MultiWii

Thank you for your reply. I did some more research. TX and RX is transmission and reception, to control the copter. Since I plan on using XBee to control the copter (allowing me to have as many channels as I see fit, within reason), there won't be any interference between XBee and RX, right ? Many t...

I have a hard time understanding your question. And I am not an expert. But from what I know, both are firmwares, so no, you can't run them on one board at the same time. But I have seen boards compatible with both (which means that you have to choose one).

I already have the XBee pro modules, but I am interested in long range actually. So 3DR radios could be nice. I think regulations only allow me 433 MHz. I might have to buy a license, but I am unsure. Which RX would be affected? The RX is the reception of radio command? Can I use 3DR both for contro...

Thank you very much, both of you for your replies. I will take the Crius AIOP V2 with the ext Mag and XBee modules.
Now I need to figure out which motors / ESC / propellers to take.

Thank you for your reply I understood all that from the other post . On this thread, I would like to focus on the hardware. As you can se from my other question related to RC and TX module / FC communication, I am leaning more and more towards solution #1 or (probably) #2. I haven't decided yet wher...

Yes, you have the TX to RX to FC correct Now I understand! THank you for writing this sentence. Tx : transmission ; Rx : reception ; FC : Flight controller. English not being my native language, I have a hard time with acronyms. As for PPM/ PWM, I think I get it : PWM is PPM for one channel. PPM is...

Thank you for your reply. Please, could you just help me with : FC, TX, RX, RC RX abbreviations so that I can search for them? I do google a lot. Sometimes, a little help can make a big difference in terms of search times. It's hard to know what to search when you get a lot of coded language. And be...

Thank you for your really useful reply. I understand the difference between PPM and PWM. They look alike, but while PWM can have a ON/OFF ratio from 0 to 100 % PPM have an ON time from 1000 to 2000 µs located in a variable time frame (usually 20 ms). This allows for multiple signals to be sent withi...

Beretta: I got the same kind of reply. Unfortunately.

Looking for the keywords you gave me turned up a way to control servos and ESC for brushless motors.
Actually, I am more interested in how to control the multiwii board which controls the motors. What kind of signals is the multiwii board expecting from the receiver of the RF transmission ?

Thank you for your reply. I thought as much. Not that I am afraid of programming (I have a lot of experience with various microcontrollers). The issue is that I have a hard time finding any documentation about how the multiwii firmwares receives radio imputs. If I want to replace all the receiver co...

Thank you for your reply. I have been googling for a week on these topics. And I was indeed under the impression it was PWM signals, but I was unsure. My main issue are the acronyms. Like FC, ESC, SoR, Rx, etc. For instance, I still don't know what an ESC is…. For instance "SoR website" re...

Dear All, I was wondering how is the communication between a multiwii board and the receiver achieved? For instance, I read here: [url="http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=27109&aff=136356 "]MultiWii Lite V1.0 Flight Controller w/FTDI[/url] 6 input channe...

Hi All, I would like to build a quadcopter based on multiwii software, but I would need to modify it in order to add features, like triggering actions such as starting / stopping a camera, transmitting some data, executing routines in the code to modify the behavior, the flight plan, etc…). I see tw...
