Extend the ASUS Ryuo I 240 driver with: - get_status(): read coolant temperature from sensor register 0x6A - set_color(): LED control with 6 modes (off, static, breathing, flash, spectrum, rainbow) via commands 0x3B/0x3F - set_screen(): OLED display upload using the 9-step chunked transfer protocol reverse-engineered from LiveDash v1.05.03 (AuraIC.dll) The OLED upload sends GIF data in 62-byte HID chunks with 20ms delays (hardware SPI flash speed limit). Images are auto-resized to 160x128 using Pillow (optional dependency, imported at call time). WARNING: Register 0x5C must never be written after upload — it causes the OLED to go permanently black until a full power cycle. Tested on hardware. All 16 tests pass, 531 full suite pass.

There is a hid for direct frame buffer write. No point using their garbage implementation of writing to spi also I don’t expect this to be merged. both this and openrgb maintainers seem very upset about inorganic code… the matter that you can point a binaryninja/ida/ghidra harness at the binaries and it reverses it in an hour, seems to hurt their ego |
