I'm curious about the specific recommendation "just make sure it is a ceramic capacitor", since even the datasheet application circuit indicates a polarized electrolytic capacitor instead. Is there a basis for this recommendation? — Anindo Ghosh 10 mins ago

Anindo Ghosh

@angelatlarge Hiya :-)

@angelatlarge Why "ouch"? The recommendation was clearly pulled out of someone's arse.

angelatlarge

@AnindoGhosh Exactly. Your comment is a fine example of walking very softly with a ginormous stick in tow :)

Anindo Ghosh

@angelatlarge Heh

angelatlarge

Did you UV this?

A: Free circuit simulator for educational purposes

PartSim is a free and easy to use circuit simulator that runs in your web browser. It includes a full SPICE simulation engine, web-based schematic capture tool, and a graphical waveform viewer. It also includes an integrated Bill-Of-Materials manager that lets you assign Digi-Key Part Numbers to...

@AnindoGhosh Not that you need to report to me on such matters.

@AnindoGhosh Useful answer, but it is composed of marketing blurbs from the website, posted by a new user. Likely to be a plant, I would think.

Anindo Ghosh

@angelatlarge No, I did not - I had not even noticed. Also, pretty much every answer to that question bigs up the respective poster's tool of choice, and most of them are merely links or at most link + copy-paste. Frankly, I think CircuitLab sucks in its terribly limited choice of components and in the messy way simulations are done, but we're using it, aren't we? I'm glad Falstad got "accepted", not because it's much better (it is), but to cock a snook at the tool we are constrained to use instead.

@angelatlarge Ahhh that clown came back with a rebuttal without bothering to check the datasheet diagram. He needs a few more DVs.

angelatlarge

4:45 AM

@AnindoGhosh I am constrained not to DV that one because it is out of my range of knowledge.

Anindo Ghosh

@angelatlarge :-) Fair enough. This wasn't knowledge-constrained, it was datasheet-explicit-component-indication-constrained.

angelatlarge

@AnindoGhosh Datasheets make mistakes. Plus takes knowledge to read a non-mistaken datasheet, as @rawbrawb has demonstrated to me the other day.

Anindo Ghosh

@angelatlarge Of course. Remember the TLC headroom reading from the diagram?

angelatlarge

@AnindoGhosh 1.2 (or so) @ 120mA

@AnindoGhosh And about 0.3V @ 20mA

Anindo Ghosh

@angelatlarge By the way I left you a couple of messages on alternatives to the shift register, which will do constant current 16 channel output at reasonable prices and speeds.

angelatlarge

4:50 AM

@AnindoGhosh I still hate that diagram.

@AnindoGhosh Yeah, sorry, I meant to responed. Shift register requires too many updates to do effective even 16 intensities. TLC5490 all the way, baby :)

@AnindoGhosh You can get them at $1/piece on Ebay, though only DIP, not SMD, unfortunately. This is in quantities of 50+

Anindo Ghosh

@angelatlarge Did you see the datasheets? I believe one of them (both?) was a straight SPI part with latching and no additional blank etc needed.

angelatlarge

@AnindoGhosh But if it is just a straight-up shift register, then I'd have to do the PWM from the processor, right? I took you are your word when you said "shift register".

@AnindoGhosh (I think you said "shift register", didn't you?)

Anindo Ghosh

@angelatlarge Please see the datasheets, my notes indicate that those parts were meeting multiple criteria, so PWM might be part of it.

@angelatlarge A TLC5940 is a shift register too :-)

angelatlarge

@AnindoGhosh Ah, OK.

@AnindoGhosh No! It's a PWM LED driver!

@AnindoGhosh I am a shift register.

@AnindoGhosh What do you know? STP16CL596: Low voltage 16-Bit, constant current LED sink driver

@AnindoGhosh Cool, let's see...

@AnindoGhosh The datasheet I have is marked "obsolete"... Ebay has almost none...

