If someone can point us to a screen that would work with gray scale I’m totally open to trying to build a prototype with it. But I’ve looked for about 3 years and not been able to come up with anything. The vertical sync pin is actually available on the ssd1603 controller but it’s not broken out to the flexible pin connector.
I’ve asked the factory if it is possible to change this on several occasions but the minimum order quantity for this customization is to be a million units. I’ll keep trying but color is easier to do than grayscale for the reason the screens actually exist.
Custom LCD might be an option but that also has a very high minimum order quantity and I’m not sure we could meet that. And then you lose the bright crisp OLED display that I think makes Arduboy so special.
My guess is we will do another black and white version with the SAMD21 and SD card later this year and then color in 2018.
Thanks so much for the feedback it’s super helpful to hear from all of you!
