Standard States
•
(qsm) initialize: Image Buffer
– (qsm) initialize activity: Create an image
buffer with “IMAQ Create” and then merge the reference into the data
highway.
•
– (qsm) initialize activity: Initialize a front-
panel control or indicator with an “Invoke Node.”
•
– (qsm) release: This state releases the front-panel action
buttons at the end of a task.
•
– (qsm) cleanup: Set the “Stop webcam flag” and close
an open file, for example.
•
– (qsm) shutdown: Release the state queue, free all
image buffer memory, and stop the while-loop.
•
– (qsm) schedule: Select a task to apply to the “en-
queue_states” VI and create a new task.
•
– (myRIO) initialize: Example activities such as send-
ing I2C data and setting up a PWM channel.
•
– (myRIO) cleanup: Example activities such as send
digital and analog outputs to inactive states, close PWM channel, send
I2C shutdown string.
•
– (myRIO) update ports: Example activities such
as reading and writing onboard devices, digital I/O, analog I/O, serial
buses, PWM, etc.
•
– (image) get: Walk through the details of this state, includ-
ing the Vision Acquisition Express VI and “IMAQ Symmetry” VI.
•
(image) get: Vision Acquisition
– (image) get: Use NI-MAX to create
and update the camera configuration files stored on the myRIO target;
