Fred 453 Posted March 27, 2012 Share Posted March 27, 2012 It seems TI have just produced an audio / capacitive touch booster pack. On special at $30 for a while, then up to $35. Ideal if you want to make your own iPod I suppose. nuetron 1 Quote Link to post Share on other sites

SugarAddict 227 Posted March 27, 2012 Share Posted March 27, 2012 Ordered. Edit: And I see why I'll never use these chips... they ONLY come in BGA. Quote Link to post Share on other sites
nuetron 64 Posted March 28, 2012 Share Posted March 28, 2012 BGA? Is that the surface-mount package with the inaccessible grid pads? Quote Link to post Share on other sites
GeekDoc 226 Posted March 28, 2012 Share Posted March 28, 2012 BGA: Ball Grid Array You have to use solder balls (of the right size) arranged in a grid to solder to the contacts on the chip. See wikipedia entry. nuetron 1 Quote Link to post Share on other sites
zeke 693 Posted March 28, 2012 Share Posted March 28, 2012 Acccchhh! I've been soldering BGA's with a paint stripping heat gun ever since you were a weeeeee lad! accent> BGA's ain't no big thing. Just need to lay out a PCB that has tons of test points on it. The other situation where BGA's are untrustworthy are high vibration environments. It the PCB thickness isn't generous then the BGA could self-disassemble. Quote Link to post Share on other sites

It the PCB thickness isn't generous then the BGA could self-disassemble. And high heat applications... Like Laptops or Video Cards (or video cards in laptops). And you really need a xray machine to see if the solder properly melted. Quote Link to post Share on other sites
TomKraut 17 Posted March 28, 2012 Share Posted March 28, 2012 I find this booster pack veeeery strange. You have a powerful DSP which does nothing but MP3 en-/decoding and thus should have a lot of spare processing power. Then you connect a MSP430 for the UI, which tells the DSP what to do, going so far that the OLED is connected to the DSP, but you control it's contents via the MSP... Overall, this is a very complicated design which has no relevancy in real life. I guess this might be a fun thing to play with, but a multi processor design where none is needed is always a bad idea. Still: if it had at least an integrated XDS100 emulator, this would be a very cool deal to get started with C55x DSPs. But since the schematics aren't online yet, I'm not even sure if you could connect an external emulator to the DSP. Cheers TomKraut Quote Link to post Share on other sites

But as I never worked with the C5000s, I thought that just maybe there might be a valid reason for doing this. The only thing the MSP430 does, which the DSP might not do as easily is the capacitive touch. This kinda reminds me that I need to get some time to play with the C5000s (and of course some HW) :-) Quote Link to post Share on other sites

Cheers TomKraut Demonstrates Implementation in existing projects without needing to port over code? Demonstrates availability for hobbyists who wouldn't be able to work with the more complicated aspects of a DSP like bootloading, or who don't have access to more expensive development tools? gordon 1 Quote Link to post Share on other sites

chibiace 46 Posted March 31, 2012 Share Posted March 31, 2012 If your in the states you can do their survey for a chance to win one of these boosterpacks. Quote Link to post Share on other sites
cubeberg 540 Posted April 2, 2012 Share Posted April 2, 2012 If your in the states you can do their survey for a chance to win one of these boosterpacks. FYI - the survey link is available on this page Thanks for the head's up on that! bluehash 1 Quote Link to post Share on other sites
TomKraut 17 Posted April 3, 2012 Share Posted April 3, 2012 Schematics are online now. The JTAG port is completely exposed on a non populated header (easily fixed ;-) ), so this has suddenly become veeery interesting One could either connect a LP + XDS100v2 emulator board, or one could build a board which supplies power to the booster pack and has an integrated XDS100 (but no MSP430).
