- Study about microprocessor architecture on ARM7TDMI

Time-line : 12/02 - >  26/02

- Study about MCU AT91SAM7S256 of Atmel( core  using   ARM7TDMI)

Time-line  :  pending

-  Write demo  programming  : +   leds blink.

                                                          + Buttons  controller .

                                                          +serial port , SD-card , interrupt....

 Time-line : pending

- Study about Real  time OS 

Time-line : pending

- Write demo programming using Real time OS :muti-task (button, LCD, Serial, SD card)

Serial port, SD card, Interrupt..
Time-line : 15/06- Finish.
- Mouse connect PC  via usb port
-  .........................................................................................
