Hi all, My first post here! I'm not new to Arduino, but everything I've done so far is very basic. Right now I'm in a more complex project using an Arduino to do the following things:
- It should read the pulse width of four PWM signals from a RC receiver type PPM. These signals are like the figure below (20ms frequency and maximum pulse width 2ms, out of phase with each other) (servos are not important, and the frame time is 20ms).
- Manipulate that data to convert the read signal into -100% + 100%.
- Send the manipulated data to Ethernet.
What I want to know is: Is it possible to do with an Arduino Board? Is Arduino Uno + Ethernet Shield the best option? Or is better Arduino Mega + Ethernet Shield? Is it possible to read the four PWM signals in less than 20ms?
Than you very much in advance!
