Background: For a number of years, we've been putting 2x8 character LCDs on "little" controllers. Typical is Hantronix http://www.mouser.com/ProductDet... at $4-$6 depending on volume. Module size about 60mm x 40mm; display area about 28mm x 12mm.

Then typical UI adds four push buttons MENU/SET/UP/DOWN. Say another $1 for that.

Let's say I want to get into a new decade and use a small graphics LCD instead. Perhaps with a simple touch screen also, to replace the UI buttons?

I've done a few T6963 graphics display apps before, but can I get small 128x64 or 128x128 or similar graphics LCDs at that ~$5 price point? Not surplus one-time buy; need to be able to re-buy.

I see that DigiKey has Varitronix modules at that price point.

But they are COG yet have a serial interface. I'm lost there--is there a controller on board then? Can someone point me to a primer on this?

Will a special connector add to the BOM significantly?

They seem to have an ST7687S controller.

I played around with one of those with :oops: Arduino code :oops: from Adafruit.
https://www.adafruit.com/product...

The one I used had a ST7735 chip. (for some reason can't attach datasheet!)

I'm now building up libraries fon several types of controllers, just got one working with 16, 8bit and SPI. So I'll probably add that as well.

Yes, but if you click through on the second DigiKey link it indicates a "Serial" interface, and clicking on the resulting Datasheets link gives a drawing that shows SCL/SDI lines and no Dn pins...and that particular model is nowhere to be found on varitronix.us.com http://www.varitronix.us.com/?pi...

So I'm still confused. ;)

No easy Google hits on that controller and "atmel avr".

It looks like no connector, should solder using hot bar soldering

Further thoughts: I'll have to think a bit whether my "small" controllers (e.g. Mega88) will have enough SRAM for what I'd want to buffer, and enough flash for a font (or two).

Not a bad price, tho, is it?

But I'm open to suggestions--the above are pretty fancy with the full color and all. Mono solutions in that price range?

ST7735 controller. That (as far as interfacing to micro) seems to be very similar to the ST7687S. Did you start from scratch or did you find code examples/drivers?

For sale or lease or lend or ... ?
So you did have success with those displays?
Is it as good a value as it seems?

The datasheet of the display isn't clear at the first read: Is a single supply voltage needed?

For the general purpose library I have used the code from http://www.circuitidea.com/dev-b... there is a version for GCC as well as Arduino. I have spend several months on and off modifying the code to make it easier FOR ME to use and have used it with several size displays and controller types.

For the small Varitronix display I just use one of the examples from the Arduino. It runs at 3.3V (as most GLCD do)

This Cecil B. DeMille production :lol: takes 60.5K flash and 186 bytes of RAM. http://vimeo.com/33243761 including the pictures and 1 18 x 34 font. (Watch out for THE FINGER!!) edit Vimeo is still stupid need to go into couch mode to view Kentec 3.5" video.

The same code minus the pictures (arrows, the penguin and moi) but with the same font and basic drawing functions for lines, circles and squares is 15.4K flash and 186 bytes of RAM.

From memory the absolute bare minimum for the library is about 12K flash.

This is a good tutorial for general concepts that can be adjusted for the size/controller you select :

http://www.sparkfun.com/tutorial...

If nothing else, it'll be good to have open as you go thru whichever 'sheet you end up using .

I wouldn't ding-aling around with hot-bar connects
myself ( how easy :roll: are they to remove if needed, w/o damging the Kapton ? ) . How are they to deal with in mass production ?

I use these with FFC connects on the GLCDs, Digikey sells them ( I think it's ALOT easier for protos too ) :

http://www.newhavendisplay.com/i...

Lee, this is the first time I've seen COGs at those prices ( ESP. if they have controllers on them ! ) !
I don't think I'd trust their quality at such prices . Looks like it'll take some hoop jumpin' to get a datasheet from the company . I hope the 'sheets are as good as the prices . Compare to NewHaven and Crystalfontz ( WHY such a big diff. between ones you posted and those I mention ? ) . I doubt you'll really find anything worth dealing with at a $5.00 price in singles having a touchscreen . Closer to $15 - $25 .

