請問一下
我板子是DSPIC30F 4011 我想要有16PIN的數位輸出 我規劃了 RE0~5 & RE8 & RF0~6 & RD0 & RD2 我有把ADC功能先OFF掉(ADPCFG = 0xffff) 沒有用到LCD 以下是我簡單的設定 全設為OUTPUT 初始為LOW狀態 TRISB = 0x0000 ; //RB dir TRISF = 0x0000 ; //RF dir TRISD = 0x0000 ; //RD dir LATB = 0x0000 ; //RB init V low or high LATF = 0x0000 ; //RF init V low or high LATD = 0x0000 ; //RD init V low or high 但外接LED 似乎並不正確 請問是哪邊出了問題嗎?! 謝謝 如果我想使用LCD功能 除了RB7要還給LCD控制外 還有別PIN嗎 謝謝
