3. Typical applications

3.1 basic functions

Two gp7701 are connected in parallel, one A0 pin is grounded, and the other A0 pin is connected to 5V power supply. The upper gp7701 outputs three PWM signals to control the brightness of RGB three-color LED respectively, and the lower gp7701 outputs two PWM signals to control the two channels of cold light and warm light LED respectively. Thus, the panchromatic control of the chip is realized.
