hello
from my understanding , analogwrite() is using PWM pins so it's an analog emulator . i also found guidelines for using low pass filter that will turn the PWM signal to an actuall analog - but it comes with delays and noise that i seek to refrain from .
am i missing an actual analog output pin that receives a value and produces a spectrum of voltages between 0 and 3.3V ?
thanks
