Function Documentation

int LCBT_init (  int  latpAddr, int  useRedundantPath )

inits LCB driver and start 2 tasks associated with driver Parameters: latpAddr  LATp addr to assign to this board useRedundantPath  0=normal path, 1=redundant path Returns: 0=sucess else indicates errors in init This routine inits the LCBT module. It must be called once after boot to setup the LCB driver for tests. (currently there is no way to shut down the driver, therefore to change the above parms, like latpAddr, one needs to reboot and call with new parameters. If this is called multiple times, the current LCB driver will create multiple tasks trying to listen to the ISR)

Here is the call graph for this function:

void LCBT_setEventWatermarks (  int  eventQWatermark, int  eventBuffWatermark )

Set watermarks to cause interrupts from EventQueue and EventBuff fifos. Parameters: eventQWatermark  0=75% full, 1=50% full, 2=25% full, 3=NotEmpty eventBuffWatermark  0=75% full, 1=50% full, 2=25% full, 3=NotEmpty Returns: none Sets up watermarks that cause interrupts from EventQueue or EventBuff. The EventQueue can hold 1024 event descriptors and interrupts on the number of events currently in buffer. The EventBuff holds up 516K of data and interrupts on the amount of event data availible (as oppsed to the number of events)

void LCBT_setOption (  unsigned int  mask  )

set test option mask, see LCBT.h for values Parameters: mask  mask of tests options Returns: none