You are talking to Mr Scrooge's nephew here. :lol: That would mean I would need to spend money.

Just plain ol' Studio 4.18 and winAvr. You can get the code from circuit idea in the link I posted above for it.

CV2 should have support for a few TFT LCD driver shortly if not there already but I could not run it in the demo version like the nonochrome types it has drivers for.

Off to an ARM seminar now, I'm trying to port the code to a faster machine. Ahhh if only C was really portable... :wink:

Follow up: Still confusing, but here goes...

Varitronix has been around; we've used them for both 7-seg and character LCDs; quality should be OK I'd think.

A chart:

==============================================================================================================================================
DigiKey 	Varitronics		Price 1		Price 100	Drawing		Datasheet	Type	Resolution	V.Area(mm)	Controller	Cont. DS?	Interface
153-1146	COG-C144MVGI-08		4.70		2.94		y			n		CSTN	128x128		28x28		S6B3306	Samsung  no		I2C (?)
153-1147	COG-C144MVGI-03F	5.00		3.13		y			n		CSTN	128x128		28x28		S6B3306					SPI (?)
153-1145	COG-C144MVGL-01		5.00		3.13		y			n		CSTN	128x128		28x28		UC1697A	UltraChip Yes	8-bit (?)
153-1144	COG-C172MVHC-04		5.40		3.38		y			n		CSTN	128x160		29x34		UC1698V UltraChip Yes	I2C (?)
153-1143	COG-T177MXHA-02		8.60		5.38		y			n		TFT		128x160		28x35		ST7735	Sitronix  Yes	I2C (?)

			COG-C144MVGD-04 										y		CSTN	128x128		25x26		ST7687S	Sitronix  Yes	8-bit
			COG-C177MVHS-06 										y		CSTN	128x160		28x35		ST7669V	Sitronix  Yes	8-bit

The first lines are summarized from the DigiKey offerings; the last two are from the Varitronix Web site.

--NOTE THAT VARITRONIX DOES NOT SHOW THE EXACT MODELS THAT DIGIKEY STOCKS.
--Note that there are no datasheets for the DigiKey models. The "drawing" lists the controller.
--The Samsung controller has no datasheet to be found with a quick Google search. How in the heck, then, is one supposed to purchase those models from DigiKey and have any hope of interfacing?!?
--While I listed the Interface as gleaned from the drawings and datasheets for the displays, both the Sitronix and UltraChip controller datasheets indicate a variety of interface options. It varies a bit from controller to controller but might include 4-bit, 8-bit, 4-wire, 3-wire, and I2C.

At the $5 price point, $3 in modest quantities, these displays are attractive to replace a 2x8. You'd get more display in the same size and could add features with the color.

Other apps might use a 4x20 character LCD. The big ones are 116mm wide. A 4.3" LCD, PDA-sized, would do nicely. The price point there is $19-$25.

But I need to crawl before I can walk. UltraChip here I come...

Coincidentally, I'm also looking at working with these small Varitronix displays. I sent an email to their US office this afternoon, and promptly received a response with the datasheet for the COG-C144MVGI-03F. Not sure yet if I can share it with you guys, but I did at least want to point out that they seem to be very responsive to requests.

My board uses the SITRONIX ST7735 and YES I have the datasheet. Have you contacted Samsumg for the datasheet?

The chip is EOL so you may want to reconsider the chosen display

Having trouble matching part numbers from the varitronix web site, so I emailed them. The sheet I have shows a chip ST7687S, so I googled and found a datasheet for that.

I think I'll design for these rather than the $20 nokia knockoff I have.

Certainly you can find a datasheet for that controller. I asked about the Samsung on the $4.70 model...

OK---but that isn't the datasheet for any of the models sold at DigiKey. See my chart above. The drawing files list the controllers that I posted.

More mystery: The 153-1144 COG-C172MVHC-04 above, in the drawing file, shows pins for XL, XR, YU, YD. Those aren't listed in the controller datasheet. Shoulds like touch-screen pinout to me. How can one tell without the datasheet for that model?

Sure does and what more you can get a datasheet for the controller. Before you get one make sure you can get the connector for it.

