Has anyone tried getting their Maple to talk to a CAN bus?

under the Design Support tab.
I couldn't see any documents with CAN in their title!-(It might be worth asking at ST Micros STM32F forum
https://my.st.com/public/STe2ecommunities/mcu/Lists/ARM%20CortexM3%20STM32/AllItems.aspx
because I would believe their is something somewhere, but 'can bus' isn't searching. It just gives up!Posted 5 years ago # -
as i said, check the reference manual. ;)
there is a 20 page discussion of the CAN there, and it looks to be pretty thorough.

The OP asked
Has anyone tried getting their Maple to talk to a CAN bus?
As the answer was evidently no, I thought it helpful to suggest a place where there may be someone who had implemented CAN on an STM32F
Further, a friend said recently that it took a bit more care to get CAN working nicely than the manuals might suggest; he's done it a couple of times for his undergraduates, so I take note of his opinions.
So I wondered if ST had written an Application note.
They have Application notes for using DMA, ADC's, DAC's, Internal clock, clock/calendar, timers, USB, I2C, etc.
All of those are also in the reference manual.I do not conclude anything from the lack of an application note, but I had hoped it might help to mention that I had failed to see it there.

the standard peripheral library has 3 examples (titled DualCAN, Loopback, and Networking), but i'm having trouble locating it online.
st's website redesign has been such a catastrophic failure. it used to be hard enough to find things, and now all of my bookmarks are torched, along with google's (and even suppliers like digikey's) links..

ModeratorThere is an Application note listed at:
http://www.st.com/stonline/stappl/resourceSelector/app?page=resourceSelector&doctype=APPLICATION_NOTE&SubClassID=1169AN3154 about using CAN to boot.
But the web site is so F#@ked up, I can't get a link, or even copy and paste the title.{begin rant
I suspect, but have no information, that ST have employed or promoted some new marketing 'talent'. The trouble with marketing 'talent' is they have a need to be seen to change things. The problem with mediocre marketing 'talent' is they don't really understand how to improve things, because they don't, or can't, figure out what is critical. I suspect that may have happened at ST.IMHO, you'd have to be pretty crass to change a web site so that it breaks accessibility.
I think that is shameful.
IMHO, you'd need to be incompetent or stupid to change an OEM product companies web site so that the OEM product documents your customers need are hard to get.
IMHO, you'd be commercially suicidal to stick with it after you'd discovered the site is too hard to use, preventing customers from using your OEM products in their new products, so they can't buy your OEM product in quantity.Frankly, if ST don't fix the web site soon, they will start losing business; may have already started, who knows. When I see a technology company lose track of its mission for an extended period, I assume they are going to kill themselves unless rescued.
I did write in the forum
Better to fire the marketeer than alienate your user base :-)
(IMHO opinion, a marketeer who is responsible for breaking any mission critical web site is going to be out of a job eventually anyway, it is simply a question of whether the company is still viable at that point, or not. :-(
I hope that helped.
