The scenario
A developer implementing manual LED brightness control via a potentiometer on a PIC16F887 needs a control flow for reading ADC and updating hardware PWM.
What is in this drawing
Read the decisions behind it.
01
Map 10-bit ADC to 8-bit duty cycle
02
Update PWM only when ADC change exceeds dead-band threshold to reduce flicker
Suitable for single-channel LED dimming in embedded systems using a potentiometer and hardware PWM on PIC microcontrollers.
