Function Documentation

void LCBT_clearStats (   )

clear stats for LCB driver Returns: none

int LCBT_init (  int  latpAddr, int  useRedundantPath, LCBD  lcb )

inits LCB driver (which starts 2 tasks associated with driver) Parameters: latpAddr  LATp addr to assign to this board useRedundantPath  0=primary path, 1=redundant path lcb  lcbd driver handle is driver if already init (use LCBD_get()), if 0 will load driver Returns: 0=sucess else indicates errors in init This routine inits the LCBT module and optionaly load the LCBD driver. It must be called once after boot to setup the LCBT module for tests.

Here is the call graph for this function:

void LCBT_resetTest (  int  numReqPer  )

special test for reset fix on FpgaLat=0x5d Parameters: numReqPer  num of read for each of 4 part test Returns: nothing This test was developed to reproduce a problem seen with LatFpga < 0x5d on the cPci LCB board. The problem was that the discrete fifo's failed to be reset properly if there was no 20 MHz clock from the GASU (i.e. GASU was not yet powered up). This test requires USER INTERACTION to turn off/on the 20 MHz clock (usually by powering the GASU on and off). The fix in LatFpga=0x5d allows this test to run sucessfully without errors.

Here is the call graph for this function:

void LCBT_setOption (  unsigned int  mask  )

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

void LCBT_stats (  int  mask  )

print stats for LCB driver Parameters: mask  0=all,1=ISR,2=rst,4=evt,8=time Returns: none
