Hi, I'd like to know how fast can the Arduino due read its digital pins using standard Arduino read write(cause I've never programed arm)? I have an adc that has a sample rate of 75 MHz that I am reading with an fpga that will get the some of n samples, and pass the value to 13 + drdy digital pins and I want the Due to read those 14 bits and send the data to my computer via the high speed usb. I hope that my only limit is the high speed usb's 480Mbit/s because the faster I can send data to my computer via usb the less samples I have to add together.
thanks, sorry if I wasn't very clear
