fatihinanc 14 Posted February 29, 2012 Share Posted February 29, 2012 The upper limit for RST capacitor is 2.2nF. Do you have a source for this information handy? I've been battling similar problems with the interesting twist being SugarAddict seeing kinda-sorta different behaviour on the exact same (production run) board. Smallest I tried was .1uF I think (also the LP schematics indicate LP uses 1nF, not really sure what was I thinking, but I'd like to read up on this now ). Yes. FET430 wire pinout(SBW) explain that BTW I have tested with 1nF capacitor too. Works gordon and oPossum 2 Quote Link to post Share on other sites
gordon 229 Posted February 29, 2012 Share Posted February 29, 2012 It works (well, for me) without that cap too (used that as a workaround). My jumper wires are 8-ish inches. Quote Link to post Share on other sites
nobody 47 Posted February 29, 2012 Share Posted February 29, 2012 It works (well, for me) without that cap too (used that as a workaround). My jumper wires are 8-ish inches. This capacitor (C14 - 1nF) is part of LaunchPad. If you connect programming wires to connector J2 connected to socket, you not need it. Of course, if You use J3 or mini - connector J4 then 1nF capacitor is recommended (but not absolutely must-have...). Quote Link to post Share on other sites
TomKraut 17 Posted March 1, 2012 Share Posted March 1, 2012 The 1nF cap has nothing to do with programming. It is just there to prevent an MSP from resetting due to external effects like ESD. I never use it on a bread board, and of course it works, but I would always include it in a final design... a lesson I learned the hard way Cheers TomKraut Quote Link to post Share on other sites

MattTheGeek 99 Posted March 9, 2012 Share Posted March 9, 2012 I can also confirm that the Launchpad V1.4 and V1.5 will program external devices (F5510)... Even in CCS (No more Device not supported, etc...). Only drawback is that SBW is quite slow... I have also been able to program a few devices with 16" jumpers...

fatihinanc 14 Posted March 9, 2012 Share Posted March 9, 2012 I have both of v1.3 and v1.4 version LP's and I have found a wiki page about updating eZ430. I've updated my LP's using FET430 UIF and now both of LP's, programing F5x devices too fast. And after the programming Flash(Quick Download in IAR, without Debug) the Reset button is works. In the older revision, I have to unplug and plug the LaunchPad for running the downloaded code. I strongly recommend it Specifications of eZ430 Firmware V30394216 Release Date: 11/09/2011 Supported Features: LPMx.5 debug support( if device supports this)FRAM memory technology supportFR5739 MPU handlingFastEasy: fast FLASH and FRAM programming Supported Devices: CC430 FamilyFR573x Family5510 Family5529 Family5172 Family5438 Family5438A Family2GXX Family2xx Family Supported Tools: CC430-EXPFR5739-EXP5529-EXPFossil WatchChronos WatchLaunchpadez430-2500RF This is the link : http://processors.wiki.ti.com/index.php/EZ430_Emulator_Upgrade jazz 1 Quote Link to post Share on other sites
bluehash 1,581 Posted March 9, 2012 Share Posted March 9, 2012 I've updated my LP's using FET430 UIF and now both of LP's, programing F5x devices too fast. It says it is only for the ez430 , not the one on the LP. Did you reprogram your LP? Quote Link to post Share on other sites
fatihinanc 14 Posted March 9, 2012 Share Posted March 9, 2012 Yes. Supported Tools:Launchpad But this firmware supports LaunchPad. I did reprogram my LP's and FraunchPad. They still working stable. Quote Link to post Share on other sites
surajms 0 Posted March 27, 2012 Share Posted March 27, 2012 so to use the launchpad as an external programmer we need to remove the 100nf C2 capacitor and use the SBW wires right. Quote Link to post Share on other sites
SugarAddict 227 Posted March 29, 2012 Share Posted March 29, 2012 No, you do not need to remove anything. I program most of my stuff with the LP and never stick a chip in its socket. I've even broken/removed the socket from a few LP's Quote Link to post Share on other sites
Nytblade 24 Posted May 25, 2012 Share Posted May 25, 2012 What is the purpose of having TXD and RXD connected to P1.1 and P1.2 on the Launchpad board? Are these used at all for programming or what? Quote Link to post Share on other sites
SugarAddict 227 Posted May 25, 2012 Share Posted May 25, 2012 Virtual Com port on the USB. Not required for programming. Nytblade 1 Quote Link to post Share on other sites
tonesenna 20 Posted October 16, 2012 Share Posted October 16, 2012 Hello, There is some good news from my side that I would like to share in this same context. I have tested MSP430 LaunchPad to successfully program MSP430F5310, MSP430F5418 and MSP430F5438 over SBW!! :thumbup: I would detail the setup in my blog. These are all bigger microcontroller and have lots of features. They are the ones I use to make embedded products at work. Some of them can give a battery lifetime of 5years on 2.4G Wireless networks. Well now I can use them at home too. Thanks to TI , MSP430. And a Big Thanks to the 43oh Community :clap: I have new board coming up that I have developed using MSP430F5310. Hope that this would enable more advanced projects. This is great News! Did it need any special procedures to get done? regards, --to Quote Link to post Share on other sites
petus 11 Posted November 4, 2012 Share Posted November 4, 2012 Hello, I wrote page about programming MSP430F2132 with LaunchPad today. http://chiptron.wz.c...ramming-sbw.php cde 1 Quote Link to post Share on other sites
