No, I just spent a while looking and I didn't see one.
Very strange. The whole Arduino thing is all about open source, so it's bizarre to
see an Arduino spinoff that isn't open. It's permitted, since the Arduino license
isn't GPL, but it's surprising.
I can't see much reason to do business with a closed Arduino clone purveyor when good
open ones are readily available from Adafruit and many others.
I looked a bit at that Weact thing but got lost
in the fulminating about "pirated" copies. Seriously? Open source designs are
meant to be copied; "pirated" is a nonsensical term. Low quality copies, that
would be a valid complaint. (The use of leaded solder, all things equal, increases
quality rather than reducing it, by the way.)
I really don't think that WeAct say that it is "Open Source". Do you see a
license saying it is Open Source? ...
Thanks, I'll check that out, it may be needed.
The ARM chips used in the Adafruit boards
I've used have on-chip flash so I'd assume that runs quickly, but I'll have to
try to find out.
No, It also has wait states. But the TCM can be used as a cache as
far as I can see from a quick check. I am by no means an expert on this. I just had a
quick look right now. (https://github.com/adafruit/ArduinoCore-samd/issues/37) ...
If you have further questions feel free to ask. Would be nice to add DDCMP support as
well! Then perhaps I could try those M8203 / M8207 boards I have sitting here.
Thanks, will keep that in mind. What sort of connection and signaling do your DMR boards
use?
