7.3.2.2.2 Trigger In Mode

Trigger In mode provides higher level of control to the user for displaying patterns. In this mode, the user controls when to display the pattern by sending an external trigger signal to the DLPC3479 controller. The DLPC3479 controller outputs a Pattern Ready signal to let the user know when the DLPC3479 controller is ready to accept the external trigger signal.

GUID-20201214-CA0I-Z1JZ-10TM-ZCZKH2VHFCWV-low.gif Figure 7-15 Trigger In Mode
  • DLPC3479 controller sets the Pattern Ready signal high to denote that the DLPC3479 controller is ready to accept Trigger In signal.
  • The user sends the external trigger input signal to the DLPC3479 controller to begin the display of the next pattern with tExposure (exposure time), tDarkPre, and tDarkPost (dark time).
  • Blue LED is configured to be ON for each pattern.
  • TRIG_OUT_1 (Pattern Set Trigger) is configured active high polarity and will have a minimum pulse width of 20 microseconds. TRIG_OUT_1 delay (tD1) is configured with respect to external trigger input (TRIG_IN).
  • TRIG_OUT_2 (Pattern Trigger) is configured active high polarity and stays active during the pattern exposure. TRIG_OUT_2 delay (tD2) is configured with reference to the start of each pattern exposure.
