CX10-C camera button captures was created by Edwin

Hi all,

My cx10-c flies great with the cx-10 blue-A protocol, I just cannot figure out how to control the camera with my devo 7e. As I understand it the specific control has not been implemented yet in the protocol.

I have made three spi captures on the stock transmitter with my new logic analyser :

- binding of cx10-c to stock transmitter
- 3 times pressing the camera button (takes a snapshot to sd card)
- 4 times pressing the video button (alternately starts and stops the video recording)

the files are here : drive.google.com/file/d/0Bxf-446WD7Euand...OVE/view?usp=sharing

I do not have the skill to figure the protocol out but hope that someone can use these files.
Please note that is the first time using this logic analyser so if something is wrong please let me know.

Please export from the SPI decoder. The csv file should look like

Time [s]   Packet ID	MOSI	MISO
0.112485	0	0x3F	0x0E
0.112519	0	0x4C	0x00
0.112553	0	0x84	0x00
0.112587	0	0x67	0x00
0.112622	0	0x9C	0x00
0.112656	0	0x20	0x00

As hexfet says, your files are not exploitable, export from the spi decoder:

or save the whole capture:

Thanks for the feedback, just re-exported the files and also added the .logicdata saved files.

The files are here : drive.google.com/file/d/0Bxf-446WD7EuZVp...TUE/view?usp=sharing

Here's a test firmware for 7e, based on latest nightly:

There's a new CX10 protocol format option: "C", channel 7 controls snapshot, channel 8 controls video recording.

Please report

hi goebish,

just tested your build, set the protocol to type C and assigned channel 7 and 8 to a switch
- video on channel 8 works great it works both for toggling video on/off if pressed for a short time or it will record as long as the button is pressed for a longer time and stops when you let go.
- snapshot on channel 7 does not seem to do anything unfortunately...

Now the snapshot works as well, nice job! It does seem to lvc sooner but that just might be from all the testing

I will fully charge the quad and check once more

LVC has nothing to do with tx, it's only on rx side.

Correct, just tested it and it still does 2:30 - 3:00 of continuous video from full to flashing from low voltage (which also stops the video recording). That's the same as with stock tx.

thanks a lot !

Hi, I noticed that I made a mistake, I updated an old branch of mine instead of hexfet's latest one with q282 and mouldking protocols ...

Here's a correct one, can you test it please ?

I removed "C" protocol format option, it's useless, just use "Blue-A" protocol, I checked that the new flags don't disturb the "old" blue.
