ws2812 vhdl problem
Hi there, I tried to run vhdl code from https://github.com/trobanga/ws2812/blob/master/ws2812.vhdl The strange thing is that timings are not met. As described in code, i connect 50mhz clock to the ip block. Can someone give me a hand with this and test vhdl code? Results
the actual problem? As a "new" in VHDL/FPGA I was almost sure I did something wrong implementing ws2812.vhdl file. I expected 800khz for driving WS2812B leds. Once again - many thanks! Your responses confirms that ws2812.vhdl doesn't generate 800 KHz pulse. PS. ws2812.vhdl file is not mine

LED controlling protocol like WS2812 for more colors
where I can control the LEDs individually, but also have more than 3 color channels like with e.g. WS2812 or the 4 with SK6812. I would like to control at least 5 channels (RGB + warm white + cold white) but in the best case I would want a protocol that can control even more channels (RGB + warm white
There is the ws2811 led driver chip. You can attach any led you like and cascade as many as you need. Otherwise I see no other solution beside a discrete build. Take a small microcontroller and an led driver like the

Using WS2812B with a dsPIC30f4013 µC
Hi there, I'm doing a project which uses WS2812b addressable LEDs, but I cannot figure out how to use them. I want to try with only one LED at first then the idea is to use 16 LEDs to make a 4*4 matrix. Obviously, I already tried to look at
understand it). Could you please explain to me how it works? How to send the RGB (GRB in the case of the WS2812b) values for one and multiple LEDs? Thank you, P.S.: If you have any datasheet other than the one made by "www.world-semi.com" I would appreciate.

STM32 Changing PWM Duty Cycle in interrupt handler
I am trying to control WS2812 style LEDS. When I looked at the protocol, I noticed a short high, long low signal is a zero and a long high, short low signal is a one. So, I got the idea, such a signal could be generated by
BlaatSchaapArchive/LEDcontroller That told project is kinda messy, so I started a new project, extracting the WS2812 code into a library. The library can run on the original STM32F1 but also has support for the Nordic nRF52 series: https://github.com/a-v-s/libws2812dma

Programmable controller for ws2813 led
ws2813 led is ws2812 updated version,it has dual-signal wires version , signal break-point continuous transmission,i want to control it by arduino ,who have the code for it?thanks. ws2813 led datasheet
There is suppose for it in https://github.com/cpldcpu/light_ws2812 Looking at the notes, any WS2812 implementation could control a WS2813 with minor modifications (longer reset pulse)

Custom ESP8266 Board unable to connect
Hello there I have made a custom ESP8266 board with which I want to operate WS2812 LEDs with WLED. I have received and assembled the PCBs and wanted to upload the blink sketch for testing with the Arduino IDE. However, I get an error message in the console that no connection could
