manhdan 1 Posted June 18, 2014 Share Posted June 18, 2014 I simply open file StellarisOW.ino in GFDS18B20V2.zip and not add any of the sleep functions. It doesn't work with new Energia.h and wiring.c I tried with examples of Energia and my other projects, sleep() function works very well Quote Link to post Share on other sites

roadrunner84 466 Posted September 17, 2014 Share Posted September 17, 2014 laughpad? I prefer the Jollypad, but it's hard to get them... dubnet 1 Quote Link to post Share on other sites
dubnet 238 Posted September 17, 2014 Share Posted September 17, 2014 I have heard the GoodHumorPad works well, but only at lower temperatures.... Quote Link to post Share on other sites
phaseform 3 Posted September 23, 2015 Share Posted September 23, 2015 How can I remove power from the ICDI on a Launchpad board? It seems my lm4f120 will use 40mA through my usb power meter when in sleep, and 70mA when not in sleep.. (sleepSeconds)I've been looking through the users manual on the product page and can't find anything useful in the scematic or the hibernate section. Quote Link to post Share on other sites
roadrunner84 466 Posted September 23, 2015 Share Posted September 23, 2015 @@phaseform I don't think you can. The launchpad is your debugging tool, powering off the debugger would not make sense. If you want to power the MCU from USB, just use a power regulator. Quote Link to post Share on other sites
phaseform 3 Posted September 24, 2015 Share Posted September 24, 2015 I'm just thinking in as far as using the launchpad for a project, unless I'm understanding the process wrong, the debugging chip is only used as usb serial and debugging?Yer thats what I thought, if I remove the jumper possibly I could remove the ICDI from VBUS? then I'd just have to use an external 5v other than USB..?

B@tto 51 Posted September 24, 2015 Share Posted September 24, 2015 If you remove he jumper, you will not supply ICDI and you will be able to supply MCU through USB, but the 3V3 is supply by a LDO so it will still consumme a little bit of current. The best way is to supply 3v3 from external lithium battery for example. Quote Link to post Share on other sites
