Backlight:  letter to nintendo.. yes or no?  haven't sent yet

did code for size reduction

Hello, my name is James and a group of my friends are developing a calculator the succeeds in all spots others have failed.  While brainstorming I cam up with an idea for a back-light for the calculator. (specifically one that is manually turned on and off)

One of the members of our group had the brilliant idea of using a back-light like your Gameboy Advance SP (big fan by the way).  Doing a little research got me nowhere so I came here to ask about how you made your back-light.

Could you inform us on the specifics of how the back light is made, or where to buy something similar.

They would probably say no. Nintendo's a lot more eviler than TI. (Especially with the Wii)

I'd like to suggest a micro SD or an SD card slot for the EZ80, and perhaps an Micro USB as well. Personally, I think an OS written to take advantage of the EZ80 would fare much better than porting Knight OS. I also think having 256 colors and at least a 320X240 resolution would be nice. On an unrelated note, this topic has really exploded hasn't it?

because its a good idea

i refrsh that page every 10 min

Hmm I am a little worried about the devboards, is that just for testing or is that actually going to be in the calc cause $179 is a little expensive don't you think, and that's even without the case, buttons and LCD! I don't think there is a market for $250+ calcs...
Not to offend but I am doubting if that will work...I was thinking about manually made PCB's altough it takes far more time, it is far less expensive. maybe we could clone a Begle..ehr something mX?

Edit: I think the eZ80 could handle colors but we want this to be the cheap alternative to the ARM right? so I think greyscale would be better, 16 lvl or more would be fine

Dev boards are always high priced, since companies want some profit for giving people tools to create products.
Of course, the FINAL product will be way cheaper.

There were actually $1000+ dev boards for nearly the same stuff as the BeagleBoard, but the product itself is much cheaper.

i think 256 color spectrum is unnecessary. remember, this is just a calculator. what would you use 256 different colors for? i'm thinking that using a byte, you can use 4 bits for intensity and the other 4 bits for color specification. that way you get 16 colors at 16 different shadings.

i really don't have any expertise in this field though, so maybe what i just said isn't possible. regardless, i'm thinking 8 or 16 colors would work.

That is 256 colors, just so you know
