用GPIO我想應該是16F629/675吧...去看一下data sheet比較清楚...
1.A/D要關閉...預設是打開的 2.有使用到的I/O要設成輸出..應該會設定吧 3.另外就是小心BANK別切錯了.. bcf STATUS,RP0 clrf GPIO movlw 07h movwf CMCON bsf STATUS,RP0 clrf ANSEL movlw 0Ch movwf TRISIO bcf STATUS,RP0 BSF GPIO,5 BSF GPIO,4

各位高手有個問題在跟大家請教一下，就是假設我現在要Set GPIO Pin的輸出，啟動我下一級的開關，所以我程式目前是這樣寫的 ，
bsf GPIO,5; bcf GPIO,4; 請問一下這樣子可以嗎？ 是否還有更簡潔寫法呢？ 可是我觀察過GPIO的Register的值，都不會變化，這是為什麼呢？希望大家能為我解答一下。 Thk
