Stellaris LaunchPad

Recommended Posts

Regarding to subject, I have a question which I hope to be answered. What exactly does the highlighted text mean? Pic below:

This is from page: http://www.ti.com/ww/en/launchpad/stellaris_head.html?DCMP=stellaris-launchpad&HQS=stellaris-launchpad-b

 

Does this mean that the Code Composer Studio doesn't have the size-limitation (16k?) when using it with stellaris-launchpad so that all bytes of the 256 KB can be programmed if needed? I tried to search for more information but didn't find anything. Please help :smile:

 

http://processors.wiki.ti.com/index.php/Licensing_-_CCS and http://processors.wiki.ti.com/index.php/Stellaris_support_in_CCS indicates no limit, on the bundled download (Stellaris Ware + CCS). The 16kb limit still exists for the msp430 though.

I've been interested in this launchpad however, when does the LM4F chip series actually get released? Kinda stinks to have the dev board before the chip release. Normally I use the msp430 launchpad to prototype a project then I build it with a all SMT solution. Can't really do that with the ARM launchpad if the LM4F series isn't out yet.

I was going to say, just use one of the Cortex-M3 Stellaris chips, but it looks like they are dumping the old line or something.  It would be silly to buy a LM4F series when you are not actually using the M4 extensions.  Unfortunately you can't find the Cortex M3 parts on the TI website unless you search for specific part numbers.

 

Anybody else know about this?  I couldn't find this page without backtracking from a search on a part number I knew.  If they haven't already dumped them it looks like they are hiding them real well.

Hi Username!

 

I don't know where are you looking at but I can definately see some LM4F-series MCUs which are active from here: http://www.ti.com/lsds/ti/microcontroller/arm_stellaris/m4f_series/products.page

 

I have understood that any LM4F-mcu can be debugged and programmed through the launchpad.

 

At this moment these are are active:

 

LM4F230H5QR - Stellaris Microcontroller
LM4F231H5QR - Stellaris Microcontroller
LM4F232E5QC - Stellaris Microcontroller
LM4F232H5BB - Stellaris Microcontroller
LM4F232H5QC - Stellaris Microcontroller
LM4F232H5QD - Stellaris Microcontroller

 

All the other are in 'preview' state. I have a feeling that all of these 'preview's are set to active any day or week now.

 

Just my two cents :)

They might be 'active' but try to find a place to purchase them. Noone has a stock of these, which probably means that you have to order huge quantities to get your hands on more than one or two sample units.

But it is only a matter of time before distributers have them available, I guess :smile:.

Nice, I saw some of those LM4F23*s on digikey. However, they were out of stock and over 10 usd+ per qty 1. Kinda exspensive for a hobby micro. I'm hoping the LM4F120s will switch from preview to active somewhat soon and hopefully be alot cheaper than the LM4F23*s but perhaps i'm getting my hopes up. 6 dollarish range would be nice
