First sorry for my poor English. I want to simulate the WS2812B chip in Proteus but there is no available component or part related to this device in Proteus (neither WS2811 nor 5050 smd LED). I read the datasheet of this device (https://www.adafruit.com/datasheets/WS2812B.pdf) but unable to create the circuit to generate the similar waveform. Anyone has any suggestion to this? Thanks in advance.
