HRTC - Hardware Real-Time Controller
1.13.1
Introduction
The
Hardware Real-Time Controller
(HRTC) is built into the FPGA. The user can define a sequence of operating
steps to control the way how and when images are exposed and transmitted. Instead using an external PLC, the
time critical acquisition control is directly build into the camera. This is a very unique and powerful feature.
1.13.1.1
Operating codes
The operating codes for each step can be one of the followings:
OpCode
Parameter
Description
Nop
-
No operation
SetDigout
Operation array on dig out
Set a digital output
WaitDigin
State definition array on dig in
Wait for a digital input
WaitClocks
Time in us
Wait a defined time
Jump
HRTC program address
Jump to any step of the program
TriggerSet
Frame ID
Set internal trigger signal to sensor controller
TriggerReset
-
Reset internal trigger signal to sensor controller
ExposeSet
-
Set internal expose signal to sensor controller
ExposeReset
-
Reset internal expose signal to sensor controller
FrameNrReset
-
Reset internal sensor frame counter
256 HRTC steps are possible.
The section
How to use the HRTC

How to use the HRTC
To use the HRTC you have to set the trigger mode and the trigger source. With object orientated programming
languages the corresponding camera would look like this (C++ syntax):
CameraSettings->triggerMode = ctmOnRisingEdge
CameraSettings->triggerSource = ctsRTCtrl
When working with
