[TriEmbed] Learning Curve

[pete@soper.us]

I've been playing w mbed for a few hours here and there. I'm having fun with the ST Nucleo F401RE dev board ($10.30, 84mhz, 96kb ram, 384kb flash, "arduino compatible" shield headers, arm M4F lqfp64 chip under $5).  Not at all clear yet how much the ide and library infrastructure can be trusted. ARM (corporation leading the efgort, creators of major tool chain pieces, etc) certainly know what they're doing, but at least some platform code effectively crowd-sourced and QA requirements for put backs to the tree seem lacking. Gene Kahn and I have seen one episode of "what built yesterday no longer builds today." But with an N of 1... My guess is that if you use an mbed-compatible board that has a lot of users stuff will tend to be stable as support for the board's features is built out. -Pete

The world of embedded microcontrollers has seen some dramatic growth (from my perspective) and it is tough to figure out where to invest my learning time & energy.  

I have followed this path so far:
1) Arduino
2) Raspberry Pi
3) Spark Core
4) Intel Edison (just using it as a Linux box so far)
5) TI SensorTag
and played a bit with the NXP LPC1768 running mbed (http://mbed.org/)

Mostly I have been simply playing with the various "developer kits" where my mission is on detection and connection - trying to understand what can be sensed and how to get the data back to the cloud.

How do you all feel about mbed? Is that worthy of expending dozens/hundreds of hours of learning time? And if so, which of the various ARM/mbed-based hardware vendors are interesting to you?
