I've got a "Nokia 1100" LCD, which (unless I be mistaken) is based on PCF8814, whose digital I/O range is (1.7 .. 3.3) V. The question is: is there an easy and safe way to connect it to an otherwise 3.3 V (+/- some) circuit (as in: one interfacing an SD card, or having an Arduino as its core, etc.)? (Will a few diodes suffice, for instance?) Also, the pinout for the LCD (e. g., ...

Hi, all, My shiny new (to me) HP 89441A has an analogue video output, but none of my LCD monitors can sync to it--one says "out of range" and the other two just sit there sulking. So I think that its vertical sync is too fast for them. Any recommendations for LCD monitors that can handle Y2K-ish vertical sync rates? Thanks Phil Hobbs -- Dr Philip C D Hobbs Principal Cons...

I just discovered something weird and something slightly annoying about this camera: This canon powershow hs sx50 mirrors the lcd screen when it's rotated towards viewer. It's really strange... I proved this by holding up a card with letters on it, when the LCD screen is "bend/twisted/rotated" suddenly the camera will mirror the LCD screen like you are looking in a mirror ?

How much state do LCD controllers (as in: "those used in monitors") contain? E.g., does the scaler just rely on a single row (or two)? Said another way, what's the delay from input connector (of the monitor) to "visual output" likely to be? And, how much is it likely to vary from model to model, screen geometry to screen geometry, etc.?

Assuming one back-plane to consider , what would be most efficient component-count/least complex discrete/CMOS/74 route , ie not pic/Pi/uC to firstly convert the ex-oring business to proper levels and then the "mapping", output could be linear per digit rather than bcd. Starting with an off-the-shelf commercial unit where the LCD display is driven off a uC, to give a remotely monitorable ...

Anybody know of a good source for handheld enclosures to fit a standard 16x2 line backlit LCD display? Preferably one that also has a 9-volt battery compartment. Plastic is preferred. (Metal is also OK) And preferably one that comes complete with a bezel. This will be for a generic (temporary-use) handheld-type tester for something that runs on an RS-485 loop. So, a place to put QTY-(1...

I just did a high-speed capture of an lcd/vga monitor and it appeared some kind of pattern was showing when the monitor was blinking different colors at rapid speed, though still vertical retraced/synced to it's frequency of 60 hz or so. On the high speed footage it appears there are these wave like almost plasma like patterns... and also ripples can be seen, slightly. What are t

I have a request for a remoted LCD display. Having chased available products to no avail, it's time to honor Bob Pease and roll out the solder. In this specific case, the least parts count approach seems to be 1_Wire as we have that in use already.

I've only once spec'd an LCD display in a product. I recall lots of different issues, criteria (transflexive, transmissive, high temperature, etc.). But, have largely forgotten most of those issues (IIRC, transmissive/transflexive/reflexive have to do with the treatment of the back of the display) I recall response time was sensitive to excitation voltage and temperature. I don't recall ...

Hello, Right now I am computing on a very nice LCD monitor which has VGA as best connection option. (I tried VGA to VGA cables and DVI to VGA cables both work nicely and after the monitor is told to "auto-adjust" the screen becomes crystal clear). The monitor does have some issues displaying this page, it blinks: http://www.lagom.nl/lcd-test/clock_phase.php Not sure if it's a

Obviously has an LCD display, up top. And, likely a smaller one down low (likely used as a touch panel). The two black circles n either side of the "touch panel" looked like they might have been speakers of some sort -- but, I notice a pair of (cheap) headphones hanging on a hook at the left (AND RIGHT!!!!) so not so sure about the "speaker" conclusion. No idea as to what that orange th...

My kitchen's electric oven is misbehaving. After it's been on for a while, it can make a buzzing noise, and its LCD (?) flickers. Eventually it shuts off, resets itself, and restarts with a "Program Cancelled" message. Clearly, its microcontroller knows that it was previously running. This is not like a power-on reset. The buzzing sounds a bit like a relay that's receiving so little ...

In junior high, before my family had a "real" computer, I cranked out many a school report on my parent's Panasonic Penwriter word processor. It was like an electronic typewriter with a tiny LCD display for entering text, but instead of a daisy wheel or something it had four color pens controlled by servos and some limited ability to do vector graphics, I remember doing some really nice-...
