Rob, what build has the sounds in your utube post?

All current builds.

You just have to make sure you

speaker mode is set too PiSpkr, and the

frsky alerts too:

Int. FRSky Alarms : on

Then you can select the red/orange/yellow alert tones.

Hi, all!
I believe that there is more than information on yellow, orange or red level of alarm (and besides about many other things) it is possible to receive from the speech speaker. Speech, instead of sound, though and with different tone. On a sound even different tone it can be not clear about what warns a buzzer. And if the transmitter a pleasant female voice informs us that for example: "you come nearer to a zone of uncertain reception of a radio signal!" That it will be fantastic. And it is very convenient.
I have no experience of working out of such equipment and mod and very much I hope that colleagues at this forum can offer similar mod.

This sort of feature is planned for the new main board. (ersky9x)

The current hardware / firmware space is too limited to do fancy audio.

That's it, you just broke my heart.. before (still at RCGroups) it was said that there was enough space for that, and now suddenly there isn't?? Mike was even thinking about releasing some pins for that and The PXX, and also we would have some extra pins for other stuff..

Huummmmm...
I hope that some thoughts that just came to my mind are not true, because it wouldn't be fair on people that can't afford the new board. I'm one of them..

Depends on what specific feature you want.

Problem is there is not really any room for adding much in the way of menus to configure any of these alerts.

So at best we could trigger an MP3 to play for an event. But dont expect anything fancy.

You would not for example be able to select an mp3 to play for a specific event.

Just trying to keep expectations realistic

. There is only about 4% of space left on the firmware.

I haven't given up on the audio. The mod I have in mind is quite messy, a lot of modifications need to be done, not everybody will want to do them. We can get some space back if we don't have the templates, it is a compile option to leave them out, but keep the heli. We may get to a point where if you want special audio and FrSky, then you can't have templates. I've been working on slimming the code again, gained a bit back.

I have an idea for adding audio on, need to get it more solid before I suggest it.

Mike.

Hi Mike, thanks for giving us some hope..I personally don't think that the templates are needed in the tx because we have eepe. Another idea ( i don't understand anything about coding) would be maybe to leave the speaker and ?vibrator? part of the code out as well? or at least part of it? to save some space? the reason I say this is that if you have the audio you won't need any piezo I guess.. Not sure about the vib, that's why I wrote it in between question marks..
Thanks again..

João

I suspect this will need to be left in. (or the bulk of it)

The actual code that drives the speaker or buzzer could be excluded - but will only remove 20 or so lines of code.

I'm going to try to summarise regarding an addon to give speech output, and then we can work on from there.
1) We need something to play the speech (what quaility?, we don't need hifi, what format of audio file?, how much?)
2) We need somewhere to store the audio files.
3) We need a method for the ATMEGA64 to request an audio file to be played.
4) We need a way of getting the audio files onto the storage.
5) The addon hardware should be easy to obtain/make, and be readily available to all.
6) If any addon needs to be programmed, how is this to be done?
Remember different people have different hardware mods already done to their TX.

I think we should try to keep this simple, don't complicate it with trying to get any addon to provide anything except the audio function. There is enough to do with that.

I have some ideas, for some of this, but whether they are appropriate depends on choices made to the questions.

Mike.

You know it, Droid Builder, arduino and tts goodness

demo

Post by **jhsa** » Tue Jan 17, 2012 4:12 pm

someone posted (on RCG) already some modules that use sd card. we could then play our own files, in any language..
I think this is the way to go.. As far as I remember they weren't that expensive..

Rob, this one was posted by you..

And this one posted by ReSt if I'm not mistaken.. He did some experiments with it..

http://www.emartee.com/product/41928/MP ... d%20Module

It's from the same shop that sells the one above. but is nearly half of the price..

Post by **cre8tiveleo** » Tue Jan 17, 2012 4:46 pm

I like this one... Smaller, half the price..

That would be cool.

1) We need something to play the speech (what quaility?, we don't need hifi, what format of audio file?, how much?)

This is the card that I experimented with
You have to order the module for two wire serial protocol.
http://www.emartee.com/product/41928/MP ... d%20Module

Sample file of output quality is attached here
http://www.rcgroups.com/forums/showpost ... ount=14442

2) We need somewhere to store the audio files.

