Thank You Warren. Pretty good overview. Looking forward to the rest of the classes.

Iron

We've used batteries and MAINS power sources. I am interested in learning more about energy harveting.

Iron

I am a software engineer, my primary focus is embedded software development. I have spent the last 23 years working in the medical device industry.

Iron

Downloading course materials.

Iron

Hello from Beaverton, Oregon

Iron

hello all from Edmonton, Alberta.

Iron

thanks once again for an excellent presentation sir warren, much appreciated...a good lecture that collects another ideas...

thanks to all and most especially DIGI-KEY and DESIGN NEWS for giving this continuing education, a valid educational earner as a practicing engineer in the profession...

i will go to the next lecture for day 2 presentation...thanks sir warren...GREAT!

once again, its about to end and will look forward for the next lecture as day 2 continuation...

i am now on slide 18...

i am now on slide 16 of the lecture...

i am now on slide 7...

i am now about to begin with the lecture of sir warren...

i am now downloding the resentation slides for this lecture...thanks once again...

good afternoon sir warren...nice meeting you

Yes I used Hibernate stop mode in current project

Iron

battery Li-ion battery Silver Oxide battery

 

Iron

Warren - thank you for this overview and i am looking forward to the next session

Iron

batteries and power supplies

Iron

hello - better late than never

Iron

Good overview and the course outline looks good.  So as not to be labelled mere 'techies' or 'hardware weenies' I would like to see a few slides regarding concepts/strategies/approach/methods for when to transition the varying power modes.  The rationale slides were good.

Great to have access to the recorded sessions!

Iron

Better late than never...

Iron

Taking the offline class

Iron

Hi Warren

I am an analog guy so thanks for the series. I did the first one and will do the rest.

Constructive point. Try to use Umm's less.

Cheers

Timothy

Iron

Hi, My name is Mike and I am an electronic telecommunications tech. I am joining you guys to

learn more about certain electronic components and the uses for them in this ever changing field

that I love so much. I have many years of experience as a repair tech, but would like to get more into

designing. Thank you for your cooperation.

 

Iron

Plan on using rechargable dc power in the future

 

I have had any low power micro need in the past

Picking up another class a bit late

I have used interruption and two christal im my projects.

Iron

I have used WDT for one of my application. I was using LPC1343 from NXP for my design.

Iron

What is the difference between Pipelined Excution & Intelligent Control- Low Power?

Iron

I use battery DC and Adapter DC power for my designs.

Iron

What is the benefits and trades-off of executing program from RAM?

Iron

@garysxt: Does PoE mean Power over Ethernet? What is line voltage?

Iron

@Warren: How could we measure the power consumption of the board in the case it run in very low power mode? I guess they dont have to wait for weeks or months to give a conclusion?

Iron

Catching up. Firmware Engineer working in the medical devices market.

Iron

Missed live presentation and catching up for the next one. Have used line voltage, PoE, battery for power source. Working on a project using solar.

Iron

used mcu with remote controls (halt mode) and water meters (halt mode) and also couple of sleep modes

Iron

use ac/dc power supplies and batteries

Iron

Thanks Miller, excellent presentation

Iron

Cannot load the WE Energy harvesting brochure document (slide 19)

Thank you.

 

Iron

Thanks for presentation...

Iron

used  sleep mode when their in no input after checking input for some time.

Iron

Hope to see you all at the next class- and at all the rest of the classes this week!

Thanx for attending.

Iron

Sorry running late today.

 

Iron

Thank you Warren for very good start, looking forrawd for more! Now is a reading time... :)

Anatolly1086- Strange, Must be a tinyurl glitch. Thanx for checking.

Iron

Anyone else have any other questions?

Iron

@Warren: I have Chrome browser, Note I have checked all links a few days ago they all had worked, but today the top one does not.

Skechy- The term Gated for the CPU clock basically means that the clock to the CPU is turned off (usually a gate is placed such that the clcok can be forced high or low- thus "Gated" off. This helps reduce dynamic current since nothing in the CPU will change state while the clock is Off.

