C18 應該沒有這麼強，強到可以支援位元指標功能吧!
RAM 指標都是用 FSR 無法單獨指定到一個單獨位元。

ON C18,
如打算用位元指標指到不同port 時該怎麼寫?? 例如以下, #define LED1 LATCbits.LATC1 #define LED2 LATCbits.LATC2 struct PP{ unsigned *bit_ptr; } LED; void mail(void) { LED.bit_ptr=&LED1; //令指標位址指到LED1位址 *LED.bit_ptr=1; //令LED1(port.c1)LED1 output hi // 以上兩行當然是錯誤啦, 該怎麼改?? }
