Hi! I wanted to see if I could control a brushless motor via the pwm output on the board, I was just wondering if I could get some help of how to go about it.
As far as I know, for a brushless dc motor, the paramaters are usually:
1ms = zero throttle
2ms= full throttle
I tried to modify the code from the PWM example but when I hooked up the motor all that I got was a fast beeping sound.
I have a turnigy9x controller with pwm output, and when I use it with a brushless motor i usually have to put the throttle on the zero position and then lower it down to the max position for a few seconds to get control of it. So do I have to do something like that? should I send a timed 1ms pwm followed by a 2ms to gain control of the motor? Anyone that was able to set up a motor with the pwm output if you could help me I really appreciate it.
It should be enough to send 1000us or less to make the ESC arm.
hi! I was able to make it work! I did a pwm pulse of 1000ms for a few seconds (than a music tone ringed on the motor) and afterwards I just tested the speed setting the values of the motor to1.1ms and 1.25 ms. Here is the code to anybody that may want to try it out:
PWM_OUTPUT = 2
SERVO_MIN = 1.250 #ms
SERVO_MAX = 1.750 #ms
pwm = navio.pwm.PWM(PWM_OUTPUT)
Well, I’m really new to these stuff and i have a basic question (or let’s say a stupid one), In which language you are programming? and there is another question on weather we have a default set for motors on the Navio+ ? Please answer
What are PWM parameters for RC switch (On / off state)?
The PWM frequency (edge up to edge up) is 20ms
PWM duty-cycle ON - 2ms
PWM duty-cycle OFF - 1ms
Frankly, I’ve tested Navio2 with these and RC switch does not work
Do you mean the RC switch that is used on Pixhawks? As a matter of fact Navio-2 doesn’t need those.
I do have flight Camera ECO FlyCamOneV2 - this is very old model 720x480 resolution which is pretty poor these days) but is has RC control feature.
When I connect to reciver I can start recording or if in picture mode - trigger taking picture.
I connect it to RC transmitter - switch channel - On/Off
I’ve been trying to test it in NAVIO2 using python code - with no sucess.
