I assume that you have a correct dimensioned volt divider for 4S which brings 0-16,8V to 0-5V, if so in config.h change "#define HOTTV4_VBATLEVEL_3S VBATLEVEL2_3S" to something like "#define HOTTV4_VBATLEVEL_3S 129" if you want to be notified when current voltage gets below 12,9V...

Ok, now I see what you mean. Should be possible, because the Mikrokopter voice files are officially available from Graupner and I think it should be possible to get such a behavior as shown in the video. Not planned yet to implement it, there is a little time left next week were I could take a look...

As described on the GitHub Page - currently transmitted data are: LiPo voltage, relative height over ground, and flight time since copter has been armed.
Cycle time increases up to 35ms each time telemetry data are getting updated, that why the data are updated with 0.5Hz.

Any Plans about Voice Output ? somethink like that : m Voice Output is made by the transmitter, e.g. MX-12, and not by the receiver. If you have a working telemetry, just enable voice output on your MX-{12,16,20} and select the values you wanna hear and put the voice output on a trigger. E.g. I hav...

OK, I'll try to describe it better (don't hesitate to ask again, if it won't work. I will also update the github page in a couple of days). First thing, I don't have any idea how to connect a LLC because I don't use one. I just recommend to use one, so I don't want that someones Copter goes down due...

I don't own a MC-32, but the website says:"Integrated Graupner HoTT 2.4 GHz transmission system", so it should be capable of handling HoTTv4 data telegrams. And yes, RX/TX together, because HoTT uses one wire to transmit and receive data (the extension handles this and shuts down RX when d...

Finished implementation of PID value adjustments via Graupner HoTTv4.

I'm not following this road on using a second arduino. As far as I know fred_fr is investigating this. What I can tell you so far is, that the "lag" which happens every 2 seconds when telemetry data are updated doesn't influence QuadCopter stability (from what I can tell, see m). The twich...

Yes it does run on the FC arduino. Currently running on a Mega2560, I hope it bloats the code not to much so it can run on a ProMini too.

Next dev step will include PID reporting and changing

Hi Hamburger,

I'm going to change it immediately to GPLv3, it was absolutely my mistake for being not accurately enough.

Thank for pointing it out.

Current development of HoTTv4 in MW2.0 can be found here: http://github.com/obayer/MultiWii-HoTT

I had the chance to test it yesterday with the solution Alex described, nothing changed so far. I reflashed the Mega2560 board with the original MW2.0 and my telemetry extension and it worked without any problem, so I think that it's not a MW2.0 problem, maybe one of my cables is the problem. I will...

Thanks Alex, will try it this weekend and will let how know how it works.

Hello, today after switching to MultiWii 2.0 I discovered that VBAT readings are not correct anymore, or rather not correct after some flight time. I'm getting the VBAT reported via telemetry and when I start, VBAT says 12,6V which is totally correct after flying around for a couple of minutes it st...

@chriszero Yes and No, what I determined is, that the HOTT receiver is very generous regarding the delays. The range gets from 650us up to 4ms between each byte. Furthermore do I not use a LLC, just a diode between RX and TX, that's all (maybe I should consider using one). Although I'm spending 3500...

Timing issues also applies to the Mega2560 boards, because you still have to wait between each byte that is being transmitted. The advantage of the Mega2560 board is that you don't have to share your serial interface that is used for parameter programming. HOTT telemetry uses only one wire to transm...

Is there any reason, why SIGNAL is used in Serial.ino to define interrupt routines? As far as I know, SIGNAL is deprecated and should not be used any longer, but ISR.
Futhermore SERIAL_COM_SPEED is not used in any SerialOpen() state and therefore has no influence.

I'm having a working HoTT implementation in my own 1.9 version of the MultiWii Software. It is currently able to send you the LiPo voltage and relative height from ground. It uses the same Arduino that is used for FlightControl to generate telemetry data on serial out. The only problem is, that the ...

Would it be possible to fix this bug within the next release?
I would also move the GYRO_ORIENTATION macro into Gyro_common, because it affects all Gyro sensors and you follow the rules of "Don't repeat yourself".
