Oh, I used com 3.

Actually I read both and they are almost identical. I had already taken the button off and cut the trace on the opposite side before I saw your post that it is not necessary. Oh well, practice makes perfect! I just soldered to pin 34 of the BT module. Also I removed the pins and direct soldered to t...

jhsa, That did the trick. Neither radio reboots after 10 min! I used the version labeled for the multi. I misunderstood what each version is for. So all is good. My two extra 3 position switches are the "extra" switches from the main board. The P3 3 position is from last years mod to conve...

Thanks jhsa. Should I use the latest by date (for multi) or the latest Bt (fix for com2)?

jhsa, did you experience a quick reboot (with drop in voltage) when connected via bluetooth? I have two 9xtremes with your bluetooth mod and have succesfully connected and controlled the Master. The slave is a new 9x with just the 9xtreme added. The Master is a previous 9x with a new mother board (1...

Would a RMILEC signal converter (up to 18ch) work as well?
I have used it with one XJT and one X receiver for 12 channels.

Thankyou jhsa! Beautiful photos and very clear and concise annotations. This is like a "wiki" installation guide.

Ok, after alot of trial and error I have been able to map the "EXT" with the 9 pin connectors:

EXT1 A5
EXT2 A6
EXT3 B7
EXT4 B9
EXT5 A9
EXT6 B5? does not work
EXT7 A7
EXT8 B6? does not work

So we now have available six more 3 position switches!
Thankyou Mike and Steven

So, I now have 2 9Xtreme boards up and running well. Very easy to install compared to all the mods to original 9x (megasound, replacing pot with 3 position switch, joystick for gimbal control and later a headtracker). Now I would like to replace one or more of the 2 position switches with 3 position...

Thankyou,
I should have known that.

Hello, I received the 9xTreme boards yesterday in great shape via China postal/US postal. Today the installation went well and the Tx comes on with speech. I have tried to read the Tx eeprom and firmware but get an error message that "Tx disk not mounted". I have not seen anyone report thi...

I have in use two of RMILEC converters. It converts signals both ways if needed in a different application. It will convert up to 18 sbus ch. to pwm or ppm. I use one with XJT/X8R combination. I found one here on ebay: http://www.ebay.com/itm/like/311395264338?ul_noapp=true&ul_ref=http%253A%252F...

The original board has a '64A on it. In passing, the '128 takes twice as much current as the '64A or '128A (40mA instead of 20mA).

Mike.

They are Atmel GA128A, 1107.

They indeed do have an Atmega 128. Just received two of them. I am going to replace them both with the Atmega 2561.

MikeB,
There may be more '2561s out there than you think. I have four 9x tx with '2561. I like many others are mostly silent in the forums as I have mediocre technical abilities.
Thankyou,

Thanks Mike. I will try the test version when I get back to the computer.

Maybe I am missing something. Is there a way to save the voice alarms with EEPE . I seem to lose all of them when I edit a model on the computer and transfer the model back to 9x. This 9x has 2561, megasound and FRSKY mods. Er9x is FrSky mod version.

Absolutely proffessional! Thank you Jhsa, Nigel and Mike.

Try studying this series of tutorials. Long but excellent. After viewing these I actually understood the er9x style of programming.

Been flying two FrSky modules at same time with no glitches and good telemetry.

Where in Canada are you? I could help you if you don't mind shipping to Michigan. Or if you are near Windsor or Sarnia you could bring it to me, fly some, and fix it together.

Thankyou

Not quite sure why I can not open your eepe file. eepe (rev 392) sees it as "hex" and wont open it. What am I doing wrong?

1+ for the continued development of the 9x. With the 128 or 2561 they are far from obsolete. Thank you for the continued efforts!

Bob,
You might have try using the command prompt in Windows. I used this command with success:
C:\Program Files\eePe>avrdude.exe -P USB -c usbasp -p m2561 -B 500 -u -U lfuse:w:0xDE:m -U hfuse:w:0xD1:m -U efuse:w:0xFC:m -v

Your path may be different.

1+ thank you for the 2561 version as I am running 4 9x transmitters.

The atmega2561 works just fine in all four of my 9x radios. If you haven't purchased the 128 then it seems to make sense to use the 2561.
I purchased these at Digikey: http://www.digikey.com/product-detail/e ... -ND/735457

Is this a good price and place to order the atmega2561 ? (http://components.arrow.com/part/detail/41667964S7386796N3744?region=na&utm_source=octopart&utm_medium=buynow&utm_campaign=octopart) Atmel - ATMEGA2561-16AU: (http://download.siliconexpert.com/pdfs/2010/11/7/1/41/43/117/atm_/manu...

If you are not capable of this fine soldering, I live near Holly Mi and can repair this for you.

If you search for "windows 8" you will find references to how to get around installing unsigned drivers in Windows 8.
