Thank you a lot!

I appreciate very much your work. I know how difficult it is to write libraries that match the needs of everybody. I will give a good use of this info!

I grow up in engineering through pages and pages of datasheets (when you had to get them in paper, long long time ago...) so although it is not the Arduino Spirit, sometimes I prefer go to a low level...

In any case THANK YOU!!!!! You guys have my full respect!

Hello friends

I've been programming for a while with the API and there are some questions that I don't get very well.

These are my questions for the gurus:

1) I wasn't able to find the structure of "can_mb_conf_t" and the correspondence of the different elements with the CAN Register mapping (Section 41.9 of SAM3XA of Atmel documentation) so I get a little lost...
2) I also would appreciate a list with all defined parameters.

Thats all by this time.

Thank you a lot!!!

Just starting to try out!

Thanks!

Hi guys!

I've been trying out the CAN API and it works all right.

My sincere congrats to all developers. You have done an excellent work!

I have been testing the CAN api and everything works smooth at all speeds up to 1Mbps.

Although I have some comments:

The Can mailbox config structure "can_mb_conf_t" contains only two possible data, datah and datal. Is there any direct way to address individual bytes (B0 - B7) of the CAN message? Obviously the DLC param should has to be correctly set.

I'm using Line Driver SN65HVD232 (without any kind of low power mode, or anytingh else than pure CAN line driving) and I think that it is a little bit unconfortable to start up the transceiver as SSN65HVD234_Data can0_transceiver; instead of just using a generic CAN pin enable. Other options could also be using any 3V-5V line transceiver and using after any standard 5V Can driver.


Thank you again folks!

Lufe - I'm working to build a better "industrial protocol" arduino board, integrating modbus / rs232 (12v) and CAN and 2x Due chips. I just saw Palliser's ethernet addin and am debating adding that in by exposing those pins off of the dues for future expansion for profinet if possible. Is this something you would be interest in collaborating in?

Zabaat (and everybody else too, of course)

I'm developing for several projects I'm involved in a multifunctional shield with RS485, TTL UART, CAN BUS, TTL digital GPIO, discrete open-ground outputs, relay module and Analog Input port, for the MEGA board.
CAN BUS is based on MCP2515 IC, but I would absolutely prefer to use an internal CAN peripheral, therefore I'm following very closely the evolution of the Due board. Testings of this board will start middle February and if everything goes ok, I'll be presenting it soon.

As I told in my introduction, I'm not an Arduino expert nor a programmer guru, but I really would like to collaborate with any interesting project like the one you are presenting.

Estimado Palliser
I'm looking forward to test as soon as possible this CAN library. Being able to have direct access to CAN from a CortexM3 processor... smiley-yell this sounds sooooo good!!!
I'll get today all my 3.3V CAN transceivers, I'll mount them tomorrow or Monday and I will have my DUE CAN test bench available for you!

Cheers

I'm in the same position as Zabaat.

I'll build the Pseude shield ASAP and post pics. Maybe I try out another HW solution from the IC I have right here. I would also like to be collaborating with a beta release and feedback you directly.

Cheers

Hi everybody!

I`m quite new to the Arduino world, but not to the uC world. I'd like to collaborate as much as possible with the development of the CAN API for the Arduino DUE. I actually have several DUE and other Arduino boards (with the necessary shields) and USB CAN interfaces, as well as other applications that are extensively using CAN BUS.

I'm very sorry of not having been able to start collaborating with you earlier, but I really would like to help as much as possible in any task you give me.

Cheers!
