Also, if you want people to help, put this stuff in a Git repo! Anything else is just unprofessional, really.

This board will be sent for production tomorrow... if nobody has concerns

You need to add the LOAD circuit back to Port A6 or else you won't be able to load firmware. At a minimum you need a 1k ohm resistor between Port A6 and the LOAD jumper and a 2.4k ohm resistor from the LOAD jumper to Vcc. The LOAD jumper is used by jumpering it to ground to boot the microprocessor into the serial monitor mode so that the loader software on your PC can work.

See my attachment for the circuit.

This is exactly why you should pay attention to reference design schematics such as jaguar and ravage.

You leave out critical stuff like the load jumper circuit and you are on your own and in for a world of frustration and dirty hardware hacks.

I guess to summarise:

1 Use Git.
2 Take your time/Don't rush
3 Study/check ravage/jaguar extensively

Don't take offense to the above posts. They may be harsh, but it's for your own good.

Quick Update !
Board is running.
I have tested ADC´s, Injectors and fuel pump with 0.2.0-SNAPSHOT from DEUCE.
For test purpose have inserted and removed the Board about 50 times. It feels pretty rigid and solid.
I didn't buy the special bended connector, just took the standard ones and bended them..

Thanks everyone who gave me constructive Feedback

now will mess around with firmware ...
Yes BRV is wrong ..

Cool :-) Now that you intend to do something with it, please post a thread about your vehicle/application in the users' rides section and detail your setup there. If you don't do that, I can't tell you how to proceed, and if you try to proceed on your own, you may will have issues.

Fred suggested to upload the files on a repository.
So now it is on Github.

Good stuff! :-) It could do with a license, may I suggest copying what Andy has done with Jaguar for that. viewtopic.php?f=67&t=2394

How many did you have made? AKA Do I get a souvenir? :-)
