Sik 2.x in 3DR radio

Dear all,  Anybody tried the sik 2.x in 3dr radios in order to use in multipoint configuration? I´ve read this topic:    But I think that the firmware posted is for the RFD900, so I´m not sure if it will work, anybody has the firmware compiled por the hm-trp radios?    Thanks  Jesús  See More

Ublox to nmea converter

Posted on October 26, 2009 at 4:44am 3 Comments

I want to use a ublox gps for two item. A paparazzi autopilot, that need a ublox gps, and a osd that need a nmea code gps. And I want to use only one gps. Is there any kind of ublox code to nmea converter? O something like that?

Paparazzi help!

I´m very interested in the paparazzi uav ans the booz (quadcopter). But I have some questions that I wish that anybody could answer it.

1st- It´s possible to use the modem like a rc systems, for example connecting a gamepad to the laptop?

2nd- Which knods of sensor can be connected to the analog inputs? Are there code prepared for that?

3rd- Is ther a "newbie" guide to start in the paparazzi uav?

4th- It´s possible to control the booz with the laptop?

5th-… Continue

So the very first thing I did was add the software serial line. I used a library that can be found here:
Next, we created an array in RAM for the WPs that we upload. We decided that writing to the EEPROM while flying might be a bad idea, so we have actually two sets of WPs, so we needed a flag to tell the AP where to read the WPs from.

The biggest challenge that I faced was simply creating a command buffer and filtering out bad data on the software serial line.

An alternative would be to use an Arduino Mega which has 3 dedicated serial lines, which means you could read off it much faster.

Good luck!

Hola Jesús!

Yo soy alumno de la ETSIA, también. Estoy muy interesado en estos temas y tengo algunos proyectos en marcha o en mente.
Si algún día te apetece hablar de estos temas, no dudes en ponerme un email y nos vemos por la escuela.

Un saludo!

I tested it but never flew it with the gamepad since I got my radio equipment to work.

The airborne code can be found on svn under the name of joystick.c and the GCS version for the joystick is somwhere on SVN too, IIRC.

Yep, it's only for the AUTO1 and AUTO2 modes but it could be altered quite easily to work in all modes.

It'd be quite possible to use the ppz completely without MANUAL-mode and with the gamepad/joystick only, I'd recon. The only thing that you'll have to take into consideration is that you have to have your PID gains tuned before you attempt to fly with only AUTO1 and 2. But I take it you have your Paparazzi tuned for your A/F already so that shouldn't be a problem? Another thing that I'd do if I were you would be to make use of all the joystick buttons and throttle so that you could have complete control over all the functions of the Paparazzi without having to use mouse or keyboard in between. I.e. you could use the joystick buttons to change the flying mode of the PPZ etc. It'll require some programming, I think, but shouldn't be too hard to accomplish.

Hi Jesus,

I´m trying to do something similar to you, I mean control an APM 2.5 with a SCB (beagle).

How do you connect the the APM from the BeagleBoard? Do you use USB-TTL serial cable plug on the telemetry UART port? if so, where do you bought it?

thanks, regards.

Hello Jesus,

Thank you for you interest in my thesis.  You can access the PDF of my report through this link and you can also get to it via the github repository which I placed a link to in my original blog post.

Thanks Brian!!!

I´m going to do some experiments :-)

Hello, Jesus. What do you mean by control architecture? control algorithm? Of course PID.

Buenas Jesús, 

he estado leyendo la publicación en la que preguntas cómo se crean modos de vuelo nuevos en arduplane. Para mi trabajo final de grado tengo que realizar unas modificaciones a uno de los modos de vuelo (o crear uno nuevo) con diversos fines, y creo que la experiencia que pudiste haber adquirido mediante la realización de ese proyecto me puede ser realmente útil.

Por lo tanto me gustaría saber si me podrías acceder a toda esa información y así, permitirme avanzar de una mejor forma en mi proyecto.

Un saludo y gracias de antemano!

Fede Paredes.
