Just saying hello Started by MichaelaJoy Yesterday at 6: Articles Top Articles Search resources. I’ve attached a copy of the display. Given that data must be read from a memory internal or external you can see that it’ll take a good 4 cycles per 4-bit write. Sceadwian Banned Feb 8, To participate you need to register. Haven’t checked the display but seems like its controllerless.

I have seen boards similar to this one, that have traces for, but do not include the Datashet, even without drawing anything on screen, printing fonts, your micro will be too busy just taking data from lc97401, and sending ld79401 to the display. I’ve attached a pdf from the manufacturer. There may be too much effort needed to get it going.

The larger LCD you posted has no such controller.

SRAM usually k, 32k x 8, very cheap and common a crystal oscillator, and thats pretty much it. When I was talking about a “controller,” I was thinking of a chip to handle fonts and graphic placement. The display calculated and displayed, altitude,elapsed time, balloon temperature and rate of climb as a bar chart.

The SED is somewhat limited, often used for that displays’ slighter smaller cousins. Media New media New comments Search media.

A PIC 16F provided all data input and display format. So, clocking in data across a line, then moving to next line before flying back to the top, if you draw a pixel in one location, unless you draw it again on every frame, it fades, so it require constant refreshing, usually at around Hz.

Sceadwian Banned Feb 9, I know this board includes four, LC’s and three, LC’s. I believe in general the term ‘driver’ in the context of LCD’s refers to the pixel drivers, which are indeed just giant shift registers that work on positive and negative voltage, and the term ‘controllers’ are used for higher functions such as refreshing, addressing, text generation, window-in-window, cursors etc.

The LC and LC chips have data sheets on the web. I recently developed an instrument package for one of my hot air balloons using a 64 x pixel display with KS and KS controllers. So whilst any micro attached to these has to ‘draw’ text, essentially the LCD has an inbuilt controller – albeit with limited functionality. It took about lines of code in assembler, much of which datasjeet of graphics and fonts data tables. All that said, despite the cost of a controller IC, they don’t actually require much in the way of external circuitry.

You must log in or register to reply here. It appears to require an external driver. Sorry for the pesimistic dagasheet post. I said ‘in general’ because the two are often interchangable and have caused me headaches in the past when researching how to drive these things.

The micro controlling it treats the LCD is memory, writing to address locations.
