I joke, I'll sleep when I'm dead, but I'm also pretty sure my wife will donate my body to science just to get more use out of me

its ok i'm on holiday so razor sharp

provided the following legend by Mr. Kramar I decided to geek out a little bit and create this cheat shit

Address 0x304 Data0 is an unknown at present, but seem to be 40 or 48 in the Volt.
Address 0x304 Data1 is the current commanded, convert to decimal and divide by 20.
Address 0x304 Data2 first 2 bits are MSB of the voltage command.
Address 0x304 Data3 byte is the LSB of the voltage command. Then MSB LSB is divided by 2.

Desired Amps	Hex in Data1
1	14
2	28
3	3C
4	50
5	64
6	78
7	8C
8	A0
9	B4
10	C8
11	DC
12	F0

I think 10A DC out is what you can expect the most. But AC amps vary if you use 240Vac or 115Vac.

thanks what should I expect if I plug it in to our house vacuum 120 volt 20 amp circuit ?

Hm i suggest you reduce output to 6A. Maybe 8A..

Game On !

Did you use any profanity when describing how it did not work for you?

Did you use any profanity when describing how it did not work for you?

you can read the review I wrote in the screen shot verbatim, what I think offended them was a link to this forum, ha ha, can't have that, everyone knows the only website you will ever need is theirs

so I must say I am a little bit bumbed, I connected the EVTVDue board with an older style USB cable to my laptop, launched Saavy CAN which by they way is just an executable (pronounced: you don't have to install it you just double click a .exe file to open it up) quite brilliant really, as it means it's very portable, and nothing happened

So I launched Arduino IDE (the software program where you write code and run code) I made sure the right COM port was selected, I crossed my fingers and launched the serial monitor, then I typed "?" took a deep breath and hit enter, and as I suspected, nothing happened which confirms to me GVRET must not come pre installed on this card

that's the only way I know how to check what is on an Arduino board, if you have any suggestions I'm all ears

my opinion is that it would be a real value added feature if the board came with GVRET pre installed, now I don't know if that means they would need a couple flavors of the board like one for Linus, one for Apple, and one for Windows, but I think they could reach and satisfy an larger segment of the not so DIY EV conversion community, as I find Arduinoing a steady P.I.A.

let me know your thoughts

as I was saying Arduinoing is no fun there's errors every time, and here it is no different, so I am not trying to compile the GVRET code (pronounced: firmware) onto the EVTV Due board, and I am getting an error:

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Huh. I would've assumed it would be pre-programmed.

Have you told the Arduino IDE that you're compiling for the Due? (Tools, boards,... I think from memory)

Yes sir, and I even tried both the Native and the Arduino ports

so after a bit of an investigation (starting with the basics) here's what my laptop aka Device Manager sees the genuine Arduino Due as, as compared to what it sees the clone EVTVDue as: Bossa ???

so I tried searching our Wiki for "bossa" next and that yielded "no results matching the query."

Bossa is this https://www.shumatech.com/web/products/bossa, it means that the board is totally blank and just contains the Atmel (chip manufacturers) bootloader. The Arduino IDE should still work with this though.

I'll set mine up and see if I can reproduce (although I'm on Linux so it may behave differently)

BTW - I agree completely, the Arduino environment is a pet hate of mine, capable enough to try to do complex stuff with it but with none of the debug tools to figure out why it doesn't work!

thank you I appreciate that

Bad news, mine works fine. Erased it to blank and reprogrammed over the native port no problem.

Guessing it might be a Windows driver issue. Long shot but it might be worth trying it on a different PC USB port (it sometimes re-installs the USB driver)??

Can't believe it comes without the firmware on it It might not suit everyone but for people who are buying buying it (and paying the premium) for a complete, ready to go unit, it makes no sense at all!

Other option is to export the binary from Arduino studio (Sketch, export compiled binary) and then use the BOSSA programmer to program the board.

It looks like BOSSA is included with arduino, see here for more details on how to use it https://forum.arduino.cc/t/sam-ba-bossa ... n/176495/7

I concur 100%, those [ahem] saavy enuff to know their stuff can simply over write what's on the board when they get it if it doesn't suite their needs, and us newbs would have less headaches

first of all thank you all for your feedback and offering to help, the troubleshooting continues, here's what Arduino sees on the COM ports for the Due vs the EVTVDue aka Bossa (ie nothing)

great suggestion, so here is the error it gives me on my PC (the other one was my laptop)
