Alguien a fabricado luces para blue robotic.
Yo probé con varias tarjetas controladoras de del por pwm pero no me resulta poder controlar las luces.alguna ayuda
Hi @vapy
bienvenido a los foros!
The Lumen Lights are controlled with a standard Servo PWM signal.You should be able to adjust their brightness with a servo tester like this.
Are you trying to use the lights with the BlueROV2?
Si quiero hacer 2 luces y usarlas con el blue rov .probé con un controlador led por pwm .pero no resulta .no puedo controlar las luces
Hi @vapy -
Can you share pictures of how you’ve connected things? Do the lights turn on if you connect the yellow signal wire to your battery (with the red power wire?)
Please use our support form to report a problem with a product if the issue persists.
Hi @Vapy
Not sure what is happening there, but I would guess you’ve damaged the Lumen by using it with non-standard, driver rather than the Blue Robotics solution. You can buy just the PCB components of the lumen!
El led funciona y enciende pero no puedo ajustar la intensidad
Hi @Vapy
It sounds like you don’t have a working driver board that supports adjusting the brightness! Blue Robotics obviously cannot provide advice on a product that from another vendor with unknown specifications - hence the recommendation to use the intended electronics and not whatever alternative you have sourced.
Hola tengo problemas con las luces me aparece desactivado
Hola @vapy,
I’m not sure why QGroundControl is not allowing you to configure your lights properly. Can you specify which QGroundControl version you’re using, and what kind of flight controller board (e.g. Pixhawk, Navigator, etc)?
If necessary, you should be able to configure the underlying SERVOn_FUNCTION parameter directly to RCIN9 for Lights1 control.
The controller PCB within our Lumen lights expects a servo-style PWM signal, and converts 1100-1900 µs duration pulses into 0-100% brightness control of the LED daughter board, with an exponential brightness curve to provide more intuitive and useful control.
Other controller/driver boards may expect alternative input signal types, like a PWM signal with 0-100% duty-cycle (time high vs time low) to directly correspond to the output brightness.
Hola tienes algúna información de cómo es el procedimiento para calibrar el compás del blue rov .lo estoy haciendo y después de calibrar me arroja error .tal ves lo estoy haciendo mal
Hi @vapy -
With QGround Control not open, please try to calibrate the compass via the [Vehicle Setup menu.] (BlueOS Documentation)
Alternatively, you can use QGround Control.
hola amigos del grupo.
les quiero hacer una pregunta?
estot tratando de hacer funcionar un blue rov que tiene una raspberry pi 3 y una pixhawk 2.4.8 y este rov funciona bien .
lo que estoy tratando es de instalarle otro tipo de motores (teledine de 48 volts dc y se controlas con ± 5 volts de control para el giro y la velocidad.
pero creo que la pixhawk no tiene esas salidas y creo que nececiti una tarjeta que me convierta la salida de la pixhawk a ± 5 volts cuando accione la palanca del joystike .si alguien tiene algun dato ta que tarjeta puede servirme o orientarme como hacerlo.
gracias saludos
Hi @vapy
Converting the Pixhawk PWM output to be a +/- 5V DC signal to control a Teledyne thruster is quite challenging! You could read the signal from the pixhawk with a microcontroller like an Arduino, and create the necessary output with the correct circuit.
This would make the problem about creating -5 to +5 V from a 0 to 5V DC output. Your Arduino code would read what servo-PWM is being sent to it, and send a PWM signal of 0 to 5V to the appropriate location in the circuit.
I’m not enough of an electrical engineer to recommend the best circuit, but do know you’ll need to use an IC like 7660 or MAX232 to generate a -5V rail if you only have a single 5V supply. I’d search for information on how to to convert the Arduino’s 0–5V PWM output to -5V to 5V, use a combination of a resistor divider and an op-amp.
Best of luck!
