Hi everyone, I want to take some analog values and I want to draw those values on graphs instantly. While analog values comes, graphs appear on the screen. How can I make this? Can you help me?
You'll need two programs -- a very simple Arduino sketch to run on the SAM3X, reading desired analog pins with analogRead and reporting them with Serial.print in a constant loop, then another on the i.MX6 side to take this stream of textual serial data (coming in on /dev/ttymxc3) and draw your graphs from that. Any necessary scaling, calibration, etc. could be handled by either CPU, as you prefer.
