从OURAVR上购得一块AT91SAM7S64的开发板，添加如下At91sam7s64
开发板原理图。原理图画得很倒塌，有好几处问题，初步调试：
1. U5 RC-8025: Actually Part Number is RX-8025 (real time clock);
2. Use 5V power supply (or USB)for the system;
3. RS232 connector pin2, 3 reverse;
调试时，可以使用WINARM上带的程例编译，要修改board.h：
#define SW1_MASK (1<<17) /* PA19 / PGMD7 & RK FIQ 13 */
#define SW2_MASK (1<<18) /* PA20 / PGMD8 & RF IRQ0 16 */
#define SW3_MASK (1<<19) /* PA15 / PGM3 & TF TIOA1 20 */
#define SW4_MASK (1<<23) /* PA14 / PGMD2 & SPCK PWM3 21 */
#define SW_MASK (SW1_MASK|SW2_MASK|SW3_MASK|SW4_MASK)
#define SW1 (1<<17) // PA19
#define SW2 (1<<18) // PA20
#define SW3 (1<<19) // PA15
#define SW4 (1<<23) // PA14
