3.5" Color LCD code example

I agree also, its semms a steal. I ordered 3, received them all in good order and time. now to find a project for them, hmm....

Anyone done anything with this LCD yet? Mine is getting dust.

I did something with it, only with an avr and Bascom.

Shouldn't to hard to port to pic

I left all 3 in the nice bubble wrap so the dust is staying off. Actually I would love to just get 1 wired up to even start playing. But so far that has not happened. Maybe we need a workshop thread for this thing. Maybe something like an agreed upon uP and bunches of shared knowledge?

Not gonna lie here, really just am not sure where to start with the beast. I guess uP would be a pretty good place to start.

I feel the same for the LCD. Big with many connections, don't know where to start either.

Also the 3.3 is also setting me back. Would be my first on 3,3 Volts.

Wow, very interesting.

I'm a flight sim enthusiast and plan on building a panel, soon. I'm still debating between using a full size LCD monitor with an overlay panel, or going with multiple small LCDs.

The nice thing with the monitor is that you can get a 19" for under $100 and can have several instrument displays on it; more economical than small LCDs at current prices. And the monitor can be driven directly from the PC at HD quality graphics.

Example panel; a 19" monitor on the left could extend under the 3 smaller dials and a 15" monitor would be sufficient on the right:



As much as I'd love to PIC-my-ride, it's still not cost-efficient yet.

Hi, Thanks heaps
If I do look into a gfx LCD I'll probably begin with this one.

The circle drawing routine needs to check if the value for radius is less than 3.
If it is allowed to draw the circle too small it messes up the display,
and also addresses the screen buffer out of bounds, potentially crashing
if either you or the display software isn't checking bounds.
