7.1.4 Example Code (C)
The following example C source code shows the
commands of a simple laser scan application.
A point, a square and a circle are marked in
CO
2
Mode. Here it is assumed that the
RTC4 Compatibility Mode is activated.
The code must be included in a user program, see
Chapter 6.2.5 ”Example Code (C)”, page 100.
// Scan system initialization
// Loading and assigning a correction file
ErrorCode = load_correction_file( 0, // initialize like " D2_1to1.ct5 " ,
1, // table (#1 is used by default)
2 ); // use 2D only
if ( ErrorCode )
{
printf( " Correction file loading error: %d\n " , ErrorCode );
free_rtc6_dll();
return;
}
select_cor_table( 1, 0 ); // assigning correction table #1 to scan head connector #1 (default)
// Laser control initialization, see Chapter 7.4 ”Laser Control”, page 184.
// Setting the CO
2
Mode
set_laser_mode( 0 );
// Setting and enabling the Signals for “Laser Active” Operation
set_laser_control( 0x18 ); // All Laser Control Signals active-LOW (Bit #3 and #4)
// set_laser_control must be called at least once to activate Laser Control Signals.
// Later on enable_laser/disable_laser would be sufficient.
// Opens List 1
set_start_list( 1 );
// Setting the standby pulses
set_standby_list( 800, 8 );
// In RTC4 Compatibility Mode the standby parameters are specified in units of 1/8 µs.
// The RTC6 board multiplies the specified values by 8 to convert them to
// integer-multiple of 1/64 µs. Half of the standby output period = 100 µs.
// Pulse length of the standby pulses = 1 µs.
// Timing, delay and speed preset
// Setting the Scanner Delays (see Chapter 7.2.2 ”Scanner Delays”, page 147).
set_scanner_delays( 25, 10, 5 );
// Jump Delay = 250 µs (specified in [10 µs])
// Mark Delay = 100 µs (specified in [10 µs])
// Polygon Delay = 50 µs (specified in [10 µs])
