Ardunino on SAML21?

[mrpackethead]

Does anyone know if the Ardunio environment has been ported to the SAML21 processor family?

The SAMD21 did, But I don't have success in writing this $%^% any programs,

The SAML21 seems "more different" from a SAMD21 than you'd expect from the part numbering.  (as is the SAMC21.  Curse you Atmel and your part numbering!)(although with a quick glance it looks like the only thing that would affect the Arduino "core" is the ADC differences?)

Nopes there's no Arduino bootloader designed for SAML21, why don't you work on real arduino ?

These guys offer an "Arduino compatible bootloader" on a board which supports the various SAMx21 flavors:

@jackthomson41,
I noticed a burst of posts from you on multiple threads, although you don't seem to have much to add to any of the topics. Are you working towards a high post count in preparation for posting commercials and spam, or just because it feels so good?

How much work is involved with porting ardunio to a new platform board?  ( I've never really used ardunio except for a few hours of messing with it. ). I'm working with a newish Chip from microchip ( ATSAMR34 ) which is a a SamL21 plus a radio chip.    While i'm quite happy working with the development environment i'm using, i do appreciate that its much tougher than ardunio.. It does look like it can be ported to a L21...

Well, that depends.  It's generally pretty easy to get a compile and some of the basics working.  And then there's this LONG tail of getting all the other (harder) things working, with (if you "release") a never ending list of complaints that some relatively obscure library doesn't work...  (for example, there's still a fair amount of complaint that Arduino Due didn't get all of the attention that it deserved, and the stuff that Adafruit customers are discovering doesn't quite work on SAMD51 keeps getting added to.)

Arduino is frequently easier because you can just go out and find code that someone else has written that will be pretty close to what you want to do.  That won't be true, if you're using your own core for some outlying chip, and mostly working on some obscure peripheral...
That said, I find that the Arduino core is "not awful" in terms of what it "abstracts."
