JJRC1000 questions

I'm a noob with ini files.

Below is a bit of the .ini for my JJRC1000. Channel 5 makes the LEDs turn on or off. If I remove all the lines for channel 5 from my ini file (and give it no information about channel 5) then once bound the quad's default behavior is for the LEDs to slowly blink on and off. So therefore: the quad has three settings for its lights: on, off, and blink.

Question #1: I would like for the quad to blink like that when it is in flip mode (controlled by channel 6 and HOLD0). How could I do that? How can I make the lights blink on purpose? What command do I need to send to channel 5? Is it done with scalar? Can someone explain?

I'll take a shot at this... For me, this is a great challenge question, and I hope others can chime in.

For this device, I don't think we can really know the answer until you figure out which Channel 5 value setting changes the lights to blink. In other words, with FMODE1 set on, channel 5 is 100, and the lights are on; likewise FMODE0=channel 5 at -100, lights off. Do the lights blink if you set FMODE1 to send a different value? Presuming you know that value, setting up the mixer should be no problem, although I had to dig up MWM's great tutorial "Writing a deviation TX model".

You may be able to determine the required value by modifying your current channel 5 to this. If it doesn't work, change the offset to -50 or -150... sometimes you are shooting in the dark (unless you can get your hands on the SPI traces!):

Presuming a value of 0 gets the blinking lights, you can use this with a mixer to get HOLD0 (your flip switch) to modify the output of Channel 5. I think this will work to send a 0 value, at least it does in the emulator!

Let us know if it works.. I think you'll have to have your lights turned ON (FMODE1) then when you engage HOLD0 the value on Channel 5 goes to 0 and they blink. If FMODE0, then the lights stay off. If you want the blinking no matter the setting of HOLD, that's not how its working now.

I'm still trying to learn these more challenging mixers too

If you want to have the lights blink whenever you are in Flip mode, whether you have the lights turned on or not, you need a slightly different mixer. This approach works on my JXD392 (v2x2 protocol), although of course YMMV! Need I mention it is always good to test these with the propellers removed?

While tinkering with the offsets, I saw another behavior I didn't know about. With the JXD392 the blink speed is a function of the value you set! In this code I've set it to 99, but it seems to handle any value from -99 (extremely slow) to 99 (very fast). The value of 0 gives me the blink speed that happens when the TX is turned off, so I don't want to use 0 for my flip indication. In my flight testing I found that fast blink (99) is used for Low Voltage indication; this probably isn't a problem if you fly timed sessions, but you should be aware of the conflict.


Let us know how this works with your JJRC1000.

[channel5]
template=complex
[mixer]
src=FMODE1
dest=Ch5
[mixer]
src=HOLD0
dest=Ch5
switch=HOLD0
scalar=99
curvetype=fixed
usetrim=0

Thanks Jeff, that worked! The help is much appreciated. When I hit the HOLD switch flip mode now comes on, and the lights flash. But I have a new problem now: When I hit FMODE to switch rates, the LEDs on the quad go off. Is there a way to make it so FMODE doesn't ever change the lights?

More importantly, I've read mwm's manual but I'm still struggling a bit to understand .ini files. Can you explain to me (like I'm 5 years old) how what you wrote works? Here's what I understand of what you wrote, part by part:

= It is taking the value of the FMODE switch and sending it to Ch5 (lights), it will either send -100 or +100. I'm confused about why this is required for this situation, but I tried taking it out and it messed things up.... ?

= Then it is also taking the value of HOLD and sending it to Ch5.

= Then it is saying if the HOLD switch is at the 0 position then set the value of Ch5 to 99. Then it has the bit about usetrim=0 which I don't understand.


...am I close?

I'm wondering, is it already possible to enable the headless on the jjrc1000 mode using deviation?

Yep, I captured the Headless command for V2x2 protocol some time ago and Victzh updated the protocol.
Please, check the V2x2 protocol thread under Protocol Development sub forum, but if I remember good, headless mode was assigned to channel 9.

found it
I'll test it asap ^^.
Have to say i like this forum . Everyone is very helpful and nice it seems ^^.

*edit*
tested it on my jjrc 1000, and it's working.

Here is my config (for a 7e with 2x3 switches added)
FMODE switch controls the headless mode
The 2x3 switch next to it controls the rate (40%, 65% and 100%)
HOLD switch enables the flip mode (only works with 100% rate as you flip by fully steering into a certain direction)
The 2x3 switch next to it controls the lights (off/on/blinking)

For those wanting to make their own config:
channel 5 = lights (-100 = off, +100 = on, in between is how fast the lights flash)
channel 6 = flip mode
channel 9 = headless mode

So I'm really enjoying your config, but when I move my stick forward, it goes in the direction of the blue lights which is actually the rear. So if i just pretend like the blue lights are the front it would work fine, but I just don't like the battery cables toward the front of the quad, is there anyway to make the red lights be the front and blue lights be the rear?

All you need to do is reverse the Elevator and Aileron channels in the tx ..

Worked like a charm. Thanks!
