MHS35b (ILI9486) variant driver - fixed init sequence matching DTS exactly
# ILI9486.py — MHS35b/MHS35 variant (Pi 5 compatible, lgpio)
#
# Original: SirLefti/Python_ILI9486 (Waveshare)
# Modified: craigerl/hemna — MHS35b/MHS35 support + Pi 5
#
# Key differences from original:
# - Uses lgpio (Pi 5 compatible) instead of RPi.GPIO
# - regwidth=16: commands AND register data sent as [0x00, byte] pairs
# - Pixel data (bulk framebuffer writes) sent as raw bytes
# - Pixel format: RGB565 (0x55) instead of RGB666 (0x66)

Analysis: MHS35b (ILI9486) variant support for Python_ILI9486 driver — Issue #6
# ILI9486_MHS35b.py — MHS35b variant support for Python_ILI9486
#
# Drop-in subclass of ILI9486 that provides:
# 1. MHS35b-specific init sequence (manufacturer registers, power/VCOM tuning)
# 2. RGB565 pixel format (16-bit) instead of RGB666 (18-bit)
#
# Usage:
# from ILI9486_MHS35b import ILI9486_MHS35b, image_to_data_565
# spi = SpiDev()
# spi.open(0, 0)
