Hi guys, I fitted the diode in the small green PCB of my 9xtreme radio years ago, but I wonder if, for a radio with no 9xtreme, the diode needs to be fitted on the same place. Yes? no? Maybe?

Thanks, lol.

1. Tick the box beside "PG2 as input"
2. Change the setting by the "AIL Switch" to be PG2.

Mike

That was it! Thanks! I am very happy I got it working.

Hi, I took some pics. I also added the diode for reverse polarity protection.

Yes to the pins, and yes to just the third switch leg to those pins. Mike Hi Mike, I managed to solder to the processor pins! Pfew! I think it looks ok, but the first 3 pos switch I am testing is not working. First of all I am working in the AIL switch, which goes to pin 43. I tried with all option...

Well, the radio just arrived. I fitted the blue screen and flashed 9x. I tried with the 128 version and surprisingly seemed to work well! Maybe turnigy is fitting the 128 processor again? I am decided to try to solder the main processor for adding two switches. I attached one pic. are the ports I ma...

To connect to the processor pins I use a small piece of stripboard glued to the main board. I then wire to the processor using single strand "kynar" wire, then use normal, stranded wire to the switch. A picture of this is on this post: https://openrcforums.com/forum/viewtopic.php?f=5&...

If this is a completely unmodified 9X, the there are 3 "spare" processor inputs available, so you should be able to change 3 switches. The spare inputs are: PC0 Pin 35 PB7 Pin 17 PG2 Pin 43 It should be a case of swapping a switch, connecting the existing ground and signal connections (gr...

Hi guys, I have to modify a 9x radio for a friend, and I wonder if it is possible to replace 2 position switches with the 3 position ones to the plain 9x, and how to do it. Of course it will have er9x flashed. The more 3 pos switches the better, but two should do the job. My first idea is to replace...

Mike

Thank you very much, Mike. I just flashed it, I will update you if I have that error again.

As always, thanks for everything.

MikeB wrote: ↑Tue May 05, 2020 9:36 am I assume you only get this error at power up?
I'll look at the code, this encoder is sharing the signals that connect to the EEPROM, so there is a possibility I have something not quite right at start up.

Mike

Hi Mike, yes, I have seen the error only when powering the radio on.

Hi, I think this will be a thread for Mike. After installing the encoder via the arduino and that port in the 9xtreme, from time to time, and I think with no reason, I get the bad eeprom error, so things are erased from my radio. Thanks to you, guys, I discovered it is possible to create copies of m...

In my opinion you won't need gyros, you need someone to teach you how to fly. You do it alone, with or without gyros, you will crash it at best, or injure someone, yourself, or damage some property at worse. Get an RC simulator for your computer. But the most important is as I mentioned above, find...

Hi guys, mi wife told me I am getting my first rc plane for my birthday and I am super afraid of crashing it. I have read a lot about gyros and definitelly I am going to need one. I have seen 2in1 gyro and receiver: https://www.aliexpress.com/item/4000178317639.html?spm=a2g0o.cart.0.0.4fc83c00bbsxDS...

Yes, always backup your radio's eeprom regularly.. Basically every time you change something. You can backup the eeprom to the computer (recommended), and also to the SD Card. As you might also know, you can backup models to the card or computer. João Will do! Both, no doubt of it. Some of the mode...

Well, at least you tried, thank you very much for all the effort.

I will setup the radio and then I will create eeprom copies, no prob. Live and learn!

At the other hand, this is how my radio is looking at this very moment. It might not be super clean, but there is not a lot I can do with so many wires.

Anyway I am very happy with the end result

Hi, I just attached the file here.
When connecting the radio to the computer, I have seen not all of the models are gone.

Anyway, the most importan question is: Why that eeprom error?

Small downside, it seems somehow all the models, config and everything in the radio is gone. There was an eeprom error...

But no probs, I will take it as a way of super clean instalation and I will start from the very beginning again.
But i will make safe copies, lol.

You have the encoder connected to the analog inputs (A2, A3 and A4), not the digital inputs (2, 3 and 4) that are down the opposite edge of the board. The display shows correct communication. Mike Correct! I soldered them right and it WORKS!!! THANK YOU Mike and Joao for all the help along the year...

Hi, I just flashed the new erskytx version, and I took a pic of the debug mode, and also of my arduino. Maybe you can see something wrong.

Hi, I will check that as soon as I arrive home. I dont have very good pics of it, but I took two in the process, when I was sweating blood ff000ca0-33b5-4416-a202-37cfff694fe0.jpg 33dbe79d-3fe3-45fc-beb2-213b288ba955.jpg I will try to take better pics later on. Basically what I did was, first to sna...

I also checked the arduino is correctly plugged in the 9xtreme (it has also light) and I checked the arduino button is not pressed. Hope it helps.

Hi, this is what I have.

In the diag menu, ENC is always 0

I also noticed when I press it up and down it makes a "beep" but it does not do it when left and right

Mike

Hi Mike,

Yes, I have flashed it. So far the arrows work, but the rotary and the central button dont. Not sure if I have to activate something.

Hi guys, I think I did it! Or at least part of it! I managed to install the encoder, and the 4 arrows are working great! But the rotation andthe button do nothing. I guess I have to do something in the hardware menu, right?

I am super excited, close to finishing the radio!

For the encoder, the switch goes to IO4 and the two encoder signals go to IO2 and IO3. If the encoder "goes the wrong way", swap these last to signals over. The encoder and its switch also need a ground connection. I'll post a test version of erskyTx on the test versions thread, first pos...

Ah OK just one, I thought I had to join all the yellow circles.

So those are awesome news, just 5 wires!!

Hi Joao, thanks for the reply! Great to know I have it flashed propperly, and that I have to throw less wires :) I already soldered the encoder to the small board. I think I have clear what to solder in the red circles. But the yellow circle where does it go? I attached a pic. Thanks! encoder order....

Well, meanwhile the arduino chip took short time to arrive, the connector is still not here... But that gave me plenty of time to read in the forum about the encoder, and I think I am going to approach it in another way. Instead of fitting something between the encoder and the PCB, I am going to sha...
