Hi,

Me again.

Just in case you are going to Embedded World 2013 in Nuremberg, Germany, next week (26th - 28th Feb), feel free to drop by the Atmel stand  in Hall 5, Stand 5-311, and ask for Stuart Cording.

I'll have the board with me and will be able to demo it.

Hope to see you there! Best regards, Stuart

Hi James,

Yes, this is the intention.

Since I don't have an automotive qualified 8-bit AVR with USB, I intend to implement the USB/UART interface so that it can be broken off, thus leaving the remaining board as 100% auto qualified. The USB/UART interface isn't always needed in all applications.

Does that sound OK to you? Alternative would be an AVR32, but I want to avoid to much unnecessary components on the board when doing the EMC testing. Seems pointless to me adding huge complexity and time into fixing potential EMC issues in the USB/USART section of the design just to pass standard EMC tests.

Hope to hear from you soon.

Hi,

Thanks for the link - that is an interesting concept with the Rugged design.

The concept with Allegro is not to make all of the AVR pins automotive capable, rather make the board automotive capable for use in the car.

The power supply will support direct connection to the 12V connection in the car, whilst being able to withstand peaks of up to ~40V which occur when the battery is charging or as a result of starting the engine. On top, with CAN and LIN the board will be capable of commuicating with in-car networks.

I am hoping that the CAN and LIN busses will also be of interest for those who want to network Arduinos to exchange data between them outside of the automotive environment, and who require something simpler than ethernet.

BR, Stuart

Brilliant! Thanks very much. Couldn't see the wood for the trees :o)

Dear All,

Another project of mine is the "Allegro" project. This is essentially an Arduino "Uno" featuring an automotive grade ATmega64C1 featuring LIN and CAN interfaces.

In addition, the plan is to include an automotive grade supply circuit and LIN transceiver. The CAN interface would be supported via a shield.

The project is hosted here:

If you are interested or want to know more, just drop me a line.

Thanks and best regards, Stuart
6  Using Arduino / Programming Questions / Where does "Serial" get defined in the Arduino environment on: February 06, 2013, 02:33:08 pm
Dear All,

I am currently designing a library for Arduino and I am using the the "HardwareSerial" class as the model for my library.

Despite having searched through all the source code, I am still at a loss as to how "Serial" gets defined.

In the "HardwareSerial.h" there is:

extern HardwareSerial Serial;

This means, as far as I remember, that "Serial" gets defined elsewhere. I just can't find where.

Looking at this another way, why can I write in my Arduino setup() function:

Serial.begin(115200);

without first having to have written:

HardwareSerial Serial;

in my sketch?

Many thanks in advance for any support on this! Stuart
