AT91SAM7S64的uart程序。包含完整的uart API 可以完成向串口写数据和接收数据

// This program shows how to work with USART port
// USART0 and USART 1 (respectively RS232_0 connector and RS232_1 connector) returns echo + *
// Notice: Jumper RXDO/DRXD must be in position RXDO
//         Jumper TXDO/DTXD must be in position TXDO

//it's a simple delay
void Delay (unsigned long a) { while (--a!=0); }
