I have a project in which several Arduinos will be running independent programs. I would like to use an Arduino Mega as the main controller. It will receive input from a variety of switches, as well as data input from 2 Arduino Unos and 3 Arduino Nanos.
Each Nano will run a basic collection of switches and LED displays.
Each Arduino Uno will be connected to a 2 axis joystick and will have several button inputs from the joystick, as well as several 7 segment Led displays and several LED indicator displays.
The Mega would need to gather information of at least 16 bytes from each slave at highest possible speed, and be able to transfer at least 16 bytes to each slave at the same rate. I would also need the clock signal for all devices to default to the Mega.
What would be the best way to begin setting up the program logic to get these boards to interact in a smooth manner without a lot of lag in communication between boards?
Also, what would be the limitations on speed with this sort of com setup between the boards?
If more setup or function information is needed I can add description, just didn't want this post to be overly lengthy.
running independent programs
.... your description says otherwise
