[TriEmbed] TriEmbed Digest, Vol 35, Issue 3

>From what I have read, this might not be a struggle worth having. Here's
one article:
http://www.shaftnet.org/users/pizza/archives/2013/09/11/okay_freescale_i_give_up/

I have one of these too from the freeRTOS class and I don't see myself
keeping a windows dev environment around just for it (even if it is just
a virtual machine). Do you want to do freeRTOS development on it or just
straight c/c++? If I were doing freeRTOS I'd probably buy the FreeRTOS
NXP LPCXpresso LPC1769, since there's a tutorial PDF specifically for
it. 

If you don't care about that, maybe STM32F407G is better? Sounds like
STM tools and libraries are poor but people have figured things out on
the open-source side. For $19 you get way more flash and RAM, and when
you tire of it you can turn it into an vector arcade board with XY mode
on an oscilloscope: http://tubetime.us/?p=291
