Sample for working with Graphics.spin

Jim Fouch

A while ago (Like 3+ years ) I posted a sample of a motorcycle·instrument display·I designed for my bike. I haven't really done much with it. Don't even have that same bike anymore.

I've had several people ask for the source to see how it was done. I've posted it to the OBEX for all to see.

It shows...

• How to easily assign color palettes to screen tiles.
• Create a grid overlay to see where the object fall into place within the tiles.
• How to get around the double buffering if you're low on RAM.
• How to create a tachometer·type display·by using vector graphics.·
• Create smoothly updating displays by tracking the changes in the data behind the display. (Only change what you have to)

I know it's not documented the best, but most will·be able to see how it works. If you have any questions, please feel free to ask.

It will run on a Prop Demo Board with a simple button wired to Pin 7 pulled high to 3.3v with a 10K resistor. It uses the TV out.

Here is a link to to display running on the actual bike... Link

Jim, this is very impressive! Almost makes me want to add a display to my CRF450R. Thanks for sharing.

Nice work!

Hmmm... you could for example use the background color to indicate problems by turning it yellow - orange - red for overtemp/over-rev etc...

Yep. If the tile was the same size of the area you wanted to highlight.

I haven't tried changing the Tile Palettes after the fact, but I don't see why you couldn't. It would be a lot faster then painting a new box and repainting the contents of the highlighted area.

Also could be a quick way to flash the whole screen. Or even have a day time/night time background/foreground colors.

Thanks for posting Jim,
I have been waiting for "like 3+ years" to see it.
I have been wanting to try it out on on of Tim's·NTSC LCD displays.

Hi Jim,

A great demo, with lots of useful code to copy!
I loved the link, with the audio track as well it felt like being on the bike.
Over a 'ton' too ...
