Hi João,

Do you have a diagram or photo of the back of the single board version?
I want to make sure the shunts and opens are in the correct spots.
Thank you,

Joe

Sorry for the late answer. Is this what you need?

Thank you, João

It Kind of does João,

I guess its the newest version but I see now you added a 10U Cap and different Transistor ( which I don't have that transistor )

I'm building the 2 board version at the moment and will give that a try before building the single board.

One question is do you have to do the speaker mod for this to work or will installing the ArduVoice bypass the old OEM beeper/speaker

Not sure I understand, I believe I always used that transistor, which if I remember, switches the backlight..

No need for speaker mod the beeper signal is fed to the arduVoice board, and it will be played through its speaker.

João

Hi João,

Sorry, I meant the transistor is in a different spot, you have an extra 10uF Capacitor on the latest diagram you just posted.

I don't recall seeing it on the first page, I think there were only a 10uF and 220uF cap on the first-page diagram.


I was thinking the voltage regulator was different but its the same 7805. It just looks bigger.

Joe

it's been a long time since I last played with this

João

Yes João, I realize that and again I thank you for taking the time out to reply.

Just an update.
I'm going to build the 2 board design first.
I'm working on the Amplifier board and have completed the Arduino board minus connections.
I just rechecked my work and noticed I used the wrong value resistor for R9 so I found the correct one and swapped it out.

Joe

Hi again,

I realize this is an old thread but can someone help with loading the bootloader please?

I have an Arduino Pro Mini
I do not have the completed module in the transmitter yet and figured while I had it out I can install the Bootloader.
I have tried using my USBasp programmer with eepe but get a sync error and I don't think anything is getting loaded.
Also I'm not sure if I'm supposed to see a com port using a using my USBasp programmer.

I think you can use the Arduino IDE program to flash a bootloader but you have to manually add it to the board file which I am not 100% on how to go about that and where I would get all the files needed.

Thank you for any help or suggestion.
I have checked to make sure everything was connected right and it is and have read this thread like 3 times.

I believe I used "AVR Studio 4" to flash the bootloader. But I had another programmer, not the UsbAsp..
never did it with the arduino IDE, so I am not of much help unfortunately

João

Ok thank you I will look into that.
There is also something called ARVdudess as well

Thank you as always

AvrDudess is a GUI frontend of AvrDude, and works quite well.

Mike

OK I have tried to load the bootloader with my USBasp but nothing can detect the arduino.
The USBasp is loaded correctly with the right drivers. I used it to flash ER9X to the radio.

I double checked all connections and checked the 6 cable to make sure they are ok.

Is there a way to burn the bootloader using FTDI adapter ? I can flash blink sketches to the pro mini and I see the light timing change so that's working.

I don't understand what I'm missing

I think I got the bootloader and firmware loaded. ( I am not sure how to tell for sure until it installed ) Is the LED supposed to blink after flashing it ?

I used a different laptop (Windows 7) that had Bitburner on it.

I loaded the Bootloader (EEPROM) first then the Firmware (Flash). I hope that's the correct order?
It worked!
I also tried AVRdudess and it worked as well. ( I was logged in as local admin on my Windows 7 laptop if that matters so keep that in mind )

Ok, now its time to wire the card to the radio and hope it all works.
I'm guessing something didn't like my Dell Windows 10 laptop for some reason or you need to logged in using the local admin account.

I have 2 questions :
1. Should I remove the 2 resistors at pin 27 & 28 on the board
2. Should I remove the OEM speaker and run the tone input to the soundcard or leave it be? Does it matter? (
I did order vibration motors to add them as well but they must be coming over to the USA on a slow boat

Hi, after your recent PMs, thought I’d have a look in here as it’s been some time....

Regarding your questions:-

1. I didn’t remove the resistors on mine and all seems to work ok.
2. I did remove the original beeper and connected to the new board instead. Beeps work well.

The only thing I haven’t got working yet is the volume control from one of the pots....must be doing something wrong!

Hope that helps.

Cheers Don

A question on the Trim connections ?

In the photo on the first page it says to connect to pins 27 & 28 on the main board but it looks like its actually soldered to pin 28 and 29.
I just want to be sure before going ahead and soldering to the resistors.
The schematic for 9X radio shows pin 27 & 28 as the 4th and 5th in that row on the photo on page 1. When I am looking at my board its the 4th and 5th resistors as well.
I attached schematic photo - this is how I see it on my board as well

Count the pins. It is definitely pins 27 and 28.
I will try to post a picture when I get to my computer.

