Hello that_kid. I hope your foot is doing better. Here another picture of my second DIY pseudo CAN shield and a brief comparison between the two shields:SHIELD ADVANTAGE DISADVANTAGE #1 Compact Prone to hot spots (soldering) #2 Easy-to-assemble Bulky and messy
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!Lufe
zabaat,What you're saying is partly true, until the new CAN library is published. The Atmel engineer that developed a prior CAN API for the SAM3X8H, is supporting Arduino with this CAN interface for Due. Once the library is on github, everyone should start to test/discuss/contribute. And I say partly because at this very moment people in this forum could be contributing, let's say, with the design of the shield. Electric schematics have been published here. I have also shown a couple of my shield approaches. What I would like to hear in this post is: My pseudo CAN shield is ready. Here a picture of it, but I have yet to see any of them here. Does that really matter? Yes, because otherwise, you can't do any test or discuss or contribute just with the sketch or the classes. Am I right?
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.CheersLufe
Hola Lufe.Your CAN experience will surely be very useful. As I mentioned in my first CAN post, my humble role is to channel the efforts to let the CAN API be completed. So far, I must say, it has been more a behind-the-forum work between Arduino, Atmel and me. Tests are in progress; the CAN library is working using the IDE directly (no makefile) and we are close.From all of this, we have learned a big lesson: DO NOT (I repeat) DO NOT try to build something from Atmel Studio ASF and introduce it into Arduino. Both software architectures are entirely different and it shall be a pain to remove unneeded references. This experience is helping us to understand better how to create a Due library. The updated libsam will be solid ground for future developments for Due. Saludos!
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?
