通信协议 0xfc data 0x00 0x05

eg:16bit数据分4次发送，高位在前

    USART_Tx(USART0,0xfc);
    USART_Tx(USART0,ChartoAscii((unsigned char)(hand_sup_curr_data>>12)&0xf));
    USART_Tx(USART0,ChartoAscii((unsigned char)(hand_sup_curr_data>>8)&0xf));
    USART_Tx(USART0,ChartoAscii((unsigned char)(hand_sup_curr_data>>4)&0xf));
    USART_Tx(USART0,ChartoAscii((unsigned char)(hand_sup_curr_data)&0xf));
    USART_Tx(USART0,ChartoAscii(0x00));
    USART_Tx(USART0,ChartoAscii(0x05));
