I am using SPI to communicate with a US2066 controller interfacing a NHD-0420CW-AY3 display. Where can I find the maximum execution time for each of the commands enumerated in the display spec?

  Hello Brandon,

  Thank you for your interest in Newhaven Displays!

  The US2066 does not have any stated maximum execution time for the commands within its command set.

  The best we can recommend is, if you are experiencing timing issues with certain commands, is to add/increase a delay after the subject command sequences are sent to the display and check if the new timing is acceptable. If the new timing is not acceptable, increase the delay and check again.

  If you have any questions, don't hesitate to ask.

  Best Regards,

  Cody J.
