I have to send a PWM signal to a controller module from an Arduino Uno. I'm not sure how to interpret the spec I've been given, and how to translate it into a PWM signal. The module is a Castle Creations Mamba Monster 2, if that helps.
The spec says the unit wants a 50Hz carrier, and the control is:
1500 microsec = idle 2000 usec = full forward 1000 usec = full reverse
I get that the period of the carrier is 20,000 usec but how does that relate to the control periods? Does it mean that for "idle" the PWM signal is high for 1500 usec and low for (20000 - 1500) usec?
Any help or insight is appreciated. Are there libraries that can deal with PWM in the given terms? Any good tutorials? I generally understand how PWM works, I just don't get the notation used here.
