ArduVoice-9x Voice Module with Arduino for the 9x Radio
Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
What audio amp are you using?
You don't seem to be using the filtering circuitry between the atmega and the audio amp. Please take a good photo from the atmega board. I have the feeling you are not following the original schematic at all.

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
Dear Joao,
Sorry for inconvenience.
Audio amp PCB all same as schematic, it is work (speaker bip when power on). The filtering circuitry between the atmega and the audio amp are SMD part solder on bottom size of PCB.
I flashed the module with the serial adapter by connect 3 wire (TX, RX, Gnd) from USB UART to Arduino Pro Mini and flashed successful (Pls see attached picture). This serial adapter I used to flash openXsensor PCB as well.
I have tried flash the combined firmware by ISP programmer as on the first post "combinedSerial.hex" but the result same as when I flashed "Bootloader_optiboot_atmega328_16.hex" by ISP programmer and then flash "Firmware_amod_lastSer16.hex" by serial programmer.
My Your SD Card reader add LC filter on 5V line as i read on this thread. This SD Card reader work well (I have tested with Arduino nano PCB).
Thank you for your help.

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
Are you using the LM386 audio amp? It does not look like it on your picture.
Again, please post a picture of your atmega board. I would like to see what you have in there..

Dear Joao,
I used LM3886 straight line pin for audio amplifier.
I will post all pcb pictures next week because I left them at my company.
Thank you, have a nice weekend.

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
Dear Joao,
Some update...
The sound module only work after power on the Tx and press reset SW on Arduino Pro Mini many times. But SD card not work as well.
If i touch on R4 on Micro SD card adapter, it work.
Do you have any idea.
Thank you,

I think communication between ATmega328 and ATmega128 at power on is not good. Now I connected reset SW to outside, power Tx on and press that SW 2 or 3 times and everything work well.

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
I don't remember seeing that happening when I did it. I know I had problems with an arduino nano, but not with the pro-mini..
Maybe Mike has an idea why you need to reset the arduino.
Did you remove the resistors on pins 27 and 28 of the radio processor? I did remove mine, and as far as I remember it did solve some problem, I just can't remember which problem.. Maybe you should try that..

You have the diode between pin28 and the arduino, right??
Check that the anode is on the arduino side, and the cathode connects to pin28 of the processor..

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
Hmm, I don't know, I'm just guessing here. Do you have the bootloader installed?
I'm out of ideas. It is difficult when you don't have the hardware in front of you..
João
Edit: do the trims and the backlight work before you have to press the reset button?

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
Dear Joao,
I have tied two way:
1. Flash bootloader by ISP first and flash firmware by serial.
2. Flash combined (firmware and bootloader) by ISP.
Both have same result.
Trims and the backlight work after I press press the reset button.
Thank you so much for your help.

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
hello,
I want to build my own arduvoice. But I dont understand one thing. How is the throttle trim exactly wired after the modification?
And can you only put models from pc to tx and from tx to pc or could you flash the tx with the serial port (this would be really cool).
Big thanks to you guys, João and Mike

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
The 2 switches from the throttle trim connect to pins 2 and 3 of the arduino. Before they connected to pins 27 and 28 of the atmega 64. But these pins are needed for the serial communication between the module and the radio, so the trim was moved to the arduino.rcfish wrote:hello,

It has been a looonnng time since I've played with this.. I only have one radio with this installed, and it was a long time ago, so I don't remember much about it But I remember flashing the radio's firmware with a FTDI adapter. But I don't think this was related to the sound module. It is a different connection and I think not all the radio boards have the bootloader. I don't think the M64 has the bootloader, so flashing with the FTDI wouldn't be possible in this case.. Mike could probably confirm this..And can you only put models from pc to tx and from tx to pc or could you flash the tx with the serial port (this would be really cool).

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
Do you have a '128 processor? If so, then the .hex file (er9x-128.hex) includes a bootloader that gets flashed to the top of the flash space. This uses the telemetry serial connections at 115200 baud and should work without needing the arduvoice module.

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
Hello.
I have installed the frsky telemetry mod and I want to install arduvoice now.
do i have to flash er9x-128-frsky.hex or er9x-128.hex?
and can i just use the normal arduino bootloader?
and con you flash the .hex files from arduino ide?
er9x-128.hex is including a bootloader for serial programming (with ftdi not with usbasp) (if this is right). What pins on the processor are the one you use for this? 27 and 28?
thx for the help

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio
where are you getting those files from? er9x-128-frsky.hex doesn't exist anymore. Please get the firmware files from www.er9x.comrcfish wrote:Hello.

Then after installing the er9x-128.hex, go to the hardware menu and turn ON the option "Frsky Mod Done"
To enable the hardware menu (it is protected) turn the radio on while holding the left horizontal trim to the left. >Release the trim after a second or two. Now the hardware menu can be accessed.
Mike can answer this better than me. It has been a while since I done thisand can i just use the normal arduino bootloader?

None of them.. those are used only for communication between the voice module and the Atmega128.er9x-128.hex is including a bootloader for serial programming (with ftdi not with usbasp) (if this is right). What pins on the processor are the one you use for this? 27 and 28?
To flash the m128 using an FTDI adapter and the bootloader you connect to pins 2 and 3 (MOSI and MISO).

If the Arduino IDE can select a .hex file and flash it, without compiling first, then you may flash it that way. You may also use eepe as the "front end" to do the flashing.
