+** ChibiOS/RT port for ARM7TDMI AT91SAM7X256. **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an Olimex SAM7-EX256 board.
+
+** The Demo **
+
+The demo currently just flashes the LCD background using a thread and serves
+HTTP requests at address 192.168.1.20 on port 80 (remember to change it IP
+address into webthread.c in order to adapt it to your network settings).
+The button SW1 prints an "Hello World!" string on COM1, the button SW2
+activates che ChibiOS/RT test suite, output on COM1.
+
+** Build Procedure **
+
+The demo was built using the YAGARTO toolchain but any toolchain based on GCC
+and GNU userspace programs will work.
+The demo requires the patcher uIP 1.0 stack, see: ./ext/readme.txt
+
+** Notes **
+
+Some files used by the demo are not part of ChibiOS/RT but are Atmel copyright
+and are licensed under a different license, see the header present in all the
+source files under ./demos/AT91SAM7X256/at91lib for details.
+Also note that not all the files present in the Atmel library are distribuited
+with ChibiOS/RT, you can find the whole library on the Atmel web site:
+
+ http://www.atmel.com
+
+The uIP stack also has its own license, please read the info into the included
+uIP distribution files.
