GPI Start Frame Event

The GPI start frame event feature specifies the event type that triggers the start of a frame in a line scan camera. Most events involve signals on the general purpose input (GPI) pin specified by the GPI start frame mode feature.

Value options:

• Rising_Edge: The input signal's rising edge triggers the frame.
• Falling_Edge: The input signal's falling edge triggers the frame.
• Encoder_Frame_Divider: The internal encoder frame divider counter triggers the frame.
• Pulse_High: While the input signal is high, the internal encoder frame divider counter triggers the frame.
• Pulse_Low: While the input signal is low, the internal encoder frame divider counter triggers the frame.

GPI_Start_Frame_Event node

• Access mode: Read/Write
• Node type: Enumeration

You can use the eSDK API functions to:
