Hi All ~

1. 8 Bits LCD Panel,256 Scales (Max.),So If You Show The 256 Scales By 256 Steps,Then It'll Show Scale More Smooth,But If You Show The 256 Scales By 64 Steps(Just Same As My Program),It'll Show 4 Scales/Step Until Up To 256 Scales,Because Every Step Have 4 Scales Different,So You'll See More Clearly Split Than 1 Scale/Step.
But In Visual Inspection,People Always Hard To Differentiate The Wrong(Or A Little Wrong) Scales On 1/256 Step By Eyes.So 64 Steps To Visual The Scale Step Is Better By People's Eyes.
If Any one Step(=Any one Scale) Wrong,You'll Find Out Easily On 64 Steps Than 256 Steps.

2. The Test Program Is DEMO And Share On The Internet,So Everyone Could Download It And Put It In You WEB To Popular . It's My Honor !!
