Motors don't stop when RC receiver if turned off

7 years 6 months ago #29527818 by marcusbarnet
I\'m using a RC Futaba receiver connected to my HDC2450 controller in order to move two DC motors.

Everything works great, but I realized that if I turn off my transmitter (a Futaba T8J) while I\'m using it to move the motors then they continue to move with no control!

To gain control again, I have to switch on my transmitter again or to use my mushroom button to cut off the batteries.

Is it possible to fix this problem by setting something in Roborun utility? I do not know, may be something like watchdog for USB data.

Or I have to use a script to avoid this problem?
If yes, do I have to check if digital inputs are inactive and if yes stop the motors?

Can you help me, please?

If this controller is connected to roborun, look at the top of the browser in the run tab. With the mute button at the middle left of the browser selected and the remote on, the Status LED for Pulse should be red. If the remote gets shut off, then the Status LED for Pulse should turn off and be gray again.

If the Pulse LED begins to pulse (Flash on and off repeatedly), then the receiver is still feeding in pulses to the controller even without the remote being activated.

If this is the case, you will need to tune your receiver output so that it stops sending pulses after your remote gets turned off.

Thanks you!

I solved it, it was my transmitter configuration.
