Bandwidth for USB GPIO: 8 kHz if you're lucky and there are no other devices on the same controller. Bandwidth for the direct GPIO: up to tens of MHz.
- TheRealPomax 6y agoSo, not exactly a problem for anyone who wants to use a raspi but also windows? If you need MHz of GPIO speed, you're basically in arduino land now, and raspi+win or a minipc+win doesn't make a whole lot of sense. But hey, you can you also just connect an arduino to the minipc and get the best of both worlds.
- vardump 6y agoYou can achieve MHz GPIO speed with RPi running Raspbian. There are FIFOs and DMA. The days of bitbanging are long since gone.
- TheRealPomax 6y agoOf course you can, but this article is about folks who want to use Windows (for whatever reason). If you want to use "the raspi" as a controller, there is zero reason to look for a way to put Windows on a tiny board. A standard raspi already does what you need.
