STR710的UART

请教大家一下：我的UART的程序是参考ST网站上的写的，应该没有什么问题吧？但是我的超级终端上面什么也收不到,我用的是UART2，请问还要有其他要设置的地方么？我把我的程序贴上：
#define UART0_Rx_Pin (0x0001<<8)   /*  TQFP 64: pin N?63 , TQFP 144 pin N?143 */
#define UART0_Tx_Pin (0x0001<<9)   /*  TQFP 64: pin N?64 , TQFP 144 pin N?144 */

#define UART1_Rx_Pin (0x0001<<10)  /*  TQFP 64: pin N?1  , TQFP 144 pin N?1   */
#define UART1_Tx_Pin (0x0001<<11)  /*  TQFP 64: pin N?2  , TQFP 144 pin N?3   */

#define UART2_Rx_Pin (0x0001<<13)  /*  TQFP 64: pin N?5  , TQFP 144 pin N?9   */
#define UART2_Tx_Pin (0x0001<<14)  /*  TQFP 64: pin N?6  , TQFP 144 pin N?10  */

#define UART3_Rx_Pin (0x0001<<1)   /*  TQFP 64: pin N?52 , TQFP 144 pin N?123 */
