Very slow SPI on ESP32?

Thanks for the links Gordon, I checked them out, and you're right -- that for sure is the right approach. In my case I'm using it with something called the M5 Stack ( https://m5stack.com ), and thats a pretty neat little box, with lots of stackable options. Its totally usable as is, just not for making games or say, realtime UIs. Also, I know Jumjum and Wilberforce are working hard on the current challenges of integrating the latest versions of the ESP IDF.. . :)
