Hello. Does anyone know, roughly, what the refresh rate of the 3216 Sure Electronics display is? From what I could gather from the pagehttp://scuola.arduino.cc/en/content/controlling-sure-electronics-3216-led-matrix-arduino-uno
and from the Sure Electronics manual, it has display buffer. How often are the actual LEDs updated from this buffer? And are they strobed, or do they stay on until the next update?
What about transfer of data to the display buffer? From the above page, it looks like you need to transfer 14 bits/LED. How long does it take? How fast can you transfer the data?
Thanks a lot for any help on this.
P.S. If anyone is wondering why we're looking for fast refresh and transfer rates, let me say what the application is: to study human vision during saccades, which are very fast eye movements. The eye moves so fast, in fact, that 1000 Hz or higher update rates are required.
