Porting syma x5c-1 protocol to arduino

Hi, i try to porting the syma x5c-1 to arduino , i want to control the quad from my pc. Some one know how to do that ?
Or have code that do this may be with another protocol.
I use and arduino one and nrF24L01+.
Thanks
Ariel.

I modified the code for arduino it but not tested fully,,only binding.

Looks like you're on the right track.

I did it slightly differently in this project , changing the functions in NRF24L01.c to use the different hardware. It's not Arduino but may give you some ideas.

thanks

could you share your code with me?

The code is under the link posted above. Direct link to source files .

Hi:
Any address is a "legal address" to the rx_tx_address for X5C-1????
Thanks

Hi,
When i do binding the quads leds stop blinking until the symax_init2() function is called.
In this function the Channels address are calculated.
After this the leds blink slowlly again.
What's my problem? Some Sugestions?
Thanks

I never tried any value other than a2 for the first byte since all the captures were the same there. The other bytes didn't seem to matter.

The LEDs stopping indicates the quad's receiving your transmission. Maybe the new channel sequence is not being set or the new tx address in the radio before going to data phase?

How to calculate the channels from address?
Or you 'sniffs' RF?

The set_channels function determines the channels to use based on the last byte of the tx address for the x5c-1. The x5c uses a fixed set of channels.

The global chans holds the rf channels currently in use for both bind and data phases.

He has X5C-1,So this code covers also X5C-1 version?

Yes, the base protocol supports x5c-1. A protocol option is implemented to support x5c. The x5c variant uses a fixed channel sequence that does not depend on the tx address.

So if you select X5C from menu si not working with X5C-1,,..For that is the normal menu on SYMAx.,,right?

Correct. If you turn the X5C protocol option on, it will not work with an X5C-1 quad.

OK, finally works !!!!
My computer send commands to the Quad Througth the arduino.
Include video and pictures
Thanks Guys.

Oh, I was looking for the x12 control by arduino.
Could you share the code, if you don't mind?

I also ported the deviation protocols to Arduino and can control drones with smartphone.
I opened the codes and schematics.

Hope they will help.

hi I was wondering what you did step by step to make this project work

Hi,
Bit of help from those that have got this working pls.

I am fairly new to Arduino's and my coding is rusty but good enough to follow the flow of the program. I am a little stumped as to checking if the Arduino is actually communicating and what values I can enter to command it. I am new to the specific RC control methods as well so bit unsure of whether it is connected (don't think so) and then what values I need to enter to get it to respond, say throttle up.

I have uploaded the code and got it compiled in the Arduino ide. I think I have an X5C-1 rather than the normal X5C, XYMA in Red on top and X5C there as well.

The code in the Serial Monitor goes through 'symax_init' and 'symax_init1' then stops at 'symax_init2' after iterating through the 'SYMAX_BIND3' (is this where it is trying to check for an open channel and connect?)a lot of times. and if I enter a value in the Serial Monitor (not sure what values to enter - help here pls) I get the ;Received; and the parsed values.

The X5C itself only goes from very fast blinking initially to slow blinking (which makes me think it hasn't connected)

Some clues please to working out the connection and then if I can get that, how or more precisely what values I could send to get it to respond.

Any help welcome.
