MultiWii

Hi,

I'm trying to start the engine using D2 and sending 5v to that pin but no luck so far.

please have a look at these images

Is there any documentation on how to start the engine and move the drone?

for the motor to start motor . .. the motor must be armed first .

please have a look at the stick configuration for motor arming and disarming

also , I am not sure about what you stated by : "sending 5v "

the esc in rc modeling are general speaking expecting a pwm signal .

Thank you for your reply,

Sorry I didn't mention that I'm trying to turn it on using my laptop. That diagram is very handy if I'm using a joystick to control it but I'm trying to send 5 or 0 voltage to the pins on the board and start the motors. So if you have any diagrams or some notes that can help me to send the commands to the pins to control the board that would be really helpful

I've got this diagram from multiwii website http://multiwii.googlecode.com/svn/trun ... iagram.png and it seems that I have to send some voltages to pin d2 but it doesn't do anything so I'm doing something wrong.

the d2 pin is connected to the throttle or ppm sum signal of the reciever .. in the first case this is a pwm signal and a ppm sum signal in the later .

you then have to apply a pwm signal to the d2 pin .. this signal is indeed at 5v .

if you want to activate the motor either individuali or by simulating the rc input from you laptop , you can use the gui than can be found in the MultiWiiConf folder , have a look at the "motor tab" and/or rc serial .

I couldn't find the motor tab on the gui but I've tried to sending PWM using python3 and it doesn't work probably because I'm sending 3.3 v instead of 5v.

Do you know the frequency and the ducty cycle that I have to use for PWM?

Thank you,
