Hi Barry,

try different values for "freq"
I have two 4in1 modules here which need -85 (yes indeed negative) as value.

Klaus

BTW: did you update your 4in1? The firmware with which banggood ships the modules is rather old!

I tried the usual suspects without luck.
But Farnell Germany directed me to their sales partner hbe-shop.de
where I could place an order.

Klaus

... so all the hardware you need is the USB cable to be able to flash it. To get the firmware on it, it is probably easiest to install "DFUSE" from STM. I have a suitable .dfu file to use with that to get you back running ... That sounds great. Now the only problem is to find a dealer who...

OK then,

next steps:

1. read STMs contents
2. desolder STM
3. solder new STM
4. flash new STM

right?

Can the STM be flashed with USBASP or do I need s.th. different?

Klaus

Hi Mike,

I crossed the whole cable.

i.e:

PC <-> 9XT
-------------
5V <-> GND
D+ <-> D-
D- <-> D+
GND <-> 5V

Hello guys, these days I had to learn that it's not a good idea to tinker with electronics too late at night ... :( Unfortunately I cross linked the USB to my PC. Now the 9Xtreme works as it should except USB connection. When plugged to a PC there's no reaction at all (as well PC as 9XT). No visible...

... and using the bind option in the menu ... Yes, and I have the latest test version on both radios and tried both AUTO and manual selection. The displayed info on bottom of binding page corresponds to the then automatically selected mode on protocol screen. When I select DSMX-22 on the PRO while ...

Now that my telemetry problem is solved I stumbled over a puzzling issue: I have an OrangeRX RX3SM. The PRO with a Banggood 4in1 recognizes it as DSMX-22 / 6ch. But with same 4in1 in a 9XT it is recognized as DSM2-22 / 6ch. If I disable telemetry, the 9XT works only in DSM2-22 mode. But PRO (with sa...

HEUREKA :D 8-) :lol: It works! Because of some false assumptions while error tracking I connected the telemetry output of the 4in1 to COM2 (pin 14) of my 9XT. Now the telemetry out of the 4in1 is directly connected to COM1 (black cable), 4in1 is set to inverted telemetry out (this was the trigger fo...

Hi João,

the naming is a different thing...

My "problem" is the fact that I can't select COM2 for protocol DSMx.
So with 9XT, Bangood 4in1 and a DSM RX I can't use the AUTO function for binding
(or I find a way to connect the 3.3V level telemetry output of the 4in1 to COM1).

Klaus

Hi MIke,

I found that when DSMx is selected for telemetry UsrProto
only COM1 can be selected as FrSky Com Port (PRO and 9XT).
Is this as intended?

Klaus

Hi guys,

I checked the new menu on two 9XR-PROs and three 9Xtremes and all works well.
Very nice

And a Happy New Year to you all

Quite a few different processors out there...
Last summer I got a spare motherboard from HK for the 9X that is marked with

ATMEGA128A-AU
Green
ED040502-H16D
1104
110404

but with ATMEL-Logo on it.

Yesterday I found that arduino IDE (1.6.10) only works with WinUSB drivers provided by Zadig (2.2).
But avrdude provided with eepe (er9x) doesn't work with this driver.

On the other hand avrdude (eepe) works with libusbk and libusb-win32, but arduino IDE doesn't.

Klaus

Maybe this or this can help.

Klaus

Fortunately I didn't have to build my own computer
but built (pre-proportional era) remote control stuff like Grundig/Graupner Variophon with my father ...

But back to topic ...

So nothing world-moving for s.o. who grew up with computers in a pre-windows era
( anyone who remembers ZX-81, C64, Amstrad CPC, CP/M, DOS ... ? )

Klaus

Is there any benefit using the installer instead of the portable version?

Klaus

Where did you put the wav-file?
According to e.g. this post you have to put it in a folder named "music".
Your SD Card is formated with 32kb cluster size?

Klaus

A throttle cut switch is indeed a nice feature to prevent injuries caused by accidently hitting the throttle stick, but please always keep in mind that besides all programming aspects there is nothing you can do on TX side that makes your aircraft 100% safe (at...

Found parameters for audacity's "truncate silence" that give results I can live with
Klaus

Hi Klaus, Is this with all of the TTS engines, or only one (Ivona, Google etc)? ivona:...........................delay at start seems to be about 0,10s - delay at end about 0,30s google:.........................delay at start seems to be about 0,05s - delay at end about 0,15s microsoft:...............

OK

then what about "Bye, see you soon" or s.th. like that?

In the meantime I used audacity to cut silence by a batch job but this cuts every little piece of silence.
That also doesn't sound good ...

What about this

Hi folks, first of all a big thumpup and thank to Caffeine for creating this tool. I simply have a problem with numbers (maybe there's a simple solution I just fail to see): Every generated sound file starts with about 0.1 sec of silence. For a single file that's no problem but composite numbers lik...

When going over 100% of output with some receivers or servos you can get into some trouble
(some channels may interfere / some servos may bind) because of exceeding design parameters
(of TX module, RX, Servo,...).

So when you do this, please check whether everything works OK ...

Klaus

Hi Mark, besides weight there are the limits (which are processed after the mixes). No matter what (input * weight) is, the output does not exceed the limits (normally 100%). If you want more than 100% of output you have to enable "extended limits", only then you can set limits beyond 100%...

Hi João,

unfortunately I cannot test, 'cause every 9X in my reach I changed to M2561.

Thinking about the problems with M128 that occured in the past (the analog ground thing...)
I also would deem the M128 as the evildoer.

Changing to M2561 as Bob suggests is not an option?

Klaus

Hi Rick,

I had the same problem some time ago with the 9XR-Pro. Unfortunately it's not that easy.
My solution was a "cross-link". I wired ppm2 to pin 1 of the module bay and connected the spektrum module
to the place where pin 1 was formerly connected.
