大大前輩
我很想一下子就變的跟你們一樣,可是剛進公司初學快一個月,還弄得不太董,所以才會把Time1和sofe time寫在一起,假如這次測OK,就還會把sofe time改掉,不好意思喔...^^!!! 那為什麼我會在這 ADconverter1: call ADloop_time call ADloop_time call ADloop_time call ADloop_time call ADloop_time call ADloop_time bcf STATUS,RP0 bsf ADCON0,GO 加這麼多本是想說,因為調時,怕他時間不夠久,說不定在調的瞬間,就已經與第一次一樣,才會加這麼多的說.. 另外想問這是什麼意思看不懂,拍謝拉...^^!!! movlw LOW (.65536 - Countms) movlw HIGH(.65536 - Countms) 是連LOW,HIGH都搬進去暫存器嗎... 真是麻煩你們了,以後請大大們多多指教小弟,感謝您....

TIMER1 + SOFT DELAY 看的 眼花花的
 很難看出你想表達什麼 , 我在想一個月後你自己是否還看的懂自己寫的程式  Attach file: Link only for registered users

依照大大們給的提示小弟修改了,照理應該會有結果了..怪^^!!!
-------------------------------------------------------------------------- 你很煩耶 ! 程式落落長 又不曉得你要問的重點是什麼?? 可不可以程式另外上傳, 不然光整理又要老半天....... OR MAIL TO ME DATA SHEET 多看一點 , ADC 的取樣時間只要 12 uS ; 太多無益 (TABLE 12-9: PIC12F675 A/D CONVERSION REQUIREMENTS) btfsc ADCON0,GO goto Wait1 movlw ADRESH ; ----- XXXXXXX movf ADRESH , W ; -------VVVVV ADRESH 不用清除
