So, theoretically you could hook up an LCD with your own controller and have a custom arduino Screen!

[Nick]

true, but that's kinda stupid since then you have an lcd display, so you could better use it as screen for you arduino itself. The framerate is only 10~20 fps due to speed of communication, so it(-'s not that fast either

now lines, rectangles, filled rectanlges, ellipses, filled ellipses, text and variable printing works,  so that's already nice
colors wotk too (not for text)

Err, how is using an lcd with a small display controller any different from using it directly on your arduino? You don't have the IO or the ram to directly drive it that directly. Display controllers give you a serial control of the LCD and have internal screen management.

[Nick]

but my "screen" works in a software environment on my PC. it is jst a program running tan interprets the sent commands from the arduino through the serial port (usb) and displays it on the screen with a resolution you can choose yourself.

So you don't have a physical screen...

[Nick]

Update! the virtual screen is published on my website, but i'm still working on it. I'm adding a command prompt so you can send commands from the pc too, that saves a lot of time and a lot of data that will not have to be sent.

and a little video of a simple project with arduino, just to get into the coding

I don't understand much how this works, but basically the small lights turns ON when you move the blue lightning towards them?

[shmibs]

he is using analogue input from the controller to increase/decrease the voltage in the section on the right. as the voltage increases, the light on the bottom gets brighter, and, at a certain voltage, power is able to flow through the resistor that connects to the next light. this process is repeated, so that, as he pushes the joystick forward, more light up and, as he pulls it back, fewer do.

or that's what i think is going on, at least.

[DJ Omnimaga]

Oh wait that's a joystick lol. I didn't notice, since the base is so small.

[Nick]

yep that's it it's pretty simple, one of the most basic things you can do with it, but i saw a lot of the same project using 1000 if statements, and it thought there had to be a different way of handling this, and there is..

but the ay schmibs told it it must be possible too, now i do it completely with code, but somehow with some transistors and stuff i might be able to make the code smaller, i'll take a look at it

[DJ Omnimaga]

Ok good luck and nice you found a more efficient way to do it. Glad to see more people into hardware, especially arduino stuff lately

[Nick]

here's a  video about my software-screen: the virtual arduino screen! it's a software driven screen for the arduino, using serial communication.

Very Nice!
