Using RB-110 with SeaKing-70A Speed Controller

[rostamiani]

Hi
I'm a beginner and want to control SeaKing-70A with my Roboard RB-110.
Witch outputs should I use ?
How can I control the speed of the motor ?
I couldn't understand this datasheet

Thanks for your help

Any of the PWM / GPIO outputs on the Roboard (same pin is used for PWM or GPIO, depends on how you set the function of the pin) should be suitable.

You would control the speed of the motor in the same manner as you would control position of a servo, by adjusting pwm signal (typically using the RoboIO library available on the Roboard site, via SetPulse).

Based on the instructions for your ESC, I probably wouldn't bother programming the ESC via the Roboard unless you're feeling adventurous. I'd verify operation with a regular transmitter, but once you know the ESC is configured and works, it should only need the PWM signal that can be generated from the Roboard to change speed.

The ESC really isn't any different from a servo in how it is controlled, they both just take PWM signals to set position or speed. My advice, play with the settings. You won't fry an ESC like you would a servo if you're out of PWM range.
