Build Compile amod [Please help]
Re: Build Compile amod [Please help]
Is that correct ???
Do I need to solder Before resistor or after ???
Or do I need to remove them ???

Re: Build Compile amod [Please help]
It's wrong. You marked pins 25 and 26 of the atmega.. You need to solder to pins 27 and 28 of the atmega..
On my voice module I had to remove the resistors.

Re: Build Compile amod [Please help]
Thanks for your reply .
But here is TRIM port connection to chip Like Mike Suggested to connect Trim pins to X1 & X2 instead of Megasound
Serial to magasound go to pin 27 & 28 and this what I have.Just possibly, the firmware you have is looking for the trim switches on PORT C, bits 2 and 3. My original circuit shows these as connections X1 and X2. You could therefore try connecting the trim switches to these.

And if I'm not mistaken, Pin 30 (RX) of the Atmega328 connects to pin 28 of the m128
and Pin 31(TX) of the Atmega 328 connects to pin 27 of the m128

Re: Build Compile amod [Please help]
The trim switches that connected before to pins 27 and 28 of the Atmega 128 connect now to the voice module, atmega328 pins 1 and 2, again if I'm not mistaken.
Pin 1 is Thr trim up
Pin 2 is Thr trim down

Re: Build Compile amod [Please help]
Serial works communication is fine to PC I can upload files without problem.
Problem I have and it looks like Mega Sound don't talk with Atmega128 for some reason ;(
Regards
Re: Build Compile amod [Please help]
Don't work That way
That what I got now and its not working
Every time I touch TRIM switch its just makes speaker to make weird noises
Regards
Re: Build Compile amod [Please help]
Are you sure you connected the trims to pin 1 and 2 of the voice module, and connected the voice module to pins 27 and 28 of the radio's processor? Your picture above is wrong..

Re: Build Compile amod [Please help]
Do you have the FTDI always connected to the voice module? That won't work without a diode or two. Try disconnecting the FTDI adapter..

Re: Build Compile amod [Please help]
Attached pictures is for TRIM connection as MIke Suggested
And all connected like this
PD2 - Pin 27
PD3 - Pin 28
Atmega328 pins 1 & 2 connected to TRIM wires
I have posted some videos of what it do when it turned on.
And FTDI is disconnected when no needed

Re: Build Compile amod [Please help]
Please try connecting
m328 PD0 - Pin 28 Radio
m328 PD1 - Pin 27 Radio
PD3 and PD4 on the m328, to the trim switches.

And if there is any FET transistor on the m328 serial lines, remove it and bypass it.

Re: Build Compile amod [Please help]
There is one diode on ATMEGA328 PD1 should I remove by pass it??
Regards
Regards
Re: Build Compile amod [Please help]
yes, bypass that one. PD1 connects to pin 27
Put a schottcky diode with the Anode on PD0, and the cathode connects to Pin28. But you can try without the diode before. Don't connect the FTDI. You will need that diode and probably another one on the FTDI line later.. but before test without to see if it works

Re: Build Compile amod [Please help]
Hi all again
Got some success here
GOT AUDIO FINALLY but not there yet
So came back home recompiled hex with TEST 1 flashed boom playing.
But only playing file 40 (Dont do anything if i press from 0 to 9)
Back light same always on.
So recompiled to TEST 0 back where started ill try to remove diode to see if it makes difference

Re: Build Compile amod [Please help]
When you press 1-9 (remember 0 drops you to the bootloader so if you tried that first you stop the board playing anything), do you get 1-9 echoed back?

i get nothing echoed back
just line off XXXXXX"Euro sign"XXXXXXXXXXXXXXXXXXXXXXX ans so on looks like euro sign shows up when its start to play soaund again
So board works just tripple checked connections all as required still no joy
Wired TRIM lines to X1&X2 Trims working now fine.
Audio as it was no difference still just ticking just dont get it ((( ((((((((((((

Re: Build Compile amod [Please help]
If you don't get the 1-9 echoed back, then it seems the character you typed isn't getting to the Megasound processor.
Another check is to type the ESC character, and you should get a 'E' echoed back.
Can you still upload files OK?

Re: Build Compile amod [Please help]

Just tried E S E and more nothing Echoed back
File upload works fine just have to re flash to TEST 0 to be able to talk to SD card
The way im testing is keep renaming different file to 0040 and uploading to sd via EEPE
And all files play fine

Re: Build Compile amod [Please help]
If the trims are working, it means that the megasound is now working and the communication between radio and voice module is also working.. Why don't u just flash the normal file??

Re: Build Compile amod [Please help]
If i flash standard amod_ser_hex it stops working radio wont do any sound at all just ticking speaker that all. Here i hit wall cant figure out what to do now

Re: Build Compile amod [Please help]
Did you put the diode as I described? Did you remove the resistors?
If you flash "amod_ser_hex" do the trims and backlight work? (Just connect an LED, doesn't have to be the backlight itself)

Re: Build Compile amod [Please help]
Pins 25 and 26 from where??
Attached is the schematic from my voice module with arduino, and a picture with the pinout of the Atmega328P and the corresponding arduino pins. If you don't connect the things as they should be, IT WILL NOT WORK..
Do you have the schematic from your board? Ort at least a link where i can get it..

Re: Build Compile amod [Please help]
No, I suggested connecting the trims to pins 25 and 26 of the ATMEGA328 on the megasound board.
You say the backlight is working. Can you turn it on and off by assigning a switch to the backlight in the Radio setup menus and then using the switch to turn the backlight on and off?
For when using the TESTING firmware, please confirm you have the files 0001.wav to 0009.wav on the SD card.
I'll get back to you with some test firmware, probably some time tomorrow.
Mike.

Just checked Backlight but seams to be ALWAYS ON dont response to settings
And pins 26 25 do nothing on megasound do i solder wires direct to pins???

Thanks for your time ill do that first thing tomorrow.
Got to much of this mod already.Loosing patients trust me never ever had such a frustrating thing in my life
All look like works but in same words not its like sayin YES&NO that what i get now
Thanks again!!!
