The previous section introduced the WS2812 driving method. Based on this, we can design a variety of interesting applications. First, let's take a look at the WS2812 light strip displaying a rainbow.
1. Limiting filter method (also known as program judgment filter method)A. Method:Based on experience, determine the maximum deviation value allowed for two samples (set to A).Each time a new value is
The input of this circuit is 220mV AC. I don't understand what the subsequent circuit does and what the P and N are at the final output. Can you help me analyze it?
