Homebrew device with iPhone aspirations

Can you make an iPhone out of an AVR? No. Can you get a surprising amout of functionality out of a humble 8 bit processor and a cheap touch LCD? Yes.

Fake. the pac-man image moves around independently from the thumbs and from the screen edges. most of the demos look superimposed. Looks faked to me. I work with 8-bit PICs for 12 years and I'm almost certain there is no way to get that kind of performance out of one even using assembly language. I could be wrong but I'm going to have to say this is some kind of hoax.

@neimado Not fake. Honest. Grab the code from sourceforge and build one if you don't believe me. Other folks have and they get the same results. There is a kit coming very soon or I can send you a pcb if you like.

I agree the pacman does look a bit odd but it is just overzealous motion compensation in the encoding of the video not something more sinister.

just one simple question, how much cost to create this product ?

[rossumur]

@FOODFORTHEBEES About $25.

I'm driving an ILI9325 QVGA display with a PIC and having problems with the voltage controls at 3.3V.

The only way I can get my screen to come on is to connect a 9V PP3 battery to the backlight! I'm sure it should be possible to get the LCD to generate the necessary voltages, I just don't know how.

Could you share your working power control values (address values 0x10-0x14)? Mine are all set to zero!

Love the post, btw!

[rossumur]

@blinky465 check the code on sourceforge under microtouch for ili9325 initialization. Power control values of 0 will give you a nice clean blank screen ;-)

Wow! No other words for this!

Can I zoom images? It is possible?

plice?

[LJDEST5]

awsome project. i have always wanted to build a similar one but i didnt know which microcontroller would fit. can you please send me the schematic drawing, please.

@neimado,

Go to ticalc.org and check for what some guys do with their graphic calculators (specially Motorola 68k 12Mhz based ones - TI89, Ti92, PLT200) ...

[treborrrrr]

How the f... I'm sitting here with a 320x240 display connected to a PIC18F4550 running at 48MHz doing nothing but blasting out alternating red, green, blue frames and it's not even /close/ to being this smooth. Sure, it's done in C but c'mon, it's just changing the value of 2 ports when changing colour and the rest of the time it's just twiddling a clock pin. Gah! *sigh*

Wow!

would you mind putting the sourceforge link up in the vid description.

You are absolutely amazingI would love to look at your code. I will proceed to look through the comments fo the link.

Amazing stuff, I'm off to the site now! Also, what music is this?