I got a sample from a company and got the LCD working well however THEY can't get the 4 pin connector for the touch panel and the people I have contacted want to know how many tens of thousand pieces I want.

edit the controller has no idea about touch screens, they are a stick on addition to the front of the lcd.

I don't think so. The datasheet has quite a lot of information, including timing diagrams for communication, but no indication of how to communicate with the controller.

I should be getting a phone call from the US sales office next week. Looking at the Varitronix website, it looks like they do a lot of custom work, and have a few general purpose models like the ones we're looking at. If the Samsung controller is EOL, then I expect Varitronix has another part that will replace it.

I'm also curious to learn a bit more about assembly with these displays. My understanding is that the part is soldered to the board with a "hot bar" machine. Does anyone here know if these are very common among contract manufacturers?

One thing I noticed... These displays are transmissive, which leaves me with the impression that the models lacking a backlight (e.g. the COG-C172MVHC-04) will need to have one added. Does anyone else know more about this?

A little more expensive than the price you want, but here is another option (I don't think I saw it in this thread yet)-
http://www.mouser.com/search/inc...

about $12 in sigles, easy to mount, easy to use, gives a lot more display options than a text

I have been using it with various micros-
http://www.mtcnet.net/~henryvm/5...

my new board in progress (I'm starting to hate breadboarding, and cheap 'real' boards are now affordable)-
http://www.mtcnet.net/~henryvm/5...
http://www.mtcnet.net/~henryvm/5...

I transfered this project to a pic24 (can I say tha?), most C code reused of course. I make my own fonts with a program bmfont, then 'process' the data to a C file via a Rebol program/script. Although there is probably code out there already, I made my own graphics routines.

With the LPC1114, I was running the SPI at max rate with no problem (I think 24mhz). A backlight can also be sandwiched behind the display. With 8k ram, keeping a display 'page' in ram is not a problem.

very easy to work with and I believe CV/Pavel recently added support for the controller in the latest update.
they are also on the atmel ATXMEGAA3BU-XPLD board if you want to try one out easily as it has a simple menu UI demo and code similar to what you describe. :roll:

Varitronix just emailed me a 26 page Pdf for the COG-C144MVGI-08. Also a page of code to initialize it.

Looks like it has a samsung s6b3306 controller. Googling that gets me lots of Chinese, besides a link to this thread.

Heh! I just noticed that AS5 looks just like ASS - coincidence? I think not.

Anyway I've been looking at these inexpensive graphics displays for years and it seems all of them are discontinuations for some recently dead cell phone, thus you can't get one and learn it and put it in something before it is unavailable. Now I'm beginning to wonder since the Mouser parts shown seem like they are at least five years past any cellphone that primitive so maybe they are making them for just for the small market that would now use these sorts of things.

If you learned the HD44780 years ago you can still be using that knowledge, but what about these cheap graphic displays? Is there a standard protocol like HD44780? Any comments on how permanent (in the market) these are?

Pretty much anything that has a smallish front panel (2.8" - 4.3" pretty standard, have used a 7" panel) with switches and indicators can nowadays be replaced by a touch panel.

A large security company around the corner from me seems to have replaced their mylar type panels with touch panels. So it's not just the "mobile phone scrap screen" one can use but many companies supply standard size displays.

The basic graphic libraries (including text fonts etc.) can be used with all displays but the hard metal code varies with each chip manufacturer. So that bit (3 functions) needs to be customised. 8 bit and 16 bit modes are pretty much the same for most displays, SPI mode seems to vary wildly with each type of driver.

Not much visible difference with 8 bit and 16 modes with an AVR, it may make some difference if one has a chip with 16 bit ports.

Several Arduino examples floating around too for the "pot heads, baby talking people" :lol:

Better keep this separate.

I got some of the examples going, now I think I can sort out printf.
http://knowledgebase.nxp.com/sho...

But it would be nice, say, to know how to write 8 bits to a port. I know trivial if you have done it before. :evil:

It seems that I need to stay away from the "semihandholding" mode of the IDE. I want to be able to just include the chip's header file and be able to access everything inside the chip with "normal" C. Don't want to include and have in front of me a zillion files....just in case some code is required from there like the getting started guide says for Code Red V4.10

Hi All--

What is the best way to share large PDFs?

