Example UART in uartdmx plugin readme is wrong?

[peternewman]

Hi @richardash1981

Looking at some of the discussion in :
https://groups.google.com/forum/#!topic/open-lighting/myWi-K570Rc

It seems the example device in the uartdmx plugin may be wrong, as it's /dev/ttyACM0, whereas it appears it should be /dev/ttyAMA0.

It looks like this appeared with the plugin in this PR:
#385

After my (rather terse comment) in this commit:
39b4bf5#r12026667

This also contradicts your own instructions:

Have I missed something, or should this really be /dev/ttyAMA0?

I've built the extension circuit by @richardash1981 to use the Native UART plugin with the Raspberry Pi B+ and did indeed have to change the default setting to /dev/ttyAMA0.

When you say change the default setting @FloEdelmann I assume you just mean what you copied from the readme? I don't believe we pre-populate that field on that plugin.

Terry seems to confirm this here too:

@peternewman Correct, that's what I meant.

This may also be /dev/serial0 in later Pi software...

Also confirmed in the blog post here: http://eastertrail.blogspot.com/2014/04/command-and-control-ii.html
