Audio (voice) - Stock 9X PCB

[jhsa]

Hello misters!
Help me please. After connection of Audio (voice), LCD doesn't work in a simulator mode (at connection of PHONEPLUG). Management works.

Does the radio work normally with the audio when not connected to the simulator?
Also How do you power the radio when connected to the simulator? From the USB?
Do you have a battery inside the radio? If not, get one and use it

LCD doesn't work at connection of the equipment to the computer through ISP USBASP.
eePe the program works with the equipment well.
I can read and write down memory, firmware, EEPROM...

I disconnected D0, D1, D2, D3 - LCD began to work normally!
I connected - doesn't work.
what can I make?

I have one of those UsbAsp programmers that before had the 200 ohm resistors and when I connect it to my radio, powering it, the radio starts rebooting and doesn't pass the splash screen. also makes noises on the speaker.. the best is to disable the power from the programmer and power the radio from it's own battery when programming.

My other programmer works if I set it to power the radio because it only applies power when programming and not all the time as the UsbAsp. That's why I think I never noticed this problem before.

What voice card have you got? Is it a homebuilt? Or an Emartee one or the MegaSound 9X from HC1969?

please read attentively when I disconnected Audio (voice), the equipment earned in all modes normally.


p.s.

I think there will be one more problem, think LCD won't work in the trainer mode!

most likely the problem arises because of lack of a food on the voice module in all specified modes!

I did read what you wrote. Not that I can understand it. But you still didn't answer my questions.

I answer your question
without the Audio module (voice) the equipment works perfectly
in all modes

[jhsa]

How do you power the radio? Does the radio work with audio when is not connected to the computer? Trainer?
I know it does work in all modes without the audio..
I want to know if there is a mode that it works WITH audio??
I repeat my question again. Do you have a battery in the radio?

the battery in the equipment is installed.
At connection to the computer (a simulator, the trainer) audio doesn't work.
In a usual mode the voice works perfectly.
In a usual mode the radio channel works perfectly.

where did you connect the power (V+) to the Voice module? a good picture of your board would maybe help..

(+ V) connected to the beepper T-module, an entrance of a chip 7805

[mhotar]

Good target from jhsa. There is no power there in simulator mode, that's way it breaks LCD function also.

[jhsa]

Correct, When you are in trainer mode the power switch it's off, so, your board is not getting any voltage..
Connect the power as in the picture on the link below.. Red wire connects to the orange capacitor.. There is Battery +V even when the tx is in trainer mode.

I made here it, and everything earned perfectly!



all thanks!

yep..

[tigar]

Well done Jhsa translating google translate!

[Redbrickman]

What is the best option for an audio board now, as I notice there are a couple of boards available. Main thing for me is to avoid too much construction work as I'm not great at building circuits

[tigar]

I think one of the best solutions right now is this

http://www.ebay.com/itm/MegaSound-9X-Vo ... 1c30d66f39

It is cheap and it works.

[tilmanb]

Availability seems to be the key. Feature wise they are pretty much the same.
Meaning, the one you can buy is the best one.

I just bought a megasound9x voice module and was wondering is it best to put it in the 9x - the one I repaired thanks to this forum and now running great - or in the newly arrived 9xr, which I'm going to flash with er9x. I'm currently using the stock turnigy module in the 9x and have a FrSky DF Combo pack plus a FLD-02 screen and 7db antennae for the 9xr. I'd like as much telemetry to come via voice as possible, so the 9xr seems the best bet. Is the installation same for both tx's? Any advice appreciated.

[jhsa]

for the voice module to work with telemetry you must do the frsky telemetry mod to the radio. It won't work with the FLD-02 screen..
I would say the best would be to install it in the 9x.. Don't know if the 9XR has enough space for it, plus the telemetry mod..
Also you could get the telemetrEZ board and go solderless if you have already the smartiepaRts board, or almost solderless if you don't. It allows you to have on screen telemetry without soldering to the processor pins.. Again the 9XR has very limited space inside for all this.

Thanks jhsa, I don't have smartieparts but I'm reasonably competent with a soldering iron. I was going to put the FrSky combo in the 9xr as I read somewhere someone had put this voice board in a 9xr but I think I will follow your advice and stick it in the 9x. Will the turnigy module from the 9x run in the 9xr? If so I'll swap it over and wait for the new 9xr one to arrive.

