I’ve attached a copy of the display. The datassheet calculated and displayed, altitude,elapsed time, balloon temperature and rate of climb as a bar chart. When I was talking about a “controller,” I was thinking of a chip to handle fonts and graphic placement. Welcome to our site! It took about lines of code in assembler, much of which consisted of graphics and fonts data tables.
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. Please provide reference to this type of display being used with an on board controller. The LC and LC chips have data sheets on the web. Haven’t checked the display but seems like its controllerless.

Again, sorry for the long post, I got a bit obsessed with LCD’s back in the days of sticking them on ones PC to display pointless information and my mind is stil full of crap about em Edit: I can find links to the LCD drivers, not anything useful for the Epsonwhat are you talking about?

All that said, despite the cost of a controller IC, they don’t actually require much in the way of external circuitry.
There may be too much effort needed to get it going. Thread starter bobledoux Start date Feb 7, So I know it can be done for slowly changing data.
It stores the bitmap in memory, and constantly refreshes the display without intervention from whatever is controlling it. The LC and LC are often driven by a controller, like the Epson to reduce off-board workload.
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 wanted to see a photo of the back because I think the traces are there for a controller and RAM.
The SED F was popular as an onboard or external controller which has been replaced by the S1D internal ram, lower power etc. Started by fastline Yesterday at 8: I’ve attached a pdf datsheet the manufacturer. I’m not trying to discourage folk from using the display, x’s are awesome!
