I am trying to get my Ray Wu WS2811 led’s working with FastLED and my NodeMCU ESP32 and I am running into problems with the LED’s flickering like crazy or not lighting up at all sometimes. I have tried many things and can’t solve this puzzle why it’s not working. Could anyone take a look at my setup and see if they notice anything bad?
I am using the most basic code in the fastled example folder for just calibrating the RGB ordering… I changed the Data pin to 12 btw
@Jeff_Sheiman I mean the Adafruit level shifter you’re currently using, as shown in the picture. The 74HCT245 is the only level shifter that is highly regarded around here, as it always works. Here’s a great article on the subject: https://happyinmotion.com/?p=1247
@Jason_Coon I just ordered a few 74HCT125 on adafruit because the 245’s were out of stock. Are they just as good as the 245? Thanks for the advice! Hopefully that does the job. I think I need to buy an oscilloscope. Does everything else look to be in order though?
