Hi, I'm using Arduino IDE on my pcDuino v1
I'm a beginner with Arduino boards or pcDuino, I would like to record signals on sd card or usb key for example.
My program works but I would like to increase the data capture frequency and the function "analogRead" is a little too slow.
I tried to read on /proc/adc5 without using analogRead but I got the same time.
For one capture (+ write on buffer) I get an average of 21-24µs with a data capture frequency of 10 kHz
Do you know a method to get faster values ?