You seem to be hot on the voice mod, what setup are you using and what do you use it for most? Apart from bragging rights at your club which is a given

Thanks jhsa, I don't have smartieparts but I'm reasonably competent with a soldering iron.

I mentioned the SmartiepaRts board and the TelemetrEZ board because you mentioned the FLD-02 screen. Normally people that can't or don't want to solder get that display or the DHT-U.
The problem is that with those you won't have per model settings telemetry while if you do the telemetry mod with or without the T-EZ board you will have on screen telemetry on the 9x, and will be able to set alarms on a per model basis. T-EZ still not available for the 9XR but I think Steven is working on it.. Also the voice module will only work with telemetry if you do the internal mod. Not with the displays..

In many people's opinion the 9x is a better radio but I'm not commenting on that. In my opinion the lack of space for mods inside is very limiting
As far as I know the turnigy module will fit but I've read that some people had problems with it.. something with having to bend the pins??

Yes, this mod is quite special for me.. It was a big fight trying to convince the developers and half of RC Groups (at the time) and also this forum that it was a great idea..
Thanks to Mike's flash savings, his knowledge, and all the time he spent working on it, we are now able to enjoy the voice capability.
Also thanks to Oliver for starting the new voice module's project when the emartee new modules suddenly didn't work as expected. He is the real father of the MegaSound9x module..

At the moment I have two 9x radios modded with Atmega128, rotary encoder, MegaSound9x boards, HaGeHa's version, the self made one not the commercial (thank you Hans for etching a couple PCBs for me. Yoy get to know very good people in this forum), and I use it for all the telemetry alarms and also telemetry reports, like voltage, altitude, temperature, etc.... You just flick a switch and it repeats the data every "n" seconds.

Of course you can also use it for all the ridiculous (I've been told at my club) stuff like telling you that your flaps or landing gear is down, or that your throttle cut is active..
All this might not be necessary but I like it and I have fun with it..
And it's cool

There are other possibilities like for example, having the airplane doing something using the telemetry.
For example some users from this forums are limited to an altitude of 400ft due to their field's proximity to an international airport..
You can have an altimeter triggering a voice alarm letting you know that your model is too high, or even turning the motor off if you try to fly above that limit..
All together this is just a wonderful system..

Sorry for the long post. I hope you can find some useful information in it.. that's rare on my posts

Hi Everyone,

I just bought a MegaSound board from ebay.
My problem is that to solder the wires on the radio at points D0,1,2,3
looks very difficult for my old eyes, looking for someone here in the states
that could do those connections for me?

Thanks,
Darrell

Fut*ba ? I don't need no stinkin Fut*ba!

[MikeB]

I got some cheap *3 reading glasses. By using two pairs together, you can get a good view of the soldering operation.

Hi Mike,

That is a great idea but what if I am shaky too?

I have the same problem, so when I did mine, I've built a jig to attach the radio to my hand so it would shake all together..

Sorry, it's a joke, a bad one, but couldn't help it.

I do shake a little bit (now a bit less since I stopped smoking), and it's difficult to hold the hands steady when soldering..
when doing the telemetry mod and soldering the wires to the processor pins it was a pain the first times because the iron movement would cover about 3 or 4 pins to each side of the one I was trying to solder but I got it done.. Just needed to practice a little bit..

If you don't feel confident and are afraid to ruin you tx, the best is to do what you did and ask for help.. I'm sure someone near you will offer to do it for you.

If you get stuck. I would be happy to come over and do it all for you. I only ask that you cover the air fair, hotel accommodation and bar bill.

[glopro]

Thanks yet again, Jhsa - long post?? I was glued to every word Have ordered the the bog standard TEZ and I'm hoping it will do at least some of the things you mentioned. I only have the standard Atmega64 proc installed as well. Anyway should be fun.

It is incredible what people have done on here to transform this dodgy bit of Chinese kit. Respect and long may it continue.

[jhsa]

Amen..

The T-EZ is for the telemetry.. You will still have to do some little soldering to connect the sound module.. Not as bad as soldering to the processor pins though..

I would also like to express my thanks to the developers!
