only be read once, the read pointer then advancing to the next entry. After reading all the events (see routine XVprocSs_LogDisplay), the log will be empty.

void XVprocSs_LogReset

(

XVprocSs *

InstancePtr

)

This function will reset the driver's logging mechanism.

Parameters

InstancePtr

is a pointer to the XVprocSs core instance.

Returns

None.

Note

HeadIndex == TailIndex means that the log is empty.

void XVprocSs_LogWrite	(	XVprocSs *	InstancePtr,
		XVprocSs_LogEvent	Evt,
		u8	Data
	)

This function will insert an event in the driver's logging mechanism.

Parameters

InstancePtr	is a pointer to the XVprocSs core instance.
Evt	is the event type to log.
Data	is the associated data for the event.

Returns

None.

Note

The DataBuffer is circular. If full, new events will overwrite oldest events.
