What new MCU do you want to work with?
« on: August 17, 2014, 12:44:46 PM »
We seem to be an Arduino/Raspberry Pi centric group. I know I'm wrong to suppose that, but that's how it appears.
So how many of you are using Beaglebone or something else? I'd love to see an nVidia Tegra/Jetson and the new Sharks Cove...


Let's make a list of MCUs and discuss our knowledge base regarding microcontrollers. There are some new players. So let's be thorough. Also, let's be scientific and not go all pop-culture on this thread.


Is anyone up for hosting a google doc on the subject?
What niches do you see any of these boards filling?


Here are some links to explore:

I've used FPGAs, a Beaglebone (pre-BBB), and one of the TI devboards (with touchscreen!). I own and have not used a couple of Launchpads. I turn to Arduino time after time for quick prototying and final projects, though.

Things I want to do:
  • Barebones AVRs like the ATTiny series using AVR C (4313, 2313, 85, 45)
  • mbed development board (there's a cheap one out for $13: https://mbed.org/blog/entry/mbed-enabled-Freescale-FRDM-KL25Z-board/)
  • Beaglebone Black
  • Spark Core (yes, its an arduino.. still)
  • Papilio FPGA
  • Parallax Propeller (we got dev boards awhile back, and the propeller 2 is coming out in december)
  • PIC
  • CC3000 / MSP430 Launchpad
Things I've done but haven't touched in awhile, and was never great at:

Okay, I have a Spark Core, too. :)

Spark here. Its got some great specific use cases.

I'd like to learn beaglebone enough to know when it is a better board than the Raspberry Pi.

I'd like to find a board with serious CPU when needed AND GPIO - an expensive Raspberry Pi more or less...but at the same time, still debian if possible to I don't have to relearn all the things.

And its silly - but I'm having fun with the littleBits Arduinoand will be ordering their cloud module for more giggles.

I've got an Arduino board that I've barely used and a Raspberry Pi (which I just picked up today). I also want to play with the Beagle family. 

I think the Parallela is interesting.   https://www.kickstarter.com/projects/adapteva/parallella-a-supercomputer-for-everyone?ref=nav_search
I don't have an application for it yet, but I want one.

I'm really interested in the abilities of the Cypress Semiconductor pSoc (programmable system on a chip) family of processors.  It is a mixed signal processor, ARM based, that gives you FPGA like ability to create functional blocks that handle analog AND digital signals in the chip.

Maybe we could do some organized hack nights where we just get together and figure these things out? Maybe do bulk orders?

I am using arduinos but plan to pick up a Rpie. I would like to do some avr programming direct to amtel but i haven't programmed assembly in a while.

We used to have micro controller Mondays which were very cool.

AVR,Z80,6800,6809,68000,8086


fixing arcade and pinball boards, i work with all kinds of cpu/mcu :)

I'm all about RPi (since the B+ has _real_ mounting holes now) mated to Arduberry because of the huge community (both RPi and Arduino).  Eventually I want to go 'distributed' with RPi with added simple can-bus daughter board hanging on GPIO header that talks to multitude of can-bus nodes of all flavors (mbed,pic,avr).

If you do can-bus, I want to learn more. Still intend to build an MCU-controlled automotive wiring harness...one of these days!

I can-do can-bus when i work w/ huge outfits w/ huge budgets (the last one i worked on was with EADS).  However, when I work in my own lab (low budget, cave-man tools) I have a lot of problems that I haven't sorted out yet.  The problems come at higher speeds (> 250kbps) and full bus arrangements (multiple nodes).  Since it's a 2 wire multidrop, reflections have to be handled exactly right.  After my current project I'll be concentrating on multiple node solutions to all things embedded so I'll hopefully find cheaper bus analyzers and such.  I'll also be fiddling w/ OBD-II a bunch so maybe we can collaborate.

Currently, I have a couple of RPi projects, but I've been basically an Atmel/Arduino guy lately.  In the past, I've done projects with PIC, BasicStamp (remember those?), RCA 1802, 6502, and 808X (early stuff, not x86).

6502's are still inexpensive and fairly easy to work with -- for people who want to program in solder, they're easy to build with.  PICs have a wide variety of I/O types, and if you can put up with their paged memory scheme, are quite capable.

The main reason for the dominance of Atmel stuff for small controllers is the simple toolchain to get started.  Perhaps we need to document toolchains to use the alternatives?
