IndicatorDisplay drives the 480x480 ST7701S through LovyanGFX's Bus_RGB and Panel_ST7701 on the stock core; the CrowPanel 5.0 drives its RGB panel through the same Bus_RGB. The panel's CS and RESET sit on the TCA9535, so LovyanGFX gets pin_cs/pin_rst = -1 and begin() drives them through IndicatorIo: reset pulse, CS low, lcd.init(), CS high. The bus lock is held from CS low to CS high because the panel's 3-wire init shares GPIO41/48 with the radio SPI, and no other task may move the radio's NSS meanwhile. The second init list is Meshtastic device-ui's Indicator list (GPL-3.0, credited in NOTICE): MADCTL 0x10 and SDIR 0x04 in BK0 flip both axes, and the closing 0xFF,0xFF terminator keeps the colours from coming up inverted. The pixel clock is INDICATOR_PCLK_HZ, 12 MHz by default. The RGB bus reads its frame buffer out of PSRAM continuously and this core has no bounce buffers, so PSRAM bandwidth under Wi-Fi and flash traffic sets the limit, not the panel; 12 MHz leaves margin for that, and the value is a build flag. The backlight is Light_PWM on GPIO45, LEDC channel 7; brightness 0 writes duty 0, so it goes dark. begin() returns false with the backlight off when lcd.init() or any expander write in the sequence fails, since the panel may then have missed its reset or init. UITask keeps driving the backlight through the global display even when begin() failed, so setBrightness() and turnOn() do nothing until the panel has come up; otherwise the first brightness or wake request would light a blank panel. UITask: a 480 px draw band in internal DMA RAM (with LVGL told its full size), because the RGB panel scans its frame buffer out of PSRAM all the time and an internal band makes the flush a single PSRAM write. The resolution is 480x480 with no UI rotation, and the board shares the Wio L2's brightness, screen-sleep and no-keyboard-rotate branches.
