PCNT measurement showed I2S0 BCK (VCLK) rising once per two bytes in 8-bit LCD mode, so the panel saw every other byte. Each VCLK is now two identical bytes at a 10 MHz byte rate (VCLK 5 MHz). The doubled ~142 KB stream is allocated as 38 per-descriptor chunks. The test sketch now cycles through 12 labelled test images. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Unit tests (PlatformIO Unit Testing / Unity) go here. Planned first test: EL512Panel::encodeRow() - check that HS is high for exactly 256 clocks per visible row, VS appears only on the last blanking line, that x = 0 (datasheet column 1, odd) lands on TVID and x = 1 on VID, and that each clock is two identical bytes with stream byte i stored at index i ^ 2 (8-bit I2S byte order). Run with: pio test -e esp32dev More info: https://docs.platformio.org/en/latest/advanced/unit-testing/index.html