It has an SD Card for the audio files

3) We need a method for the ATMEGA64 to request an audio file to be played.

Audiofiles are named with numbers 001.ad4 to 510.ad4
you play them by just sending their number to the module

4) We need a way of getting the audio files onto the storage.

Put the card into an SD card reader attached to your computer and copy them (card is FAT formatted)

5) The addon hardware should be easy to obtain/make, and be readily available to all.

is available at emartee.com and maybe others (I bought it on ebay .. (from emartee))

6) If any addon needs to be programmed, how is this to be done?
Remember different people have different hardware mods already done to their TX.

No programming required on the card side.

Programming for the TX should be done, so a compile switch adds the required code if wanted.

That worked for me (from my PC):
http://www.rcgroups.com/forums/showpost ... ount=13643

You will need two output lines (clock and data) to communicate with the module. There should be a third line (input) to monitor the busy signal to know, when playing a soundfile has finished (required if we want to add several partial sound to one complex message),
It could be possible to switch direction of one output line to input to monitor the busy signal, after data has been sent completely.

I think we should try to keep this simple, don't complicate it with trying to get any addon to provide anything except the audio function. There is enough to do with that.

This solution is simple and allows nothing else but to play sounds.
(You can put in a card with your favourite songs, add three little pushbuttons and you will have an MP3 player).
Power can be supplied from 5 volt by reducing it via a red LED.
Clock and data line should run over a little voltage divider (I used 1.2k : 3.3k )

This could be used to say numbers.. it would reduce the number of files needed.. also for saying the type of info the numbers are associated to like altitude, voltage etc..

Mike,

Believe you already have one of those from emartee. Gave it to you when we saw each other last

I meant to look into it more over Christmas - but had no time

simple hardware: http://www.adafruit.com/products/94

available to anyone? yes

program needed to be made (probably from scratch)

no specific IC's or re-branded controllers. just an atmega328 and a DAC (ignoring the audio amp cos' its just and double amp-op)

price: forget it. its nos cheap, but you can buy the parts yourself and make it cheaper to you. if you don't know how? simple. save some money, then buy the shield.

bulky? yes. its huge. but its done and it works right?

low sound output? no problem.

add this: http://www.ebay.co.uk/itm/Mini-Capsule- ... 3f11997018

of this: http://www.ebay.co.uk/itm/3-5mm-Mini-Po ... 218wt_1272

btw. this would be interesting to do over I2c cos' the arduino supports it.

later on you could even plug a wii motion plus on your 9X to use as head tracker or other functions. (probably not but I wanted to say it! )

Yes thanks. I notice it says supports a max of 1Gb SD card. Now I don't have a standard SD card, only a 2Gb micro SD without adapter.
So I have a question, will this device work with an SD card larger than 1Gb, even if it only uses 1Gb of it? 1Gb cards look to be less easy to obtain these days.
If we use this, others need to be able to get an SD card, to make it work, easily.

Mike.

Post by **cre8tiveleo** » Tue Jan 17, 2012 10:27 pm

It probably works with 2gb cards, and select 4gb cards, not sdhc. Just standard sd cards. 4gb cards are usually sdhc even if not marked. Fat 32 cannot handle a file larger than 4gb... (fat32 can handle a 2tb drive though)

Post by **cre8tiveleo** » Tue Jan 17, 2012 10:36 pm

Dealextreme has 1gb sd, tigerdirect.ca too

ReSt · Post by **ReSt** » Tue Jan 17, 2012 11:35 pm

Just verified that 2GB SD card works.

But my 2GB micro SD card with adapter does not work.

Reinhard

Post by **MikeB** » Tue Jan 17, 2012 11:46 pm

That's a pity (2Gb micro card in adapter). I was going to try to sort an adapter for my micro card for this. I wanted the micro card for ersky9x, I'll probably need an adapter anyway, but if it won't work in the sound module, the sound module may be a bit restrictive.

Mike

Post by **cre8tiveleo** » Tue Jan 17, 2012 11:50 pm

Then why not the snd crd with micro adaptor then? It's there too

hi there...

is there a way to have the same alarms as frsky in stock er9x?

like choice of bootsound,
counter alarm choice,
alarm choice ect.

cheers

This is what it looks like.
Here is link to the sdcard sound module.
Same as cre8tive leo showed , but even cheaper.
