gatesphere 45 Posted December 10, 2010 Share Posted December 10, 2010 Hello everyone. I did some mucking about in my include directory after the recent CCSv4 update and found some interesting new headers... On my blog I've done a writeup on what I was able to extract from those headers. http://blog.suspended-chord.info/?c=29 I hope you all find this informative. Oh, and thanks, TI, for letting me do some detective work! EDIT: Now updated with flash size information. Check it out. NatureTM and bluehash 2 Quote Link to post Share on other sites
juani_c 66 Posted December 10, 2010 Share Posted December 10, 2010 I was expecting a UART for RS232 comunication Quote Link to post Share on other sites

cde 334 Posted December 10, 2010 Share Posted December 10, 2010 Aside from the flash size being the major difference (and calibrated speeds), I assume they have a full portB gpio. But again, it just seems like they are cannibalizing the msp430f2xxx line with these new valueline chips. Anyone know a TI engineer that can explain the reasoning?

Anyone know a TI engineer that can explain the reasoning? I had assumed the value line was going to be the F-series without calibrations. I too am confused about what TI is doing.

simpleavr 399 Posted December 11, 2010 Share Posted December 11, 2010 according to the ti value line roadmap http://www.ti.com/ww/en/mcu/valueline/i ... e_Line&HQS scroll down to the "100 new device" the next batch is 64 devices w/ up to 8k flash, this may well be what gatesphere discovered in the new headers. the new feature would be just 2 full 8 bit ports, plus capacitive touch. and 20 pin dip packages I was expecting a UART for RS232 comunication the next next batch is 68 devices w/ up to 16k flash (assume no header files in the new CCS), these will have uart and more io pins (port 3?), but the extended io may not be available in dip packages, as dip devices will only be offered up to 20 pin. i hope i had interpret the diagram correctly.

cde 334 Posted December 11, 2010 Share Posted December 11, 2010 I read it the same way simpleavr. But then again, ttssop is relatively easy to use. And the launchpad is limited to the 2 port packages at max anyway, onboard atleast. By the time the next next batch is released, I'm sure TI will have a Launchpad2 or something. Tssop zif socket maybe? Quote Link to post Share on other sites
OCY 19 Posted December 11, 2010 Share Posted December 11, 2010 a) Do these chips have BSL ROM? The current G2xx1 do not have BSL ROM. Are the link command files for these chips in the newest CCS? If so, they should show the size of RAM and Flash. gatesphere 1 Quote Link to post Share on other sites

I just didn't look into it. I suppose I will later today, and confirm. Quote Link to post Share on other sites
NatureTM 100 Posted December 11, 2010 Share Posted December 11, 2010 I couldn't wait. I looked at the linker command files and unfortunately it appears the 4 new chips gatesphere listed have 2K flash. The good news is that they have 256B RAM. EDIT: I guess I was wrong about the flash. It looks like the 4 g24xx chips have 8k flash. gatesphere and bluehash 2 Quote Link to post Share on other sites
gatesphere 45 Posted December 11, 2010 Author Share Posted December 11, 2010 Incorrect... looks like I was right for at least the G2452. It lists flash length at 1FE0 = 8160 bytes ~8K. I'm looking into the others right now, but I'm assuming I am correct. You're correct about the RAM though. Which is a good thing. EDIT: Just updated my blog post, check it out. I was right about my predicted flash sizes. Thanks to OCY and NatureTM Quote Link to post Share on other sites
timotet 44 Posted January 5, 2011 Share Posted January 5, 2011 I just sampled 4 of the msp430g2452 in 2 different packages. TI said they were back ordered till jan 20th. I need more I/O. woot! 8-) Quote Link to post Share on other sites
OCY 19 Posted January 6, 2011 Share Posted January 6, 2011 I think the digit after G2 tells you the Flash size. 0=>0.5kB, 1=>1kB, 2=>2kB, 3=>4kB, 4=>8kB. Quote Link to post Share on other sites
gatesphere 45 Posted January 6, 2011 Author Share Posted January 6, 2011 I think the digit after G2 tells you the Flash size. 0=>0.5kB, 1=>1kB, 2=>2kB, 3=>4kB, 4=>8kB. Yeah, that's the trend that led me to make my predictions about flash sizes. Quote Link to post Share on other sites
timotet 44 Posted January 6, 2011 Share Posted January 6, 2011 yea, they have 8kb of flash and more i/o = sweet Quote Link to post Share on other sites
