CP2112 I²C Control Tool
A Python GUI application for communicating with I²C devices using the Silicon Labs CP2112 HID-to-I²C bridge. Supports register read/write operations and execution of command scripts. ✨ Features
✅ Read/write to 16-bit I²C registers (1 to 32 bytes)
✅ Execute custom scripts with WBlock syntax
✅ Batch processing via Sequence all mode
✅ GUI-based input for slave address (HEX/BIN), register and data
✅ Multi-byte read and write support
✅ Real-time CP2112 communication via HID
✅ Optional debug logging (--debug)
📜 Script Format Example
Addr=2D
WBlock(01, MyInit) = [ (0103, 01, 1), # Reset (0104, 0123, 2), # Set mode ]
Addr — target I²C slave address (hex)
WBlock(ID, Name) — script block with name and ID
Each tuple: (Register, Data, Length)
Use Sequence all to execute all blocks in order
