rockets4kids 204 Posted October 28, 2014 Share Posted October 28, 2014 Which distribution list was that? This came up on irc a few days back... More information in this thread: http://www.electro-music.com/forum/topic-52377.html&postorder=asc Quote Link to post Share on other sites
vinicius.jlantunes 50 Posted October 28, 2014 Share Posted October 28, 2014 It's a list I joined after attending an MSP430 training. I think it is owned by the guy who did the training (Alessandro, from Techtraining), but he has a very close relationship with the local TI office here in Brazil so it serves almost as their "official" list locally, a person from TI often advertises their trainings, events and new products through there. texasinstrumentsbrasil@gmail.com The list is in portuguese though.

bluehash 1,581 Posted November 3, 2014 Share Posted November 3, 2014 I got this one in a distribution list about MSP430 I am subscribed to. http://www.korg.com/us/products/dj/monotron_duo/ It's a Korg synthesizer - and they release the schematics for those wanting to mod it: http://www.korg.com/download/global/monotron_duo_schematic/monotron_DUO_sch.pdf There you see an MSP430G2231. I did not figure out what it does. Nice find. Looks like it is monitoring analog inputs( Knob, Pitch, Gate ) and clocking( simple I2C ) the values to the main processor. vinicius.jlantunes 1 Quote Link to post Share on other sites
rockets4kids 204 Posted November 3, 2014 Share Posted November 3, 2014 The msp430 *is* the main processor on the monotron duo. ;-) Quote Link to post Share on other sites
bluehash 1,581 Posted November 4, 2014 Share Posted November 4, 2014 The msp430 *is* the main processor on the monotron duo. ;-) You are perfectly right. I mistook the clock/data lines for a slave device. Instead they are SBW lines. Quote Link to post Share on other sites
roadrunner84 466 Posted November 17, 2014 Share Posted November 17, 2014 Not entirely an msp430, but this RNG uses a CC3200. http://moonbaseotago.com/onerng/ Quote Link to post Share on other sites
chicken 630 Posted November 17, 2014 Share Posted November 17, 2014 Schlage smart door lock controlled by a MSP430: http://lowpowerlab.com/blog/2014/11/14/schlage-smart-door-lock-hackteardown/ Unfortunately no picture of the MSP430, but it's mentioned a few times in the write-up.

tripwire 139 Posted November 18, 2014 Share Posted November 18, 2014 Not entirely an msp430, but this RNG uses a CC3200. http://moonbaseotago.com/onerng/ The site says it's a CC2531 rather than CC3200 (Intel 8051 CPU instead of ARM Cortex-M4) Quote Link to post Share on other sites
vinicius.jlantunes 50 Posted February 11, 2015 Share Posted February 11, 2015 The Uni-T UT71E multimeter that Dave Jones didn't like the other day has an MSP430 inside. The meter is bad but at least they use a decent micro :-) It's a MSP430FE425: http://www.ti.com/product/msp430fe425 Link to the video - the MSP430 is visible 14:21 minutes into the video. http://www.eevblog.com/2015/02/07/eevblog-712-uni-t-ut71e-multimeter-why-uni-t-meters-suck/ bluehash 1 Quote Link to post Share on other sites
chicken 630 Posted August 27, 2015 Share Posted August 27, 2015 Reviving an old thread, the Fitbit Aria Wi-Fi Smart Scale features an MSP430F2013. According to this article by Bolt, a hardware accelerator / VC fund, the MSP430 is part of the circuit to measure body fat. The circuit also features two TI op amps (TLV272, TLC274B), which makes me wonder if there's a TI app note about that. There's actually a fully integrated analog front end from TI for a weigh scale with body fat measurement: AFE4300, including a reference design for a scale with BLE. Bolt's blog is a pretty interesting read if you're interested in taking your widget beyond the prototyping stage. bluehash 1 Quote Link to post Share on other sites

I've been there a few times for their hardware startup meetups. Pretty cool guys with an awesome workshop to develop your ideas. The article was a nice read. Quote Link to post Share on other sites
greeeg 460 Posted November 26, 2015 Share Posted November 26, 2015 Was reading this article about the new Macbook charger.http://www.righto.com/2015/11/macbook-charger-teardown-surprising.html Look what we have here! I'm not sure what it actually does, there is already a dedicated SMPS IC and a PFC IC. It might implement an intelligent over current cutoff? bluehash and roadrunner84 2 Quote Link to post Share on other sites
maelli01 74 Posted November 27, 2015 Share Posted November 27, 2015 My high tech, German street legal, bicycle light failed. Corrosion on the battery contacts, one day it worked, the other not.So I cracked the damn thing open. Solid build quality, waterproof, but not built to be repairable.As far as I remember, I bought it back in 2006.So what is inside: An MSP430F1122, doing all the business:- Battery charge termination (four AA NIMH)- Two LED intensity levels PWM- 2 color status led (blink duty cycle would indicate remaining charge) - Pushbutton, long for on/off, short for low/high The electronics still works fine, but would need a lot of duct tape to make it a cycle light again :-( bluehash and pneumatics 2 Quote Link to post Share on other sites

cde 334 Posted November 30, 2015 Share Posted November 30, 2015 Was reading this article about the new Macbook charger. http://www.righto.com/2015/11/macbook-charger-teardown-surprising.html Look what we have here! mps430.jpg I'm not sure what it actually does, there is already a dedicated SMPS IC and a PFC IC. It might implement an intelligent over current cutoff? From the same link This 16-bit processor constantly monitors the charger's voltage and current. It enables the output when the charger is connected to a Macbook, disables the output when the charger is disconnected, and shuts the charger off if there is a problem. This processor is a Texas Instruments MSP430 microcontroller, roughly as powerful as the processor inside the original Macintosh. The microcontroller circuit board from an 85W Macbook power supply, on top of a quarter. The MPS430 processor monitors the charger's voltage and current. The square orange pads on the right are used to program software into the chip's flash memory during manufacturing. The three-pin chip on the left (IC202) reduces the charger's 16.5 volts to the 3.3 volts required by the processor. Spy-Bi-Wire broken out. Hmmmm bluehash 1 Quote Link to post Share on other sites
