When it is 100% that brightness regulated signal LED1_PWM, which is dutycycle, at this moment Vin=3.3V*100%=3.3V, electric
Resistance R1 connects with resistance R2, according to：(Vin-Vfb)/(R1+R2)=(Vfb-Vout)/R3, is obtained：Vout=Vfb- (Vin-
Vfb) * R3/ (R1+R2), now minimum by the electric current of LED light group, minimum current Imin=Vout/R4, R4 are R4 pairs of resistance
The resistance value answered.
When brightness regulated signal LED1_PWM is that dutycycle is that the electric current of LED light group is in minimum less than 100% more than 0%
Change between electric current Imin and maximum current Imax, the brightness of the corresponding LED light groups of minimum current Imix is minimum, maximum current
The brightness of the corresponding LED light groups of Imax is maximum.It is thereby achieved that the automatic brightness adjustment for LED light group changes.
