Detailed Description
class tinygpu::ST7701Driver< RGB_T >
Driver for the Sitronix ST7701S MIPI-DSI TFT controller, as wired on the Guition JC4880P443C_I_W (ESP32-P4, 480x800 portrait, 4.3").
Init register sequence, DSI lane config (2 lanes @ 500Mbps), DPI clock (34MHz) and video timing all transcribed verbatim from guition-jc4880p4-bsp's board_p4_st7701_init.h / board_p4.c (https://github.com/ultramcu/guition-jc4880p4-bsp), which documents them as VERIFIED-ON-HARDWARE on this exact board - this class only re-expresses that same recipe as a TinyGPU DisplayDriver instead of a bespoke BSP function, it does not add or change any of the underlying values. As with every other example in this repo's esp32-p4-480x800-guition-mipi-dsi-touch-display board directory, this file itself has not been run on real hardware.
Register meanings beyond 0x11 (SLPOUT) / 0x29 (DISPON) are vendor-specific (ST7701 command-bank-switched extension registers) and undocumented beyond that source.
