JDI JD9165 MIPI-DSI display panel, driven over ESP-IDF's esp_lcd_jd9165 component (DPI/DBI
|
|
interface, ESP32-P4 and other SOC_MIPI_DSI_SUPPORTED targets only). Owns the MIPI DSI PHY LDO
|
|
channel and DSI bus directly, so unlike SPI/RGB panels it has no parent bus controller device.

description: By default, when draw_bitmap's color_data is one of the panel's own frame
|
|
buffers (i.e. LVGL is bound directly onto them), draw_bitmap waits for a full scan-out to
|
|
complete before returning so the caller can't start overwriting a buffer still being
|
|
displayed. Set this to trade away that tear-free guarantee for lower latency (e.g. when
|
|
other tasks occasionally block timing for long enough that waiting causes visible stalls).
