// Execute the list commands for initialization

// Marking procedure
// Waiting for list 1 to be not busy (load_list( 1, 0 ) returns 1 if successful, otherwise 0); if list 1 is not (no longer) busy:
// opening the list buffer for writing of list commands and setting the input pointer to the start of list 1
while ( !load_list( 1, 0 ) );
// In the following the list commands for marking point, square and circle are defined and transferred to the RTC
®
5 board.
// Marking the center point of the image field:
jump_abs( 0, 0 ); // Jump to center point
// A jump delay is automatically inserted after the jump.
laser_on_list( 5 ); // Turning on the laser control signals for 50 µs
// Marking a square around the center point:
jump_abs( -20000, -20000 ); // Jump to the bottom left corner of the square
// A jump delay is automatically inserted after the jump.
mark_abs( -20000, 20000 ); // Marking the left edge of the square
mark_abs( 20000, 20000 ); // Marking the top edge of the square
mark_abs( 20000, -20000 ); // Marking the right edge of the square
mark_abs( -20000, -20000 ); // Marking the bottom edge of the square
// The laser control signals are automatically switched on with the first mark command after a LaserOn delay
// and remain on for all four mark commands. A polygon delay is automatically inserted after the first three
// mark commands, each. Initiated by the following non-marking command (jump command, see below), a mark delay
// is automatically inserted after the last mark command and the laser control signals are automatically switched off
// after the last mark command and a LaserOff delay (afterwards standby pulses are outputted).
// Marking a circle around the center point:
jump_abs( 0, -10000 ); // Jump to the bottom edge of the circle
// A jump delay is automatically inserted after the jump.
arc_abs( 0, 0, 360.0 ); // Marking the circle
// The laser control signals are automatically switched on with the arc command after a LaserOn delay. Initiated by
// the following non-marking command (set_end_of_list command, see below), a mark delay is automatically inserted
// after the arc command and the laser control signals are automatically switched off after the arc command and a
// LaserOff delay.
// Defining the end of the list and the end of command transfer to the RTC
