Hello. I was written my program to control ws2812b led-tapes last year, and now i tried to replace ws2812b with ws2811, and its does not work. Why? As i know, ws2811 using the same signals?? And, i using default neopixel lib. Any suggestions, assumptions? And also, in the manual there is some info a...

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)

Is there any way to control brightness of ledlights with oficial neopixel driver? Or mb some forks of it exists (besides LoBoris port)?
Thanks

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...

Thanks. Strange thing. I rollbacked sp2102 driver to older version - 6.7.4.261, and esp32 dont rebooting when i reconnecting inside of my programm now. It solves my problem... But with this old driver version flasher of esp32 isnt work (i sucseed flashing process only with new version of 10.1.8.2466...

Why esp32 restarting after USB connection? For example, if i connect to it with EsPy, disconnect, and after connect with another software - ESP32 will make reboot. Why? I make software to control it via serial port, and in some cases ESP32 is rebooting even after reconnection of my program. I heard,...

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...

Oh darn, I was thinking about the capabilities of the esp32, which can do up to 40kHz.

I'm sorry, isnt esp32 using the same machine.pwm class, in whitch docs written about 1KHz limit? Or i understand smthng wrong?