@AnindoGhosh 3.6 max voltage. I might want a 5V part

Anindo Ghosh

@angelatlarge I think it got replaced with an SMD-only part number.

angelatlarge

4:58 AM

@AnindoGhosh Ah, let me check..

Anindo Ghosh

@angelatlarge Oh wait, the CL596 is the low voltage version, search for it without that L.

angelatlarge

STP16CP05 does 5.5V max, 30mhz clock, so far so good...

Anindo Ghosh

That chap's comeback of "It need not be an electrolytic, it could be a tantalum capacitor" made it amply clear what his knowledge level is. I see no point arguing with a fool, they will drag you down to their level and then beat you to death with their ignorance.

angelatlarge

@AnindoGhosh Can you enlighten me then? Why is it important for the cap there to be electrolytic?

@AnindoGhosh Or is it just that his claim of ceramic is bogus?

@AnindoGhosh The prices are disappointing. Ebay hardly has STP16CP05s, and digikey has them for $1.38 in qnty 50.

Anindo Ghosh

@angelatlarge It isn't: Electrolytics are cheaper and more ubiquitous at the relatively large capacitance of 1+ uF, and for the specific purpose of low-passing a low current power feed, the X5R recommendation is bogus.

angelatlarge

5:05 AM

@AnindoGhosh I see. Thank you.

@AnindoGhosh Then that tantalum cap might set you back almost as much as the tantalum resistor. Tantalums aren't cheap.

Anindo Ghosh

@angelatlarge ...and a tantalum cap is totally not needed there either.

It's evident now that that chap doesn't even have a clue what that resistor-capacitor combination is doing - or he might know now, after reading my answer.

angelatlarge

@AnindoGhosh @AnindoGhosh: as you sock puppet, I would like to humbly suggest that you will not like that comment that you left about srafy's impressive knowledge. You might want to edit it.

Anindo Ghosh

@angelatlarge OK

@angelatlarge Too late to edit, and the bit about Tantalum caps being electrolytic needs to be there, so ... oh well.

angelatlarge

@AnindoGhosh One of the nicest things about having you around here is how classy you stay, no matter what, and by acting so thusly you promote general classiness around you. We all benefit from that. It would be too bad if that comment stays etched in stone there :(

Anindo Ghosh

@angelatlarge Actually that comment is the classy edition of "You, sir, are a moron" :-)

angelatlarge

5:13 AM

@AnindoGhosh That comment would be a tad classier if it made no reference to the knowledge bit :)

Anindo Ghosh

@angelatlarge And thank you for that vote of confidence. I really appreciate it.

angelatlarge

@AnindoGhosh I meant that very sincerely.

@AnindoGhosh When I get annoyed/bothered by beginners, for instance, I always try to think "What would Anindo do?"

Anindo Ghosh

@angelatlarge No doubt. Which is why I went and actually tried to edit it. The reason I won't delete it outright is, that would propagate misinformation that a tantalum cap is not electrolytic.

@angelatlarge I know, I realize that perfectly, it truly made me smile.

angelatlarge

@AnindoGhosh Oh, whoops, STP16CP05 is not a PWM chip.

Anindo Ghosh

@angelatlarge C596

angelatlarge

5:20 AM

@AnindoGhosh But a very nice one nonetheless

Anindo Ghosh

@angelatlarge And what about the Allegra part? They do samples too, and 3-day UPS of said samples.

angelatlarge

@AnindoGhosh Also EOL

@AnindoGhosh Getting around to that...

Anindo Ghosh

@angelatlarge If those are all EoL, then typically a SMD / BGA equivalent would already exist.

angelatlarge

@AnindoGhosh I think it must be the STP16CP05

@AnindoGhosh Ha! The allegro part is EOL too.

And it isn't PWM chip anyway.

Anindo Ghosh

One exception that comes to mind, and one that I really found strange, was the LM3914 dot/bar LED driver. It made no sense to me that the product went EoL despite millions of units moving per year, and despite the fact that there is no other component with that simplicity of implementation, for 10 outputs, that I could find. Sure, it can be done using an MCU, but that needs clocking etc. If you know of a replacement, I'd be very interested.

angelatlarge

5:28 AM

@AnindoGhosh It took a voltage and gave you bar-graph type output?

