dear 各位前輩~ 我有一個問題想請教你們....這裡有一個數值介於300~3800之間...請問要 如何等比例換算成0~4095呢....我想了很久還是想不出來... gooodfeel

hi,goodfeel1001    假設x介於300~3800 y介於0~4095    則比例換算("長度"比例) (3800-300)/(4095-0) = (x-300)/(y-0)    所以 y = 4095/3500*(x-300)     <> <> >

The first step toward proving things for yourself is to understand how others have done it before!

dear fusung~ 寫得很詳細...我已經看懂了..謝謝您....^______^.... goodfeel1001

更正一下您的 y=4095*(x-300) / 3500 才對喔