Iron

kzmackay- Rechargable batteries are the typical approach. A super cap might work too however. Take a look and see if that will work for you.

Iron

@gordon: I have mine Starbucks GC by email as print type

>30 years of electronic product design in Portland Oregon

Iron

ChrisJ- Rework on proto PCBs- interesting. I hadn't thought about that. Is this from needed to resolder components or something else?

Iron

For energy harvesting (solar), do people typically use in conjunction with rechargeable battery? I'm finding that the rechargable version is boosting cost considerably.

Iron

Anatolly1086- Good to know they work OK for you. What browser are you using?

Iron

How do you know if you will receive a Starbucks gift card?

Iron

We've also found a lot of other things that contribute to energy use.....like rework on proto PCBs.  Also, 70uA for a battery gas gauge becomes a lot when you're aiming for 150-200 uA in standby!

Iron

The list of links at slide 19 are all clickable and all worked for me...

thanks for the first day, until tomorrow.

Iron

Solar power is also a very interesting power source. It can be fairly complex, but there are some good devices to help with harvesting solar at low currents available. Look for this to be a big growth area.

Iron

Looks like several people have used low power modes- thats probably the most important way to reduce your power consumption.

Iron

Thanks for the link!

 

Iron

Here is a link to the web page for the energy harvesting kit: http://www.we-online.com/web/en/electronic_components/produkte_pb/demoboards/energy_harvesting/energy_harvesting.php 

Iron

Looks like only the first link is broken. Others are OK.

Iron

If clickable links don't work just copy and paste in browser TI link with copy paste worked.

Iron

Great presentation, thanks.

Iron

Good lecture!

Keep up the good work, please.

Thank you. Rod. R.

Iron

Chris-

I will add the links in the chat later today so come back to it if you need to.

Iron

Great class. Hearing about other people's projects was interesting also.

Iron

Great Intro Looking forward to tomorrow's lecture

Iron

Thanks Lauren & Warren

Iron

We will discuss the use of external components in future classes. Thanx for the suggestion.

Iron

Thanks for the intro...

FYI, the first link on the "resources" slide (WE Energy Harvesting brochure) doesn't work.  The TinyURL redirects, but nothing comes up.  Haven't checked the others. 
Also, can I request that you make them actual clickable hyperlinks?

Iron

Thank you , that was my first time speaking about lower power MCU , It was very interestin

Arseny Vuzman

Iron

When we want low power, we shut down entire MCU and then have various external triggers to wake-up the MCU's power supply. 

Iron

Warren thank you for this great presentation.

Iron

Thanks Warren & Lauren.

Iron

Thanks, looking forward to tomorrow Warren

Iron

first link (WE Energy not working, others are ok)

Iron

Got down to less than 100uW with an external crystal using TI MPS430.

Iron

Early PIC ones that were timer (WDT), not event driven.

Iron

I've used a number of different low power features.  Sleep mode, reduced clock freq,  turning off features that aren't needed, irq.

 

try to make extensive use of sleep, watchdog and interrupts

Iron

I've used very low power modes.  Usually having everything shut down waiting for an interrupt or a watchdog timer wake up.

Low power, suspend mode for ARM and FPGA 

haven't used low power before

Iron

Often used sleep modes and wake-up on timer to reduce power usage.

Iron

what is the meaning 'Gated' in CPU clk gate?

Iron

i have used designs that vary the MCU frequency as needed. 

Iron

automotive keyfob design used wake on keypress - coin cell battery needs to have 5 year lifetime before change

Iron

sleep mode for remote, battery backed SRAM

Iron

Yes, low power RF designs

Iron

Used low power modes on MSP430 and LM4F120 TI M4

Iron

I've only used sleep to minimize consumption so far

Iron

Yes, putting processor to sleep, and waking up only after a key is pressed

 

Iron

ok

 

Thank you very much

Iron

Just audio and you will need to download the PPT presentation

 

Iron

I have audio now.

Is there video with this presentation or just audio?

 

Iron
