Curtis Integrated Toolkit
Enterprise Windows software suite for CAN-based motor controller systems at Curtis Instruments
CIT is a fully integrated development and diagnostic platform used by OEM engineers worldwide to design, configure, and debug vehicle control systems running on Curtis CAN-based hardware. It provides a whole-system view of every device on the CANbus, enabling live monitoring, parameter tuning, and software updates from a single environment.
I maintained and enhanced core applications within the suite, including Programmer, TACT (a virtual oscilloscope for real-time parameter tracing across multiple CAN devices), Menu Editor, VCL Studio (a custom code editor and compiler), and Pack & Flash. All of these share a common project environment and live CANbus communication layer. The platform supports configurable access levels from factory engineering down to field service.
- .NET Framework 4.7.2, Windows Forms, OOP principles and design patterns
- LightningChart controls for high-performance real-time data visualization
- CANopen protocol for reading device configurations and flashing embedded applications to motor controller hardware
- Backend API integration for licensing, version management, automated updates, and firmware rollback
- InstallShield for packaging and distribution

I built and maintained the portal, handling both the frontend and backend, including the licensing and e-commerce workflow, document management system, and user access controls across different customer tiers.
