Since I have been looking for a microcontroller platform that I can settle in to for advanced and relatively high performance operation, I have been collecting and testing different things. PIC,Arduino,Micromite,ARM Basic ...

I just received a Texas Instruments "Launchpad" for the MSP430F5529. This is a 16-Bit, 80 pin microcontroller with 128K flash and 8K ram (and other stuff). The micro can operate at up to 25Mhz fron an internal clock. Not a speed demon but pretty good.

So I loaded the drivers and plugged it in to the USB port and after everything was detected, it had loaded a virtual "Drive F:" on my PC, with 85K of space. Pretty cool. ( I wondered by the PC was dinging so much)

Besides TI's (Eclipse) Code Studio, you can also use Energia, which is a modified Arduino IDE for TI MSP. Code studio has a 16K code limit with the built in "C" but if you like GCC it can be installed as a plugin with no limits.

The board has an integrated programmer and debugger.

It only costs about $13.00 US .... Amazing little development board.

Iv'e already evaluated Arduino and ChipKit as well various PICS in MPIDE C/ASM and some of the free Basics (I like Great Cow) , so I guess I'll dig in to this one and find out what's good and what's bad.

But for $13.00? I paid that much for a 28 Pin Picaxe chip alone.

About the same price as the ST NUCLEO and other STM32F boards, but the ST boards tend to have at least double the RAM and 2x or 3x the speed. The slightly more expensive STM32 boards have 1M flash, 192K SRAM and run at 168MHz, then the next are bigger still and include a display.

As you're in USA some of the ST boards are (or were) free!

Being ARM cores they are widely supported by free & non-free tools.

Guys, both of you, links please! And images if possible. Try talking with the examples on the table (John, that is a bad habbit of you

).

A question for both, those chips are solderable by human beings?

Goey, I also try to decide which 16bit family to chose: ATXmega, dsPIC33F/PIC24F, MSP430.

1. For info see ST web site.

2. For prices see any of digikey, element14/farnell, mouser or ebay etc.

3. Or use google

I figured people know the above!!

There are a LOT of very cheap & powerful STM32 boards, far too many to start filling pages on here when a simple search works so well.

But just for you... went to mouser site, put NUCLEO in search box, chose this
roughly $10, 512K flash, 96K RAM, 84MHz

I also like this
about $25, 2MB flash, 256K SRAM, 8MB SDRAM, colour LCD, up to 180MHz

and this
only $16, 1MB flash, 192K SRAM, 168MHz

I have no interest at all in soldering tiny chips especially when complete boards are very cheap so no idea as to the soldering. It depends on your skills & tools e.g. whether you are WhiteWizzard...

If all you have is a traditional soldering iron & no magnifying glass then many modern chips are out of range except if you buy a ready built board. No big deal, just buy.

Thanks!

Yes, they do (at least, this is what I believe regarding me), but makes your posts more prettier and interesting and you a little warmer and approachable.

Didn't knew Nucleo means Arduino socket...

Pretty amazing. Things have come a long way in just a few years.

Consider that on a commercial project that I was involved with in 2006, the company paid over $6,000 for debugging tools/emulators/ programmers for ST7 8-bit stuff. I still have all of it here in a closet. One complete package is still new-in-the-box but will probably get thrown out soon as I have no use for it and I doubt it has much value.

One of the most powerful Arm Launchpad Boards for less than $20 directly from TI, that can be programmed with Energia (Arduino environment).

Launchpad board details

Don't forget the great little DIP 16bit MSP430. Very versatile general purpose controller with 62.5Ns Instruction cycle and ULTRA low power consumption for battery operation. Programmable with extremely easy Energia

Maybe worth putting on ebay, even with 0.99 start (and enough postage to be viable) as someone may want that stuff. A pity to discard it.

Too late for Ebay,

I just gave it all away yesterday to a young EE here in the US from Bulgaria. He also got about 100 ST7 Microprocessors, a Xylinx Extreme DSP Development Kit, a Renesas RX62N Development Kit, a Chipkit UN032 and an old (but working perfectly) Hitachi 200Mhz Scope.

I did have him give me $10 for the scope. (Was a matter of principle)

Brilliant! Much better than discarding them.
