A forum user is making a few 9xtreme boards..

Yep, CPU dead, I have one of those radios from a friend here at home with the same problem. Will attempt to replace the CPU as well, when I have some spare time

João

Mike, can't it be done using a GVAR?

João

I have just seen your post. Sorry. I have an AR9x radio with a multi Module inside....
Also have a 9x radio with a 9xtreme board with a Multi module installed inside.

João

Yes, I have an AR9x radio currently in working order.. But it has a Frsky DHT module inside, not a MUltiProtocol module.
My other AR9x radio that has a Multi module, broke the little battery connector. Need to fix that

João

Nice that you found it.. Well done

João

So, the last example worked for you? did you try it?

João

The answer to your question is, there is probably a simple way, but we need more information please.. What exactly do you want to do?

Simple is relative by the way What is simple for me might not be for you

João

The loss of control is probably caused by the RF module. You'd probably better buying a better one. Try Frsky. A bit more expensive but much more reliable.
Yes, you can (and should) update the radio's firmware, but I think it won't fix that problem. as I said, the problem might be the module.

Hello, im not sure if this is normal in erskyTx but on OpenTx this is not happen. When i turn off Tx and turn it on back, ten throttle is pushed for about half second, it is very scary with mounted props. My radio is 9XR Pro with erskyTx 222 EDIT: when i disable (uncheck) Fix Offset in Mixer then t...

My concern was whether the charging function would still work with the MOSFET in that position. Yes, it will because it will polarize the Mosfet normally with the positive entering the source, but it will blow if the charger is reversed, that is why i suggested a protection on the charging circuit....

Hang on, I'm not sure the diagram from João is correct. The gate is OK, but I would put the drain to the right of the existing cut (to the switch) and the source to the track leading the the connector (pin 3). Mike Mike, I think the connections I posted are correct.. The Mosfet should be a P-Channe...

As far as I understand it, I would do it like this on an original Turnigy 9x board without upgrade boards.
Mike, does this look right?

Thanks

João

EDIT: And perhaps I would put another one on the Charging circuit too.

I would think about that carefully For example, what features are currently limited due to RAM compared to the other processors?

João

Mike, isn't that bad for the m64?

João

Mike, what about using Eepe / Eepskye and an FTDI to flash it?

João

The Arduvoice connects to other pins of the processor. The pins where the left vertical stick's trims are connected originally.
These are then moved to the ArduVoice board.

João

Nice, thanks Mike.. I guess I will have to update my Multi Modules? I haven't done it since a few months now..
By the way I do apologize I still didn't do that testing on my 9XT. Will do in the next days..

This version also has initial support for displaying the results of the multi-protocol module spectrum scan.

Mike

Will this be implemented on the other "older" radios as well??

Thanks.

The SKY board processor has 256K of flash memory, the AR9X has 512K, which is why you need the ersky9xs_rom file (s for small).

Mike

Please read what Mike said here You are probably flashing the wrong file.

João

I think the reason they state it shouldn't be used with an IC engine could be electromagnetic interference?

João

It has been a while, so I am not 100% sure, but you "might" be able to modify 1 of the switches... But might also deep nd on which processor the radio has. I have it done on my 9x radio, changed the ELE switch to 3 position, and also placed 2 push buttons on the back. These two are connected to the ...

Understood, thank you

João

If you are using FrSky hub telemetry, then rebooting the radio, with the Rx still operating, is likely to end up overflowing the telemetry buffer in the Rx and or Tx module resulting in corrupt telemetry data until the radio catches up and the buffers get flushed. Ok, that is one out of the equatio...

Mike, there is some kind of problem with the latest ErskyTX, at least with the 9XTradio. Some models need the SBUS signal of the trainer RX to be inverted, and some not inverted. So, something ,might still not be quite rightk, at least on the 9XT? Also today I saw some odd behavior. I have learnt th...

I also have Linux on my computers, and I love it for my music work. I use Ubuntu Studio.
But I have dual boot, so I can select the operating system at power on.

João

I never used it in a virtual machine.. But it works well on my windows 7 PC.

João

Have just downloaded it, installed on a windows7 PC and it works..
Perhaps you should just download it and install it again.. Remove the old one first.
João

Been a while since I last used it but I would think so..

João

Na minha opinião sim, e além disso a equipa do OpenTX já não suporta este rádio. Er9x suporta e de vez em quando ainda há updates para ele.

In my opinion yes, and also this radio isn't supported by OpenTX anymore. Er9x does support it, and quite often Mike releases updates for it.
