You were lucky. That little thin wire could have killed your processor. It wouldn't be the first, nor the last one

João

You probably need to slow the programming clock down, this is done by adding -B 10 to the AVRDUDE command. In eepe, go to the Burn|Configure menu and put -B 10 in the extra arguments field. Also, I recommend going in to the Burn menu and selecting "Set Fuses to Protect EEPROM", otherwise the the EE...

I have one here from a friend that failed in a similar way as yours. it was powered by a 2S battery.
Not a very good design I guess

João

Yes, the m2561 and Er9x is the way to go. It even supports the MultiProtocol module. and as it seems you are comfortable with electronics, you could even build a voice module for the radio. Er9x even supports adding a couple more switches and/or changing a 2 position switch to 3 position. It is very...

Another one bites the dust. These radios seem to be really bad.

Oh so it's better to switch Vcc and PPM than Vcc and GND ?

Yes, switch VCC and PPM.

You can only flash the 9x radio with that code if the radio's processor IS an Atmega128. If it has an Atmega64, it will not work as it has half of the memory.
No idea about the eeprom error. Is that during the flashing process? Strange.

João

well, it looks a bit better than the other antennas, right? But were you having that low RSSI that close to the plane??? I don't really like the placement of your horizontal antenna. It looks like it is quite close and parallel to the power cables? I think you might have to repeat that test at your ...

Mike, thank you so much. I can see we are approaching Xmas
Is the Logical switches delay in the logical switch setting already or still at the bottom of the screen?
The new functions will allow us to simplify some of the models I suppose.

Thanks

João

Beacause as far as I know, OpenTX never saved models.. Only the completely eeprom..
That could have changed recently of course, and I don't know.

João

I try to backup most of my data in more than just 1 drive.. And even store them separately.

João

Those are dipole antennas, They should be much better than the original antennas, if they are well made of course.
I use only dipoles on the DIY receivers I build..

João

Yes, that is a safety feature..
Well done fixing the problem

João

Antennas inside the fuselage?
Any carbon parts around them?

João

What is RNT?
Picture of the pad please?

João

Please post a good picture of the trainer menu on the teacher radio.
Also, the student (Trainee) radio should not have the same model as the trainer radio. It should have just a default model with the main 4 mixes..

João

Thanks Mike. that is wonderful.. Does that mean Eepskye doesn't need eepe installed to run anymore?

João

Thanks for all Steven. I wish all the luck. Hopefully we will see you again soon with some other cool projects.

João

Mike, what about the possibility of adding an External Eeprom module? I use a few on some of my projects, but they are i2c.
I believe there are also SPI Eeprom chips.. They shouldn't need many components also. Quite easy to connect, I would say.

My main radio is that 9xtreme you already know, this one has little use, so I am surprised it failed so fast.

Sometimes that is the reason things fail faster

João

Did you find a direct replacement?

João

If you follow one of the links under all my posts, you will be able to donate to Mike.
The other link points to some Er9x / ErskyTX tutorial videos I have made a few years ago.

João

It could be a broken or disconnected Antenna on the MPM.

João

I remember doing something similar a few years ago, but on Er9x, not OpenTX. As far as I remember, I would hit a switch, then had to launch the model right after, then a couple seconds later the motor would turn ON, to the throttle position setting, not necessarily to full throttle.

João

As far as I know, all 9XR-PRO radios have a bootloader Even my pre-production radio

João

But DO NOT insert or remove the module while the radio is ON. That could damage it.

João

Mike, you could still use it to adjust a global variable, if you use it combined with a key to change screens..

João

EDIT: Hmmm, wait, I forgot that some of use do remove the navigational keys.

Are you using companion to flash Er9x?
I think you should use Eepe instead. Get it here:

www.er9x.com

João

That would be cool Mike, thank you.

João

The cheap encoder I installed on my 9XR-PRO didn't work very well until I did this:
