2600 Ohms

How bad is it???

Edit: Just measured another pot: 490 to 2440 Ohms, and 2740 Ohms total.

Sure. The resistance is about 580 to 2430 Ohms, end to end.

Can someone please share the value for the pot with an amplifier?

For those who consider upgrading to Taranis sticks: there seem to be a version of sticks without amplifiers. Not sure if it's a 'first batch', or a 'modified' one... Here's the photo (sorry for the quality - I had to use a phone): http://www.amg-rc.ru/off-topic/taranis_no_amplifier.jpg I got this st...

Mike, is this a feature for non-stock sticks? Like those from Taranis on a stock 9x board?

Ah, I see now... Sorry!

I'll send you a PM regarding the boards... Thanks!

Using the Iksbob's files, I've ordered 10 PCB at this Chinese maker , they cost me $9.90 plus $3.90 for shipping to France. They even send me two more free PCB, because the project is open-source ! Here are the results: http://jpparisy.free.fr/schemas_bateaux/rotary_encoder-4.jpg Am I the only one ...

mmilan, welcome to the 2561 club!
I'm glad everything worked well for you!

1. When the Smartieparts board is not programming, its outputs should go to three-state. If they didn't you wouldn't be able to use the MENU button as that shares the SCK line, or the THR and AIL switches as they share the MISO and MOSI lines. Menu button works just great, as well as the THR and AI...

Hi All, This is not directly related to Smartieparts board (although it is one of the components in this equation), so I thought I would rather post it here. I have a pre-pre-beta of the Smartieparts programmer installed in my 9x. It's the version that was a couple of versions before 2.1, and it's n...

Mike, that's an extremely valuable piece of information! Thanks a lot!!! I believe it needs to go into Wiki, so that people could find it. I translated this text into Russian, and will share if there are still concerns (for me it looks clear now, but there are much more experienced people on the Rus...

Mike, just one more note regarding eepe: when I load an eeprom from my new 2561, eepe calls it '(M128)' in the window title. Is it because M128 and 2561 have the same EEPROM size (4K)?

mmilan, soldering is the most tricky part. The rest is easier, thanks to this great community!
Good luck!

All, I suspect this has been discussed already, but I'd like to ask once again. There's an issue being discussed at another forum (it's Russian-speaking, so I won't post a link), and I think this is quite important. It's all about Trims that seem to affect Limits. The example is quite simple: let's ...

True!

Thanks a lot!!!

No, no, it seem to be a bug with 2561 in eepe. I just rechecked: I set the version to er9x-128-frsky and the chip to M128. Clicking 'download' gets me the 'er9x-128.hex' (no even need to save the changes). But when Version to Download = er9x-2561, eepe downloads just the er9x.hex (no matter what Pro...

Oooops! I think it's a bug in eepe. In fact, I downloaded new firmware via eepe. In eepe's Preferences I just set: Version to download: er9x-2561 Processor: M2561 Then, clicking "Download" button got me the latest er9x.hex file. I just realized that the file may still be wrong. So I went t...

That was the first thing I rechecked... The fuses are DE / D1 / FC (here's the recent output): C:\Program Files\eePe>avrdude.exe -c usbasp -p m2561 -U lfuse:r:-:i -U hfuse:r:-:i -U efuse:r:-:i -v avrdude.exe: Version 5.10, compiled on Jan 19 2010 at 10:45:23 Copyright (c) 2000-2005 Brian Dean, http:...

Maybe this is a coincidence, but I read in another thread someone had a similar "signature mismatch" when sticks were not idle while flashing. So beofre I saw Mike's suggestion, I put the radio back together, and it flashed successfully: ====================================================...

This looks wrong...
The chip is 2561. At least that is written on the chip itself.

Use UPPER case "B", "b" is a different parameter! You're da man! :) C:\Program Files\eePe>avrdude.exe -c usbasp -p m2561 -B 500 -u -U lfuse:w:0xDE:m -U hfuse:w:0xD1:m -U efuse:w:0xFC:m -v avrdude.exe: Version 5.10, compiled on Jan 19 2010 at 10:45:23 Copyright (c) 2000-2005 Bria...

Oh, that was a wrong paste above... But there's no difference with either -b 100 or 500. Perhaps, a verbose output gives some more info: C:\Program Files\eePe>avrdude.exe -c usbasp -p m2561 -b 500 -u -U lfuse:w:0xDE:m -U hfuse:w:0xD1:m -U efuse:w:0xFC:m -v avrdude.exe: Version 5.10, compiled on Jan ...

Thanks! So it's not the fuse settings...

Mine does supply power to the mainboard - I remember the radio powered on by itself when I connected the USB cable.

Great, thanks a lot! Meanwhile I connected the USBasp (I use Smartieparts board) and tried to read the firmware to see if the new 2561 is soldered properly. But avrdude gives the following error: ================================================================================= Started AVRDUDE C:/Pro...

Dear Mike & other 2561 owners, I just upgraded my ATmega64 to 2561. Now I'm trying to understand the flashing sequence. Do I get it right that I need to set the fuses first, and then to flash the firmware? What are the proper fuses for 2561? Also, in the latest eepe (revision 391) I see er9x-256...

Understood. Thanks a lot!

Thanks a lot, Mike! Then I will consider moving to 2561 (need to improve my soldering skills for that - will practice on the voice board).

BTW, do we need an inversion circuit between S.PORT and MISO at all, or can the inversion be done in SW (just a thought...)?

The unidirectional connection is simpler, and there is currently no functionality to be gained by implementing a bidirectional one... Well, if there's no foreseeable use - then of course it makes no sense to add a level of complexity. Actually, the SPort interface is HALF duplex. It is a single wir...

Hi All, FrSky site says S.PORT is a full duplex interface . But if I get this thread right, Mike suggests to connect it to the 9x board so that the 9x only receives data from S.PORT. Is this correct? Does it make sense to make a "full duplex" interface between 9x and S.PORT on XJT - perhap...

I'd like to remind everyone that every connector in the path subtracts from the 60 MW output. It's not like 72 or other frequencies where we started with 3/4 to 1 watt of output power. There is a point where the output power is reduced a lot. Hi All, I'm a 9x user for quite some time now and recent...
