But I have mixed feelings about it. The chip has so much power but really cannot be realized in the featherwing format. With all of that memory, you could probably implement per-window framebuffers which really boosts performance in some applications (it is essentially required for Twm4Nx). > Yeah that is kind of why I have not bought that board. I have too many high performance platforms that I don't have time to support. If I am going to do that I would likely do the PineTab that someone sent me, but that is a very large effort that will probably have to wait until I have another large chunk of time away from work and feeling inspired. > The samd51 is a cool chip. It is really a samd21 update with a Cortex-M4F, but is still a little under powered at 120MHz. There is a 168MHz STM32F405 feather. What i.MXRT feather do you have? I guess I can Google that. > > I suppose that would be the Feather MIMXRT101. That would be a nice choice for the keyboard feather wing because it is high performance and the chip doesn't have native LCD anyway (so you wouldn't feel bad about that disuse of the LCD interface). I am actually cheating here a little since I could not find a imxrt feather, I have a teensy 4 board and one of these adaptors. https://www.adafruit.com/product/3200 I have not tested it yet, but I suspect it should work. I was digging around in my bins because I could swear I had ordered a STM32F405 feather, but I could not find it and my account does not show having ordered on. I think it would be great to support in general with the feather form factor, so when I place an order sometime in the next couple weeks I'll be sure to include one. I am happy to help get you hardware, I know it can be kind of expensive/hassle to get to where you are. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
