Let me preface by stating how impressed I am by this open source community, it’s amazing.
I have bought a cube/Herelink combo where I aim to drive a boat with two 24V motors. I have not connected the motors yet, and am using an oscilloscope for measurement. I have traversed the setups and forums, but I seem to lack some fundamental connections in my mind to truly understand what’s happening on the servo rail and its setup.
My questions are as follows:
What are the connection between the RC channels and the channel modes? As far as I understand, each channel (RC1, RC2, …) can be linked to a signal pin on MAIN OUT. Each of these signal pins then deliver a PWM pulse. What are then these modes, what does it mean that they have different PWM numbers behind them (MODE1 - PWM 930-1230 etc)? Do different modes occur as I increase my PWM signal with the joystick?
Why am I locked to 5-10% duty cycle, and is it a way to surpass this? Since I’ll use boat motors I thought it best to use 0-100% PWM, but cannot for the life of me figure out how.
Following is my parameters, please tell me if something looks wrong:
MODE1-6: 0 (Manual) (What do these do anyway?)
RC1_OPTION: 51 (Manual)
RC3_OPTION: 51 (Manual)
SERVO1_FUNCTION: 26 (GroundSteering)
SERVO3_FUNCTION: 70 (Throttle) (Does not work, however RCIN3 works but is not recommended in wiki? Also restricted to low duty cycle.)
Also, setting SERVOX_MIN/MAX and RCX_MIN/MAX from 0 to 16000 or 20000 does not give me the full duty cycle as wanted.
A thousand thanks in advance.
