STM32 Power shield and Nucleo expansion board (UM2243) for power consumption measurement
LED brightness dimming changes the brightness by changing the LED's on-time. The longer the LED's on-time per unit time, the higher the brightness. In practical applications, it is controlled by changing the duty cycle. It can be seen from the light efficiency conversion characteristics of LED that when the same duty cycle is increased, the brightness increases more at low gray values than at high gray values. At the same time, at low gray values, every time the gray value changes by one In small units, the value of the light intensity increase rate D is relatively large. As the brightness increases, the light intensity increase rate D decreases, and the human eye's sensitivity to light changes also decreases. That is to say, the level jump is very obvious at low brightness. The brightness jump is particularly sensitive to human vision and cannot achieve a flexible effect of gradually brightening or dimming. The principle of smooth dimming is to improve the dimming effect of LED by changing the linearity of LED dimming curve.
