How to connect AUX2 from the RX

[rihardsb]

Hello,

I've HK 6ch TX/RX and Pro Mini. How do I connect AUX2 from the RX ch6, since only mode (AUX1 ch5 on the receiver) is currently connected to PIN7? From the firmware code it says that AUX2 is also on PIN7 but not used! Do I have to modify the code in the current development version of MultiWii?

FYI finally today I got my quad flying and I'm very happy with the acievement:))

Best Regards,
Rihards

Any chance you can use the PPM Sum method? It works well and you can reduce six R/C Rx cables into just one cable.

It's not possible to use more than 5 RC channels on a 328p atmel board, except if you use a serial PPM receiver.
(in fact, it is, but it's not coded in multiwii )

Thanks guys for the answers! So I guess I might do some coding to change one of the unused digital channels on Arduino Pro Mini as an input for ch6, or else maybe purchase a different receiver in the future.

You can hack the reciver and pull the ppm from it.

any change since v1,8 about this as i'm seeing there are no triple switches in the gui since v1,8

I would love to use aux 2 (and may b even the 2 servo channels) on my arduino mini.

is this possible now or is this a hardware/software issue still ?

edit : I use a aurora 9 with a 9ch reciever

V1.8 does not change anything. There is no code in this release for the additional Aux channel on your Pro Mini. As mentioned, the PPM Sum method is available to solve the problem.

Is it the only way to use more channels on the pro mini or are there other way's? ppm is just not going to work for my optima 9

Do it the Hardware way

A Harware PPM encoder.