Anindo Ghosh

Ahh I see that the LM3914V does exist, in SMD. Yay! That's a relief.

@angelatlarge Yes, bar or moving dot. Voltage relative to Vcc

angelatlarge

@AnindoGhosh Sounds cool. I have played around with that kind of stuff in years though.

Anindo Ghosh

@angelatlarge It sells when incorporated into a product. Users love it.

angelatlarge

@AnindoGhosh Yeah, I believe it.

Weird question, no?

Q: Storing info bytes in ATmega169PA that remain after reprogramming

Does anyone know if there is a way that I can store 2 bytes of data into an ATmega169PA that will survive re-programming of the device? I would like to store a unique ID into an ATmega169PA that will remain in the device even if I erase both FLASH and EEPROM or reprogram the device with a new app...

Anindo Ghosh

@angelatlarge Yes, notice my comment.

angelatlarge

5:32 AM

@AnindoGhosh I did. I left a comment too. I think it is instructive to consider what the OP is asking for. Write-once read-only memory.

Anindo Ghosh

@angelatlarge There are MCUs with such a bank, but that one isn't it.

angelatlarge

@AnindoGhosh There is a way of doing that, sort of I would think: burning out selective IO pins. Trouble is that if you need 16 bits, you'll be left with a..hmm.... let's call it "reduced" ship.

@AnindoGhosh In the old days all "MCUs" were like that: PROMs.

Anindo Ghosh

@angelatlarge My reason for asking was: Why would you care about specific ID bytes, when the person doing the wiping actually has access enough to wipe out everything. It's not your typical forensic stuff, so it might be that the OP is not clear on what they need.

@angelatlarge The "because why" made me spew coffee on keyboard.

@AnindoGhosh you really want a new keyboard don't you?

@CamilStaps No, just a good java nose flush

@CamilStaps Some people call it detoxing

@CamilStaps Though it being coffee, maybe the right word in this case would be proboxification.

@angelatlarge It was funny because I pictured you with a scowl on your face, one eyebrow arched, saying "Because why?"

On a different note, does anyone know of, or can identify, a 16-channel linear bar / dot graph LED driver, something like the LM3914 but with 6 more outputs? SMD preferred, but TH will do as well.

@angelatlarge Won't be any use - Patent Attorneys aren't real lawyers anyway :-) And besides, I assume your manufacturer is not in India.

angelatlarge

@AnindoGhosh They are close.

Anindo Ghosh

@angelatlarge Nope, at least around here it's essentially a clerical function.

PeterJ

@AnindoGhosh, do you need to be a patent attorney to file your own patent in India? Here I'm pretty sure anyone can do it - you only need to be a patent attorney to do it for others and I think they need the full four-year law degree.

angelatlarge

@AnindoGhosh Sorry, I was referring to the geographic proximity.

Anindo Ghosh

@PeterJ You need a patent attorney to actually have any hope of getting the patent through. Self-filings are not permitted.

angelatlarge

@AnindoGhosh Self-flagellation, on the other hand..

Anindo Ghosh

@angelatlarge Ahhh, the vagaries of ambiguous textual communication :-)

@angelatlarge Is entertaining to watch.

@angelatlarge Oops, TMI ;-)

angelatlarge

@AnindoGhosh Wait, if self-filings aren't permitted, how is being a licensed patent-filer is going to help, unless you get a whole new identity in the process.

PeterJ

@AnindoGhosh, ahh different to here then (unless it's changed). I think you pay a few hundred dollars and they accept just about anything (within reason) although of course many amateur attempts wouldn't really hold up if challenged.

angelatlarge

@AnindoGhosh Unless done by a bacteria.

Anindo Ghosh

@angelatlarge Basically you can file for yourself, but you have to fill the column for "Filing Patent Attorney (Full Name and Regn. Number)", even if it is with your own name and registration number. That column is not optional and "N/A" or "Self" are not allowed.
