(I've turned the backlight on before displaying the "Hardware Menu Enabled" message so it is easier to see).

This is a good idea in general Mike, perhaps you could leave it in?

Thanks

João

You open your radio and disconnect the ribbon without removing the battery, and your radio will probably be toast.. This is not a mod, this is about alerting people to the fact that they can destroy their ORIGINAL, UNMODDED radio while doing normal maintenance.. :o We have seen a few processors dest...

Nice that it worked, although the internal module sould have nothing to do with the problem.
Maybe you had another wrong setting somewhere as you say..

João

They should have asked Mike.. He knows how to, and Ersky9x has it for ages.

João

Yes it does.. The m64 is very limited in space and RAM. The m2561 has the double of the Flash memory, the eeprom, and also the double of the RAM.
The m2561 is supported by Er9x.

João

I fully understand you

João

Ok, so they didn't really die

João

What happened to the other radios then?

If the wires for the other two LEDs are disconnected, then those two signals on the connector are available as extra analog inputs, which seems more useful to me!

Mike

Definitely

João

All Ersky9x radios support scripts.. Not LUA though, which is not bad at all.. Mike developed another script language for Ersky9x that is lighter and runs on all platforms
Ok, maybe not so many available.....yet!!

After Taranis Q X7 entered the market with the price of 115$ investing any more money to 9X looks pretty weired to me. You know, having held Both Taranis flavors and Horus in my hands and played with them, I still prefer my 9x radios with upgrade boards.. and by using Ersky9x I have many more possi...

I still think someone would have to order it, assemble it, and sell it. I can solder that chip, but I don't think that people without some experience will be able to do it without damaging the chip or the board. Also, it would be very difficult to get a group of people together to build this, especi...

Ok, but you don't see normal users soldering the 100 pin processors, right? ;) Unless someone produces this, I don't see it being viable.. But of course, the files are there, if you can build it, it is already possible. You might be the only one though.. And add all the prices you just posted above....

Yes, you can send the 9XT board to be made, buy the components, and build it yourself. I believe Steven released all the needed files to the public. But it would be very expensive I think.. there were a few boards in the past. Skyboard, Ar9x board, ArUni board, 9xtreme board. I think all schematics ...

I've considered before whether using a second processor could help with the 9X, but I've never found a way to split the functions between two processors to reduce the flash/RAM requirements on the AVR processor. Mike That would be more or less what the 9XT is doing? The difference is that it does a...

I believe the 0.5A regulator is more than enough.. the radio shouldn't take even 100mA :) Be careful with the pinout of the new regulator. If it was me I would try to find a low dropout regulator. I attached the datasheet for the L4940.. L4940_LDO_Regulator.pdf This could also be useful to you.. it ...

No it doesn't have a DAC. It does, however, have timers that may run at up to 72MHz. These are able to provide PWM output (driven by DMA), so better audio with fewer filter components needed. Nice :) I'm not sure whether any work could be offloaded from the main processor. To add another RF module ...

Mike, I do think that this chip has a DAC? Would this make it easier? I mean, less components? Better audio quality? It certainly has many pins for other features. For example, would it be able to use this.board to generate signal for another RF module? If so, would it be reliable? Perhaps one of th...

Got a link to those boards? Mike this is what I have. https://www.ebay.com/itm/STM32F103C8T6-ARM-STM32-Minimum-System-Development-Board-Module-For-Arduino-/311156408508 Probably not the same seller though. but they are very cheap. Perhaps this can help as well.. http://grauonline.de/wordpress/?page...

Yep, pad is on the wrong pin This explains the second problem "target doesn't answer".. You will probably need to solder a wire between the resistor connecting to the correct pin, and the smartieparts board.

About the regulator and cap, try Ebay or aliexpress..

João

Mike, as unfortunately there aren't any upgrade boards for the 9x radios, would you see any gain in using one of those Arduino compatible boards with STM32f103C8T6 as voice modules? It has more pins available than the traditional arduino based on the AVR chip. That could probably be beneficial? I am...

I don't know what docs you are following to flash the board, but have a look at these files. I think you might be missing the last step, which is what Mike has been trying to say..

João

That is the question, can the trainer port do serial??
Thw Devo radios have other hardware I think?

João

Remember, this mod wouldn't be only for you. :) There are others that might want it and still use the trainer port. So WE have to speak PLURAL here ;) I am not sure the trainer port being able to do serial. I remember asking Mike about using it for connecting another module once. I am not sure that....

The way serial communication works between the ArduVoice (arduino based) module and the radio implies that we do remove the left vertical trim switches from the main processor, and connect them to the voice module to be controlled by it. This frees the processor pins to control the voice module. The...

Ok, progress.. this error tells me that the USBASP is recognized, but the radio doesn't. probably because of that SCK pad being in the wrong place. We will need a good picture from your radio's mainboard. we need to see to which pin that SCK pad is connected to :o One other thing. NEVER, BUT NEVER u...

Good idea.. Please get the drivers from the smartieparts website..

João

I don't have windows 10, and I don't want to have it so I don't know how to install drivers on it. Apparently, it seems to be an headache. Unfortunately I don't know how to help you with that

João

No, that would be another problem.. :( perhaps you have a so called V1 9x mainboard that has the SCK pad on the wrong pin?? if that is the case then you will have to do some soldering. Did you try to power the radio ON while trying to read the firmware? if not, please try and see if that error goes ...
