PaperDIY Assembly Kit (M5Stack) · avance · Réduisez la latence d'affichage en exploitant le mode partiel du pilote parallèle 8 bits.
Hardware: Assembled PaperDIY, ESP32-S3, logic analyzer for 8-bit bus. 2. Setup: Initialize parallel bus at high frequency (80MHz), ensuring CS, WR, RD lines are synchronized. 3. Code: Implement a diff function between two 16-level grayscale buffers. Identify modified pixel rows. 4. Commands: Send PARTIAL_UPDATE command to ED047TC1. Use window registers to limit refresh area to detected rows. 5. Verification: Measure refresh time. It should be <200ms for small areas vs 2s for full refresh. 6. Deep Dive: Handle ghosting artifacts by alternating a full refresh every 50 partial updates to recalibrate liquid crystals.
