  1. It's the combined (and perfectly aligned) drilling and cutting out that tempted me in the direction of milled PCBs rather than etched. Nice and easy to produce a PCB in any shape you like. This is the PCB I milled for my updated MSP430-based PeeLight. It's nothing too complicated - just some simple through hole stuff. I have done some SOIC too.
  2. You know we're right and you're all wrong.
  3. I think dellwoodbu sums it up pretty well. The insight into the processing is interesting, but I'm sure the LX4F A3 has had a fair amount of testing at TI and is quite up to the job for us hobbyists. Think of it as a "release candidate" that passed testing and was used in production. I don't know about you lot but I wasn't planning on building anything safety critical with my LaunchPad. If anyone wants to send theirs back then I'd think TI would probably accept it, but do you really want to?
  4. They're only free in the US and Canada. Pretty cheap elsewhere though. A better place for ARM stuff (although mostly TI ARM obviously) is Stellarisiti.
  5. With the full version of CCS (which I got during one of TI's offers) it seems to work fine with both MSP430 and Stellaris. I know that doesn't help you much though. Sorry.
  6. CCS 5.3 is now available again - a slightly later build with a bug fixed.
  7. I thought it may amuse some of you to find out one of the more unusual places that a lucky MSP430 may end up... in one of these vibrators! :!!!: http://www.amazon.com/LELO-Lyla-Cerise-Wireless-Remote/dp/B005HRCL5S You'll find the details of a hack (that unfortunately replaced the MSP430 in the remote with an Arduino) here. http://hackaday.com/2012/11/25/making-a-touchless-vibrator-with-reverse-engineering/
  8. Surely you can find a few posts that you can make a constructive comment on? In fact asking that question got you one post nearer your 5.
  9. Maybe that's why they were only $5! For $12 you get the bugs fixed.
  10. I've not done much with the MSP430 lately and what I have done it's really up to much (and is very similar to my previous PeeLight project). However, if this meets the requirements then I'll make up the numbers... http://www.instructables.com/id/Motion-sensing-Lego-figure-nightlight/
  11. I've got an unused EXP430FR5739 I said I'd donate to the next PoTM but it looks like you already have one. I've save it for the next one...
  12. This project using 7400 logic chips for RFID might be helpful. http://dangerousprototypes.com/2012/10/19/7400-competition-entry-rf74xxid-a-passive-rfid-tag-from-7400-discrete-logic/
  13. I'm intending to run my Launchpad from a LiPo so Philipp's tip will be really helpful. I've actually go a 3S (11.1V) battery to power some stepper drivers and intend to "steal" 3.7V from the connector used for balance charging. I figure as the Launchpad will be drawing minimal current compared to the motors that this should be OK. If anyone feels like shouting "NO! Don't do it." then now would be a good time...
  14. Excellent. I noticed last night that Mouser had them. My local resellers don't have stock yet but I'm sure it'll be very soon. I will probably order a couple today.
  15. True, but the STM32F3 discovery was announced months ago and still isn't available. I was excited to see the Launchpad was still discounted on Farnell's mobile site (in the UK at least). Unfortunately you're taken to the desktop site to place an order and there's it's full price. I wish I'd order more than out at the start now, but didn't want to be greedy.
  16. For Stellaris chips is there any advantage of this over half a Stellaris LaunchPad?
  17. I wasn't suggesting using StellarisWare on other processors. I was just wondering about using CMSIS on the Stellaris. I theory that should make your code portable to ARM processors from other manufacturers. Whilst few of us will need to directly shift a piece of code, what might be more valuable is that the portability of your experience and knowledge.
  18. My current project is a balance bot using the Stellaris LaunchPad but there's a chance that once the STM32F3 Discovery is available it might be a better fit due to the onboard accelerometer and gyro. Then I remembered that the CMSIS library is supposed to be ARM's recommended hardware abstraction layer. Should we be using that on the Stellaris rather than StellarisWare? StellarisWare does seem nice to use and to be honest most of us are unlikely to be writing code that need to be portable but I thought I'd ask what people thought. I downloaded the Stellaris CMSIS headers from http://ww
  19. Attached is my Eagle Library for the Stellaris LaunchPad. It's my first attempt at creating an Eagle library so any advice would be gratefully received, but go easy on me! It was created in Eagle 6.2 so may not be compatible with earlier versions. It's heavily based on Gordon's MSP430 booster pack library from 43oh - http://forum.43oh.co...gle-footprints/ I intend to use to for mounting the launchpad on a larger PCB using the female header on the bottom but it should be OK for booster packs too. I've not used it on a board yet so there's a reasonable chance I've made a mistake somewhere an
  20. Definitely a good idea, although personally I'd need a bit more time to get something worthwhile finished.
  21. I'm going to have to knock up an Eagle part for my current project (unless someone knows of one already). I just found a MSP430 Launchpad one over on 43oh, so I'll base my Stellaris one on that. http://forum.43oh.com/topic/1243-lp-booster-pack-eagle-footprints/
  22. This is standard TI stuff, but I just stumbled across this today and hadn't heard anyone else mention it. I thought I'd share in case anyone found it useful. It's a tool to help you set up your peripherals and ensure you don't have any pin clashes. I used to find this a pain on the MSP430 (but never actually got around to trying Grace). So far the example code seem to have been enough to get me configuring things OK, but it looks useful of you've got a lot going on. You'll find a better explanation, a video and a download at this link. http://www.ti.com/tool/lm4f_pinmux
