Hi,
I have tried some thing on 320x240 TFT LCD with Touchscreen using avr and arm cortex m4 microcontrollers. But what hardware should I use to make more rich graphics, I should be able to zoom in and zoom out on images etc as seen in android mobile phone, cool animation, background clock, wallpapers, themes etc..

Is this much things could be done using a general purpose mcu? Or should I go for any android development board?

Or can any one suggest an approximate hardware requirement for doing some thing like this?
Also can I do this much things without an operating system also?

See this, also you have schematics there :

MikroMedia for STM32 M4 - ARM Cortex

See Video Examples for AVATAR on M3:

You can make anything what you want on ARM Cortex.

Hi tpetar, playing an uncompressed video is okay we can do it, I did the same using an atmega32 and 128x128 color lcd earlier...
But the problem is the rich graphical interface. I need to zoom image using touch, need to move the zoomed image fast around the screen etc etc, it should be almost like an android display which shows icons, even the icons should animate also.. :D

For doing such complicated stuff, I am not sure I can do it with just a microcontroller, may be I need an os like android or some thing else , right?
 

Its possible with the same platform for sure, I just post one example. You can find more examples for this platform, and of course you can do lots of nice things what You mentioned.

Android OS give you more opportunities with softwares. But its more complicated to develop platform.
 
Yeah, but if I am using just a microcontroller then the development and all will be difficult na? If it is android or some thing like that then may be it will be easy I think. what is ur opninion?

Or if we have a small embedded linux board connected with lcd then we can do any thing compared to a microcontroller alone design, right?

It will be cheaper if we buy ready samsung galaxy s2,s3,s4. :smile:

Depends from capabilities of that particular Linux board. Why not.
 
Any way I am in doubt what to select :D
Just want to make some interface almost similar to android, if it is possible without an os and just an ARM controller + a RAM, it is fine!!! :)
