Products using MSP430

97 posts in this topic

A recently purchased Electro-Harmonix volume pedal for musicians contains a MSP430.  It's part of thier EHX next-step effects line.  They have a couple other foot pedals that may or may not use a MSP part as well.

I got this one in a distribution list about MSP430 I am subscribed to.

It's a Korg synthesizer - and they release the schematics for those wanting to mod it:

There you see an MSP430G2231. I did not figure out what it does.

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.

The list is in portuguese though.

Nice find.

Looks like it is monitoring analog inputs( Knob, Pitch, Gate ) and clocking( simple I2C ) the values to the main processor.

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.

Reviving an old thread, the Fitbit Aria Wi-Fi Smart Scale features an MSP430F2013.

 

post-9974-0-65290600-1440645566.jpg

 

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.

:P  The Bolt facility is in Boston. 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.

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 :-(

What is the model name? 

Thanks for the pics.

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?

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
