channel.h File Reference

Detailed Description

ESP32-P4 Parallel IO (PARLIO) LED channel.

This driver uses the ESP32-P4 PARLIO TX peripheral to drive up to 16 identical WS28xx-style LED strips in parallel with DMA-based hardware timing.

Key features:

• Simultaneous output to multiple LED strips
• DMA-based write operation (minimal CPU overhead)
• Hardware timing control (no CPU bit-banging)
• Runtime-configured for different channel counts and chipset timings
