The global variable index_marking is used by interrupt routine during index mark detection. The

interrupt just increases the value of this variable. The function cmd_do_detection requires four

parameters and it can work in two different ways. If the last parameter is lower than 0, the

function takes three first arguments and uses them as values taken from phase tables. In this

case, these phase tables are generated by the HalDetector program. Of course we need to

remember that these values will be later multiplied by power (pxms_ene), in this case arbitrary

chosen as 1024. Secondly, if the fourth parameter is greater or equal to zero it means that it is

an index of the phase tables which are already included in the driver. In this case first three

arguments are ignored. resentation of the function:

And here is some small example how to call cmd_do_detection:
