The calculated duty cycles are written to the ePWM compare registers, adjusting the hardware drive signals for the next switching cycle. Development and Tuning Workflow
The motor’s phase currents and DC bus voltage are sampled by the on-chip ADCs.
Detailed user guides and lab manuals ensure developers understand the theory and implementation behind each control technique.
Start by importing the project into Code Composer Studio (CCS) . This project is designed as a single codebase that supports multiple control techniques (FOC, Trapezoidal) and feedback types (Sensored, Sensorless). c2000ware motor control sdk work
The ISR stops background tasks and reads the digital values via the HAL layer, converting raw ADC counts into engineering units (Amperes and Volts). Step B: Processing and Estimation (The Math Engine)
These functions are written in optimized C and inline assembly. For example, when you call MATH_Clarke_a(ia, ib) , the SDK uses the C2000’s built-in __builtin_cosf and TMU to compute the angle in fewer cycles than standard floating-point.
At the base of the SDK is the HAL. The HAL abstracts the complex register structures of the C2000 hardware into readable C-functions. It configures the essential peripherals required for motor control: The calculated duty cycles are written to the
Before a motor can be controlled, the controller needs to understand its characteristics (e.g., resistance, inductance). The SDK includes technology or similar parameter identification routines that automatically calculate motor parameters. 3. Library Integration and Algorithm Development

The Space Vector Generator (SVG) module calculates the exact duty cycles required for the three phases of the inverter.
The C2000Ware MotorControl SDK is a comprehensive software repository, acting as a complete infrastructure for three-phase motor control applications. It is built upon the foundational , which provides device-specific drivers, libraries, and peripheral examples.