Go to "Model Setup / General", Scroll down to "Volume Control" and select the Pot you want to control the volume with.


@Mike
I have just tested this, the volume pot works, but I can't turn it down to completely mute it.. Is this normal?
Thanks

João

Joao,
Is the photo for the trim connections correct? It looks like 28 and 29 ?

The photo was actually originally posted by Mike, so yes, it is correct. You are obviously not counting the pins correctly. On the picture, the first pin at the bottom near the crystal is pin 17, top one is 32. Follow the tracks and you will see that those resistors are connected to pins 27 and 28..

João

OK its the pins for the CPU. Thank you I wanted to make sure.
PIN 27 & 28 are ElevTrimUp & ElevTrimDn

That is on mode 1. They are the throttle trim on mode 2. They are the left stick vertical trims to be more precise..

OK everything is installed and the sound board powers up.
I removed OEM beeper and transistor.
I get a beep when powering up from ArduVoice.
I enabled M'sound serial in hardware mode and changed mode sound to Megasound.

How do I setup what file plays for whatever switch is toggled ? Or is that the program that the Arduino is running? If that's the case I have no sound.

Does the FTDI adapter need to be connected? I think I had RX & TX connected to it but no ground. I'm hooking up the ground as I post this.

Hi Joao, thanks for your advice....I had already done that but have now realised that altering the setting of the volume control (P1) only takes effect for the “next” voice file to be played....I had initially thought it would work “during” a voice file.
All is ok now.

Cheers Don

Hi, I haven’t got an FTDI adapter installed inside my Tx, leaving a connector in the battery bay to be able to plug one in if required in the future, so no that doesn’t have to be connected.
The voice files are stored on the micro SD card and are all numbered. To allocate a voice file to a switch for instance, go to “Model Setup”, “Voice”, select a line to use/edit, set the “Source” (example CH5 which could be controlled by a switch), set the “Function” (example v~=val which means variable is approximately equal to the value), set the “Value” (example 700), set “On no Telemetry” to Play (so this works without having any telemetry from a receiver), set “FileType” to Number (so it chooses one of the numbered files mentioned earlier), set “Voice File” to your chosen file number (example 160) which should play “Throttle Cut Active” if the switch moves CH5 to a value near to 700.
After all this, it’s just a matter of playing around!

Cheers Don
Now if the switch is used to set a value of 700 on CH5 and the

Hi all,
Ok I ripped everything apart last night after noticing no change on the Arduino led when trying to play a file.
I may have reversed pins 27 & 28 to the Arduino not sure and also possibly the trims inputs.
The other thing I noticed is that the Aileron switch didn't change status after adding the sound board. ( I think I added a sound board ground on the main board in a spot I shouldn't have not 100% )
After fixing all the inputs to the arduVoice board I saw the led flash finally indicating it was doing something.
I tried adding the 20k resistor on the SD card reader I saw someone posted about but that made no change.

I thought the beeping was coming from the speaker but realized it was the DHT module speaker ! Duh !
I then suspected the speaker was bad.
I think the speaker I used wasn't new but something I had laying around so seeing it may be bad I switched it out with a brand new one and to my delight I have sound now !

Thank you all for all the help and suggestions.

Joao I watched your video on YouTube from 3 years ago that tipped me off to the LED on the Arduino flashing when it plays a file. Its the one that shows how to setup the switches to play a file off the SD card.

I was up for hours but got it done - the wife asked what time I went to bed last night and I said I don't know I didn't look at the time,
Beside I didn't want to know at that point....

I have one more to build for my TH9X now with an Atmega128 - I will post a photo of the next board when its done.

My other TH9X is an Atmega64 can you do the sound card in it or is there not enough memory in it?

Hey, well done Congratulations

I do know what you are talking about.. When I am working on something I completely forget about the time. That is why people see me replying here on the forum at any time of the night or day I had already a few people asking me if I sleep at all

It's been quite a while, and Mike could probably answer this better than me, but I think there is a special Er9x version only for the voice over serial. This version is only for the m64 processor..

I have just checked on www.er9x.com and the file is called "er9x for M64-FrSky with serial voice"

João

I made another sound card its basically 2 but on one board.
I attached a photo of it before wiring it.
Thank you for making sound happen Joao & Mike

It is not only sound you can have 2 extra switches with the ArduVoice I installed 2 pushbuttons on the back of my radio
