I have to do a project in which I need to use microcontroller. The choice is mine which to use. The micocontroller must be compatible to main two process. 1. I have to do FFT analysis and get the reading. (Too much data, I guess memory should be concerned also) 2. SPI interface too send those data to another device.
My question is which controller have inbuilt best and easy library to conduct these operation and can do it faster with high efficiency. i do have a bit experience with microcontroller but selecting one is confusing. I did use stm32 and arduino. I will really appreciate the help in this regards.
