This example is only meant for the PROPixx as it is the only device able to display stimuli at 480 Hz. To do so, we limit our resolution to 1/4 of the screen to display 4 times faster. Indeed, your stimulus needs to be created as follow:
|
Quadrant 1 |
Quadrant 2 |
|
Quadrant 3 |
Quadrant 4 |
One frame at 120 Hz will represent 4 frames at 480 Hz on the PROPixx, and each of those 4 frames must be put in order in the quadrants 1, 2, 3 and 4.
Python
from pypixxlib.propixx import PROPixx
my_device = PROPixx()
my_device.setDlpSequencerProgram('QUAD4X')
my_device.updateRegisterCache()
# You can now send you stimulus at 120 Hz to be displayed at 480 Hz!
