Control Receiver With Assembly

[Vasco - PORTUGAL]

hello,

I want to construct a program in assembly,to control one electric airplane.

I send to receiver one code (protocol) , exemple 1110 1010 1010 1011 and receiver must be responding ,but I don´t know what protocol is used to control the receiver ( lexors - nano4 35mhz ) ! Can you help me please?

:)

Re-phrase your question. I can't follow what it is you want from us.

VASCO do you mean you want to make a unit that sends the code receiver? Ie you want ot make a transmitter.

If your having trouble putting your question in English, you might want to try this site: AltaVista - Babel Fish (http://babel.altavista.com/). You can use this site to translate from Portugese to English. It's not so great with technical terms, but it might be better than trying to do the translation yourself.

Hello, SORRY about my ENGLISH ....

I have a sender plaque that I've made, and it sents signals toa receiver, through a program that I've made in "assembly", but I don't know what the protocol requieres for the receiver.

For example, for a code sent to the receiver, 1110 0000 1001 1101, are necesary 4 channels of 4 bits, it might be the first channel 1110 for the servo mechanism 1? 2? 3? engine? and which is the protocol required to turn 1110 or 0001 or 0010 or.... ??

what I need to know exactly is which protocol is used to sent ..( servo 3, servo 1, servo 2,engine..the order!!!) and which is the code for each channel.


HELP ME....

If you don't already have a good understanding of PPM receiver technology, this website and oscillograms may explain some of the encoding methods.

Thks , but hi have an lexores nano4-35mhz receiver and i want to control them with a RFcontroller made by me , trough my pc.
I know the protocol to control the servo but i don´t know the format of the RFsignal to control the diferent servos.

Vasco,

Have you read the post above? The link explains what the PPM signal consists of. That PPM signal modulates the frequency of the RF carrier sent from the antenna of your transmitter.
