8.2 Programming the Encoder Interface
Refer to section 6.2 for details on this interface and also the separate “Encoder Application Notes” under
“References” on page 2 of this document!
The encoder interface needs to be enabled prior to its use:
INTERFACE_MODE(ENCODER); // Encoder mode (RS232 disabled)
void enctest(void)
{
int Run=1,i=0;
char c;
print("\nEncoder Interface Test, press <ESC> to abort\n\n");
TRIGINP_NEG() ;
// turning direction anti clockwise
tpict(); // take image to end live mode
INTERFACE_MODE(ENCODER); // Encoder mode (RS232 disabled)
ENC_DISABLE_CNT(); // disable counter
//ENC_WAIT_N(); // wait one time for next 0+ pulse
ENC_WAIT_N_TRIG(); // wait every time for next 0+ pulse
ENC_ENABLE_CNT(); // enable inputs
ENC_WRITE_CNT(506); // set Counter value
ENC_WRITE_RELOAD(256); // set Reload value
while(Run)
{
tenable();
// wait for external trigger and take picture
while(!trdy()) // wait for image completion
{
if(kbhit())
// check for keyboard input
{
c=rs232rcv();
if(c==0x1B) // check for "ESC"
{
while(cancel_capture_rq());
Run = 0; // deleting last capture request
}
}
printf("encodervalue is: %08d \r",ENC_READ_CNT());
wait(0,50); // waiting time to slow printing
}
print("************* exposure ************** (%u)\n",i++);
}
INTERFACE_MODE(SERIAL);
// Serial mode (RS232 enabled)
vmode(0); // swtiching camera back to live mode
}
