Hye,
First of all thank you for your very nice documentation ! I had a look 2 years ago and everything seemed to be in an update process.
From what I understand, quite a lot of knowledge is needed before enjoying FF. Let me say as an excuse or a "Joker card" that I am absolutely not a hardware man, even if I have put my hands years ago in these kind of stuff. I remember that it was all hell and pain, and no pleasure at all. Beside this, and because of plentyfull of documentation and already made Arduino shields, I feel comfident for connectiong a FlashForth Arduino to external things.
To be concise, and after my presentation, I have seen on the http://flashforth.com/atmega.html link the sentence:
"Preprogrammed Atmega328 chips with FF for the ArduinoUno R3 can be ordered from oh2aun at gmail.com .
Just pay 10EUR or 12USD to oh2aun at gmail.com (PayPal), include your postal address and I will mail you a preprogrammed Atmega328 chip."
"Bingo" it is for me, as I will not go through heavyloaded hassles. I can have a ready to work Arduino with a terminal emulator.
Here is my request:
Is the above offer still available ?
I need 2 Atmega328p (in case 1 is burned for any reason or error on my side).
If yes, what will be the cost for these 2 atmegas knowing this adress near Paris:
Guy Fortabat
4 avenue Charles de Gaulle - esc 5
78230 Le Pecq
France
Some more question to be complete:
I had a look on Atmega1284p Bobuino from Crossroadsfencong.com
This company is on your side of Atlantic Ocean.
I know that my asking is perhaps not receivable, but any way I'll try ;-))
I can buy him 2 boards (fully tested by him) to be sent to you, can you flash them with a 1284 build ?
Maybe I am on the way to take the exit door .... ;-(((
Feel totaly free to refuse, I can unsertand. It is the only way for me to avoid hassles like in the past.
Best regards from Paris

Sure I can mail two pogrammed chips. 20 EUR total cost.
Maybe Bob could program the Bobuino directly with FF before sending it to you ?
I can support him with a hex file if needed.
Much easier than mailing boards around.

Hi Mike,
Thank you very much for your positive answer about 2 preprogrammed Atmega328p. I will send you the fee requested through Paypal.
If I am positive about this experience, I will go on the Bobuino side in a second time or on the atmega2560.
By the way I have noticed one inconsistency in http://flashforth.com/atmega.html
Is is written:
"For the Arduino boards there are two hex files in the avr/hex directory.
The ff_uno.hex file is for the Atmega328P and the Atmega328 chip on the Arduino UNO board. Fuses should be set to E:0xff H:0xda L:0xff
The ff_mega.hex file is for the Atmega2560 chip on the Arduino MEGA board. Fuses should be set to E:0xff H:0xdc L:0xff"
......and 10 lines below ...........
"$ sudo avrdude -p m328p -c stk500 -P /dev/ttyACM1 -e -u -U flash:w:ff_uno.hex:i -U efuse:w:0x07:m -U hfuse:w:0xda:m -U lfuse:w:0xff:m"
You see the difference about the first fuse ? 0xFF vs 0x07.
Wich one is the correct one, and maybe it is the same for Atmega2560.
What shall we read for both processors ?
Best regards Mike, and thanks again for the 2 preprogrammed chips.

Sorry, but you paid 20 $, It should have been 20 Euro.
Both fuse values are correct, the upper 5 bits of the fuse are not used by the 328.
It is just a question of the how the tool that sets the fuses behaves.
I quess 0x07 can be used in any tools.
I paid the difference Mike.
Sorry for the mistake !
Happily waiting for the chips,
Guy
Great.
I'll send the chips soon.
Put two chips in the mail today.
Mike
Hi,
They arrived today 07/04, and they work like a charm !
Mess and hassles are behind me now, this is great ....
Thanks a lot Mike !
