# hongtai-panel: reconstructing a cooler LCD's USB serial protocol

> hongtai-panel implements Linux control of a LovingCool AIO cooler LCD using a USB CDC-ACM serial protocol reconstructed from the vendor's Electron application. Its documentation describes control-frame layout, checksums, JSON replies, and opcodes; the client displays system statistics, media, or screen mirroring.
