It is such a mundane task, moving data, doesn’t require intelligence, just counters, but at a speed beyond that of most 8-bit devices. The SED F was popular as an onboard or external controller which has been replaced by the S1D internal ram, lower power etc.

I wanted to see a photo of the datashest because I think the traces are there for a controller and RAM. Hi, the KS and KS chipset are both drivers and controllers in one, they have the IO’s and shift registers to control each pixel – but also the field memory RAM to refresh the display.

I have other projects on my list right now so I’ll leave this LCD on hold. Thread starter bobledoux Start date Feb 7, 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.

The micro controlling it treats the LCD is memory, writing to address locations. I know this board includes four, LC’s and three, LC’s. Welcome to our site! 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.

All that said, despite the cost of a controller IC, they don’t actually require much in the way of external circuitry.

I can find links to the LCD drivers, not anything useful for the Epsonwhat are you talking about? There have been a couple of old AVR projects which lc7901 sorry, control these displays directly using external SRAM but given the datashfet they don’t have much in the way of ‘options’.

The PIC was only running at 4mhz and had no difficulty updating the display every half second. You must log in or register to reply here. Does it have an additional controller and perhaps RAM or negative voltage power source?

Potentiometer Questions Started by norbss Yesterday at Blueteeth Well-Known Member Feb 11, Often some delay is required before a ‘end of line’ sync pulse, so say this is Haven’t checked the display but seems like its controllerless.


The display calculated and displayed, altitude,elapsed time, balloon temperature and rate of climb as a bar chart. The LC and LC are often driven by a controller, like the Epson to reduce off-board workload. I’ve attached a pdf from the manufacturer.

So I know it can be done for slowly changing data. So, even without drawing anything on screen, printing fonts, your micro will be too busy just taking data from memory, and sending it to the display. The larger LCD you posted has no such controller. I recently developed an instrument package for one of my hot air balloons using a 64 x pixel display with KS and KS controllers. Click here to register now. 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.
