Detailed Description
class tinygpu::NV3041ADriver< RGB_T >
Driver for the New Vision NV3041A QSPI TFT controller (480x272 panels on Guition/Sunton JC4827W543-class ESP32-S3 boards).
The full vendor register-unlock/gate/source-timing/gamma init sequence, confirmed against real hardware (ported from moononournation/Arduino_GFX's Arduino_NV3041A driver - an earlier minimal sleep-out/pixel-format/MADCTL/display-on sequence produced a rotated color channel mapping: red rendered as blue, green as red, blue as green). Register 0x3A (pixel format) uses a chip-specific encoding on this part, not the standard MIPI-DCS one: 0x01 selects 16bpp RGB565 here, not the commonly-documented 0x55.
Platform-independent: works over any IQSPIBus, so the same class covers ESP32 (QSPIBusESP32, hardware/DMA), RP2040 and STM32 (QSPIBusBitBang, software) - see DisplayDriverQSPI's class comment. Only bring-up on ESP32 has been confirmed against real hardware; the RP2040/STM32 bit-bang path follows the same documented wire protocol but has not been run on real hardware.
