Hello, I’m building a quadrotor helicopter and I really like the features of your servo controller. I’d like to reduce the number of channels from 8 to 4 and increase the pulse rate from 50hz as you specified to 100hz. This will give me better control and stability. I think this could be done by using four OR gates if the channels are pulsed one by one, correct? For example, channel 1 and 5 will be connected to one OR gate, and I would have to command both channel 1 and 5 to the exact same location, the single output from the OR gate would now would output identical high pulses but occurring twice as often, correct? I should also be able to accomplish the same using diodes with the anodes connected to the servo controller and the cathodes connected to a pull-down resistor and the servo, correct?
For this to work, I’ll need to know in which order the channels are pulsed. Is it simply from 1 to 8? or is it different? Looking at the schematics, it looks like all the firmware does is bit shift when the timer reaches whatever value the user sets, so I’ll assume it’s 1 to 8 (or 8 to 1, wouldn’t make a difference really).
