Function Documentation

boolean ec_configdc ( void  )

Set DC's of all slaves to sync with the first, measure propagation delays.

return DCfound

Locate DC slaves, measure propagation delays.

return boolean if slaves are found with DC

void ec_dcsync0 ( uint16  slave,
boolean  act,
uint32  CyclTime,
uint32  CyclShift 
)

Set DC of slave to fire sync0 at CyclTime interval with CyclShift offset.

Parameters:
[in]slaveSlave number.
[in]actTRUE = active, FALSE = deactivated
[in]CyclTimeCycltime in ns.
[in]CyclShiftCyclShift in ns.
void ec_dcsync01 ( uint16  slave,
boolean  act,
uint32  CyclTime0,
uint32  CyclTime1,
uint32  CyclShift 
)

Set DC of slave to fire sync0 and sync1 at CyclTime interval with CyclShift offset.

Parameters:
[in]slaveSlave number.
[in]actTRUE = active, FALSE = deactivated
[in]CyclTime0Cycltime SYNC0 in ns.
[in]CyclTime1Cycltime SYNC1 in ns. This time is a delta time in relation to the SYNC0 fire. If CylcTime1 = 0 then SYNC1 fires a the same time as SYNC0.
[in]CyclShiftCyclShift in ns.
