Urgent Requirement for LCD specification & Manufacturer for MSP430F6779 Unit

With all due respect, Here

 Hi Brian, I found no magic universal unknown LCD but thanks a lot for this good link I saved for similar question rain drop on every forum.

Hi Brian,

Instead of generating automaton responses to valid queries, I should ask you - for all the developers who are working independently on the MSP430F6779 smart meter - if an important singular display component like LCD is not available universally - WHAT IS TO BE DONE.

The Texas Instrument MSP430F6779 meter IC has a built-in LCD driver.  An LCD with 4 COMs x 40 SEGs (44 pins) is requested.  This would be a glass display only, with no driver circuit. So due to unavailability the project abruptly ends there itself.

Going ahead, I am funding  "VISHAY" to custom built the said LCD, so that it is available to all members of the TI community working on the smart meter platform and all MSP430F6779 meter IC in the future. The said product will be ready in 2 months time.

Thanks a lot for your response and I hope that in future if someone asks a valid point - please do not respond unless you have a solution in hand.

with all due respect.

 Uhmmm from your original post I don't see how to help you:

Hello,

I am working on assembling a MSP430F6779 Unit, I would like to know the manufacturer name and specification of the LCD Displays of 44 pins required for 160 segments in 4x40 mode.

Regards,

 So I can reverse your writing to:

 Please dont ask for question never someone can answer? Did you grasp your question was not detailed? MPS part drive a lot of LCD glass and which one are you speaking about?

 So NOW after posting all details someone can help you.. BUT BEFORE to you NEED APOLOGIZE Brian.

 Your WASN'T A valid request!!! Sorry if our answer hurted you but there where some forum usage rule none respect as from your case. So please get your part of guilty and do what is necessary otherwise to get clean forum usage none answer you.

 No problem with you but I wish avoid war than help and have a clean smart happy forum.

Your question was vague and with no details. We get a lot of those here, usually by college kids working on a class project. Be specific. Your question comes across to others as you did no work and expected others to do it for you.

You didn't search very well. There are plenty of companies and types of LCD segment arrangements available off-the-shelf. A quick search turned this up: http://www.digikey.com/product-detail/en/LCD-S401C39TR/67-1792-ND/469781

Often times, coaxing the OP to provide more details does indeed lead to a solution.

 Hi Brian, the display is not the one of kit custom. Obtain a custom is not more expensive and just 1000Pcs align cost to stock one, if this was a production eng then question was posed in different manner....

 I stop answer to people using offensive answers so after apologizes I decide help or not.

To be fair, the OP didn't ask for the LCD that was on the energy meter dev kit that TI sold. He asked for one that would work with the part.

As far as the energy meter, there was a thread some time back about that LCD (I'm not going to dig it up myself) and IIRC, the answer was that TI had that made special for the kit and didn't have further stock that could be sold.

I guess you would expect that user's would buy the dev kit for rapid prototype, and then have a custom display made for their mass production end product. You know, with things like custom segments that indicate mode and what is being displayed.

So, I think the answer for those that come along later is, use a COTS display or have a custom one made like the OP seems to have done. My 2-cents.

 Just save 1 cents, if you see the other request of our poster we just evaluate who is.. It is searching a simple ferrite bead suppressor, same similar text and is not able to extrapolate the two parameter and find tons of similar compatible too.

 So this is a loser. I don't forget to check for apologizes, I decided stop help who is using offensive answer.

Dear Brian and Roberto,

To both of you, please accept my apologies for starting this, and let us stop this here –

Just a thought – I have assembled almost all of the smart grid products from scratch and they are progressing well. Has anyone noticed that for a small time developer working on the smart grid products – the BOM’s are pretty outdated? Some of the components are not in the production cycle at present.

As for the LCD and the ferrite beads, I went ahead and custom built them from large manufacturers, but for a small time developer tinkering and learning about the TI products – it will be a tough play and large suppliers will not oblige.

There should be a sub-community thread dedicated to components associated with the smart grid BOM’s for the little guy, in which people should be given a chance to talk about updating BOM’s and sharing notes and for people like me to update alternate products for any small tinkerer.

Again this was a thought; please do accept my apologies again.

Regards,

Ramyo

I've been here long enough to not take things personally, so don't worry about that. I think my advice is to make sure your questions have sufficient detail so that we understand what you are trying to accomplish, and what you have tried already. That makes your question stand out from the college kid "please do my homework for me" stuff we get here.

 So are you building a single piece from scratch (following dev kit schematic)? This cost a fortune, maybe an hobby to pass a lot of time doing something is out of my concern.

 Every time we start a project we think in term of availability of single component and we try provide a multiple source for critical part like one custom LCD.

 A BOM assembled today with a part found from some manufacturer nowaday can become obsolete in term of single day. When a primary silicon part fade out project is dead and need reborn. When a single passive component get out of stock is more simple, we can identify parameter then do a new search possibly checking "in stock" filter.

 Cost and time making one sample PCB and one sample LCD (around 500US$) discourage from build one piece from scratch than buy devkit, build 1000 where cost  of LCD sunk above .5+.5 US$, PCB and component too again fall down to production price, unit cost a fraction of devkit.

 Wrong is your asking mode, if you start from:

 Please I wish do this and I need help on locating these yyy part for a single unit, can someone help me locate where can I buy custom part?

 The cheap answer can be, buy a dev kit and take part from it.

 So your search say project miserably failed... why you are searching for a standard LCD when on production lot a CUSTOM one cost less or similar?? ON a custom I can also add my logo too.

 ( I am no more  online so often as in the past.)

Ramyo, there is no "MSP430F6779 smart meter" (and in your original post, the term ‘smart meter’ didn’t exist at all. If you click on the automatically generated link on the product name, you see that the MSP430F6779 is a CPU, nothing more. And you can connect al kind of glass LCD to it, or none at all.

There is maybe an evaluation module based on this CPU, but this is a different thing nobody could know by your request.

It was like asking “Where can I get a graphics card for my Pentium processor”, not mentioning whether it is a PC or a MAC, running Linux or Windows or MAC OS with PCI, PCIe or whatever mainboard.

A valid query is a post that contains a question. So your query was maybe valid, but it was not answerable, because it did not contain enough information to limit the possible answers to less than ‘all or none’.

Now if you got an evaluation module, you’ll surely find a BOM on its product page, which contains a part number for the LCD used in this specific evaluation module. Nevertheless, those modules are for evaluating the features of the CPU, and are not intended to act as blueprints for clones. If so, TI could produce and sell them themselves.

Hi Syed,

You can buy them from ADKOM Elektronik GmbH.

Their contact email ID is info@adkom.de

Is there any alternate to this ?
