And, i using default neopixel lib. Any suggestions, assumptions? And also, in the manual there is some info a...

Re: Neopixel brightness?
Is it the right way, to change just brighness, but not colour:
Code: Select all
color = [128, 255, 128]
brightness = 5 # brighness in % (0-100)
def bri(pos):
global brightness
pos = round(pos/100*brightness)
return pos
result = list(map(bri, color))
print(result)

Re: Reading fan tacho signal frequency?
I want to use my ESP32 also to control the fan speed of my PC water cooling system. I am using LoBo´s precompiled micropython as I need the SSH client for another task in the system. I think I have everything I need, except I don't know how to read the fan speed. I have same problem. Today i made t...

Re: Reading PWM signal using ESP8266? Generating 30 KHz PWM signal? (Updated)
Same class, but the hardware has a different limit -- like Jan said, it goes up to 40kHz on ESP32. The docs you're looking (that mention the 1kHz limit) are for the ESP8266 specifically. Ok, thanks! Didnt know about it. Already ordered ESP32 for my project with PWM. I was thinking about outer PWM-g...
