可以參考 W 401 C18 workshop 教材的第四章，那裡有詳細的 Union & Struct 的說明。

我也使用PIC18F6722
typedef union{ unsigned char Byte; struct{ unsigned SOF1:1; unsigned EOF1:1; unsigned SOF2:1; unsigned EOF2:1; }bits; }UART01s; UART01s Uart01; //--------------------------------------------------- //UART //--------------------------------------------------- #define Uart1_Byte Uart01.Byte //--------------------------------------------------- #define UART1bt_SOF Uart01.bits.SOF1 #define UART1bt_EOF Uart01.bits.EOF1 //---------------------------------------------------

謝謝! 因為我用別種C可以用我提出的方式宣告,程式比較容易閱讀,修改也很容易
