Rescaling of values in PBP.

[Acetronics2]

Tray (Value * 0.313)+165

a) (0*0.313)+165 = 165
b) (255*0.313)+165 = 244.8

Since you don't need high accuracy it should work.

Hi,

With PbP ... I'd rather try :

Duty = ( Value * 5 /16 ) + 165



But it's just me ...

might better be PWM = (3.175 * Value ) - 523.875

OR PWM = ( 127 /40 * Value ) - ( 4191 / 8 )

PWM = (( 127 * value / 5 ) - 4191) >> 3

...
