PWM control of LED Driver
Posted: Sat Dec 30, 2017 10:28 amI'd like to use my nodemcu esp8266 to control the PWM of a LED Driver but not having any luck so far. The LED driver supposedly only requires 2V but it is not dimming with esp8266 in Arduino. I'm using D1 (GPIO5) and confirmed it will dim a small led. I also tried an Arduino (5V) and that dims the led driver. So wondering if perhaps I just need 5V or is there something else about the esp8266 PWM that could explain the problem?
The led driver chip is XLSEMI xl4001e1