I spoke with a sales rep from Varitronix today, and got the go-ahead to share datasheets for the COG-C144MVGI-08, the S6B3306 controller, and also some initialization code.

I also learned a little more about the EOL designation on the S6B3306. When I asked about this, the rep said that they learned about this change not too long ago, but don't expect it to be a problem. They currently have an inventory of about 500,000 units, and expect this will last for perhaps five years. By then, there should be a replacement part available (though obviously some small changes will be required).

The FFC cable is meant to be soldered to the board using a hot bar. I've asked how common a piece of equipment this is, and the rep is going to get back to me once he's talked with the guys at the factory. I'll let you know what I find out there.

I should also be receiving some documents shortly with pointers on integrating these displays into a design.

I'm going to try uploading the PDFs here. Attached you should find the datasheet for the COG-C144MVGI-08 and the initialization code.

Trying to upload the datasheet for the S6B3306 seems to result in an error. I'm going to try adding it in another reply.

Edit: That didn't work... I think it's too big. What's the best way to share it?

As I said above.. :) 2M is the max size. There are files sharing sites I think. Don't know why Varitronix doesn't put them on their website. :?

Not too fond of the GLGD cable getting soldered to the PCB, I much rather a FPC connector like all the other displays I have used.

The init is not the "usual" style. I'll see if I can add it to my library. I wonder if that chip is compatible with some other chip, a few of them are.

Hmmm--make a .ZIP and see if you get a large compression ratio?

[NB: Given all the details that y'all have pulled out of Varitronix, I'm getting leery of doing a design-in of one of these displays into a production app. Next year for a subsequent build I may not be able to get a model with the same form factor/pinout/connector/controller. New board and new firmware/driver every board build? Sounds onerus.]

Just need programming info for that S6B3306 or equivalent and we'll be well fixed for displays.

?? Why are you all fixed with the small Varitronix displays? The price only? :)

There seems to be an overabundance of display around from other (more stable??) suppliers.

How about Hantronix http://www.hantronix.com/page/in...
Newhaven http://www.newhavendisplay.com/i...

http://www.newhavendisplay.com/i... no touch panel

kitronix (a "spammer" here at times) http://kitronixdisplay.en.ecplaz... are even distributed by Farnell but I'm sure you will get them cheaper directly. I'm playing with their 3.5", 4.3" and 7" displays currently.

'Cause they're cheap. Some of the others cost more than the target price for the gizmo;)

Pretty much. The $5 price point, in qty. 1, from a mainstream supplier and mainstream manufacturer got my interest.

My misgivings are given earlier in the thread. But indeed I may skip the SB controller and look more at the other models.

For me it's the price and the size of the unit. I am looking for a colour display with about 1.5" viewable area and less than 3 mm thick with a backlight. I feel like these should be super common--basically the old "cell phone" size--but for some reason I've had a really hard time finding them through the usual distributors.

If Varitronix has a healthy supply of the Samsung chip, I'm not too worried about a 5 year timeline for building around a slightly different display. By then, my current product will already have been replaced by the next version.

Has anyone got a datasheet for the COG-T177MXHA-02 Display? I send a mail to Vatritronix, but they did not respond :( Please PM me or something, I can provide some web/ftp-space for the Datasheets if needed.

I have the data sheet, the people at Varitronix may still be on holiday mode. I can email it to you as I can't post it here because it exceeds the 2M max.

I joined the board here just to get in on this discussion.

I need a VERY small LCD display and the Varitronix ones fit perfectly (and it is stupid cheap). However, there is clearly some debate over the controller etc.

The datasheet for the COG...03f, which on digikey is indicated as serial enabled, calls for the S6B3306 chip. So I got the datasheet for that from here (thanks crwper!) but it clearly indicates that it is a controller for grayscale LCD's. Digikey lists this display as color.

I can find nowhere to adjust the RGB values.

Also, it appears to have a 16pin connector with a .8mm pitch. Has anyone found a connector that will work with this? Soldering directly to a board makes me nervous. I can't seem to find a Zif connector that matches the pitch and the layout of the ribbon doesn't make sense for a Zif anyway.
