Hello,
I want to design an electronic board with a microcontroller which can communicate with some external flash memory (approximately 16 mbytes to hold some graphics). The microcontroller has to be able to communicate with a color 1.5" tft LCD which can display at minimum a collor depth of 16 bits/pixel.
I should be able to design my own controls. For example, I would like to design a drop down list box with unique features in terms of graphics. Special backgrounds are shown when the drop down is down with special text fonts as the items in the list and so forth. The system should also comprise touch screen capabilitites. Also I should have a way to store atleast 4 sizes of a particular font. I also should be able to download into the flash memory pictures, icons and patterns and be able to execute their display with some C function that would reside in the microcontroller. Also, the display should be able to do wallpaper and watermark. The objective of this is to have a miniature microcomputer system which would allow me to develop any application in C inside the microcontroller.
Here are my questions:
1) What is the best microcontroller to use for this?
2) Should I use Linux, WCE or a proprietary kernel that I will design from scratch?
3) What would be the approximate costs if the Linux/WCE option would be considered?
4) The above has to fit in a PC board of a maximum size of 1.5" x 1.5" !
5) Can the above system be built using parts that would not total to more than 8$ (TFT LCD excluded) ?
6) Approximately, how long would it take for an engineer to develop the above specifications if I were to subcontact this to a company?
Sincerely yours
Rob
