  1. Hmmm, because of the weird Arduino pin spacing the shields don't fit mechanically and the voltage does not match ( 5V <-> 3.3V ). But it can be done though, it's just no plug and play.

    Will a adapter boosterPack work? However I'm not sure how ADC voltages would be made compatible. I find Arduino shields a bit expensive while the msp430 boosterPacks so far are pretty low priced.

  2. OK, not necessarily the best of thread titles, but at least it's honest.

     

    I've ordered the new Stellaris Launchpad. I'd like to know what to expect, what it can do, but in plain English, please. I'm a PC hardware person with a little more than enough electronics knowledge to be dangerous, but absolutely no microcontroller experience -- and almost no *meaningful* programming experience.

     

    What am I wanting to do? Well, I'd like to see if I could build a mini Linux box with it. I'm thinking a few SPI (or I2C if I can find 'em) SRAM chips totaling 128mb and connections to an SD card for memory and storage... I've not worked out the video yet, but it will almost certainly be fairly primitive. I'll be rolling my own Linux almost for sure, but I think I can handle it.

     

    Er... yes, I do want SRAM and not SDRAM -- SDRAM requires that dastardly refresh signal, which would eat up a small amount of CPU power. I know I'm going to need every cycle I can get, so SRAM it is.

     

    I certainly stand to learn a lot in the process of building this thing, if I somehow gather the patience to stick with it ;)

     

    OK... now hack me to bits :wacko:

     

    I made a post here earlier in the project section Linux on Stellaris M3 - Is this real? which I found on youtube. I have no idea how it's being done. If you think about it, the Stellaris Launchpad is controlled by an LM4F chip that does not support external SRAM( EPI interface) like the other Stellaris chips, so it's a bit difficult.

     

    The Stellaris is great for controlling actuators or running displays. It was certainly not meant for running Linux. There are other architectures like the broadcom on the RaspberryPi or the beagle board which are designed for it.

     

    Hope this helps and does not let you down in anyway.

  3. Just found this on youtube. 25m range through walls.

     

    This demo showcases streaming music from a Bluetooth enabled smart phone to a CC256x radio using the A2DP profile. The host processor is a LM3S9D96 ARM Cortex-M3 that is hosting the A2DP demo available with the A2DP evaluation kit featuring Bluetopia from StoneStreet One. Using a 3.5mm auxillary to composite audio cable and the PurePath Wireless Audio evaluation kit, the master CC8530 streams gapless music to four CC8530 slaves which is being output through four speakers. Here are the links to each evaluation kit. All of the evaluation kits used in this demo are from Texas Instruments.

     

  4. I'm running an extremely low budget, i.e. no money available for projects or buying new dev. boards. i am forced to use what i have, which is an STM32F0-Discovery i got free from ST. so the change to stellaris only is an unwelcome one.

    Their initial price is $5. It's not much, but I can see it hurts sometimes. However you will not regret it :)
