Скачать или смотреть 🔥 PYNQ-Z2 + Rotary Encoder + FSM + NeoPixel 4×4 – FPGA RGB Controller 🔥

A mini-FPGA project, but the quality is not mini at all.
I built an RGB Controller running on PYNQ-Z2, combining:

✨ KY-040 Rotary Encoder - rotate to select the effect
✨ 4×4 NeoPixel WS2812 - full color RGB LED, smooth animation
✨ Rotary Decoder + WS2812 Driver pure Verilog - write all standard 800 kHz timing

This project is mainly to practice real-time digital design skills:
● Encoder signal processing, anti-noise, debounce
● Precise rotary decoding
● FSM design to control RGB effects
● Create standard pulses for WS2812 on FPGA (0.4 µs - 0.8 µs extremely tight)

💡 The result is an LED panel that runs extremely smooth animation, turning any button change the effect.
