Here’s a structured content outline for “C2000WARE Motor Control SDK Work” — tailored for a blog post, LinkedIn article, technical report, or internal documentation.
Unlike generic ARM MCU code, the C2000 SDK is built for live tuning. Use Expression Window and Real-Time Emulation: c2000ware motor control sdk work
motorVars.speed_HzmotorVars.speedRef_Hz in real-timemotorVars.angle_rad versus FAST_est.angle_radHow does it work? The SDK implements a software frequency response analyzer (SFRA) module. You can inject a sine wave into the speed reference and graph the Bode plot live – without external equipment. Here’s a structured content outline for “C2000WARE Motor
The SDK uses a board-specific HAL. For example, if you use the BOOSTXL-DRV8320RS or TMDSIDDK447D evaluation kit, the SDK provides pre-written hal.c and hal.h files. These files initialize: Step 4: Real-Time Debugging – The "Work" Verifier
How it works: The HAL abstracts the pin mappings. Instead of manually calculating ADC trigger delays, you simply call HAL_setupPWM() and HAL_setupADCs(). This layer works by reading the target’s device tree (via board files) and configuring registers.
For motors spinning above 100,000 rpm, the default FAST observer gains may become unstable. Use the SDK’s FAST_setGains function.
How it works: The observer gain is a function of electrical speed (est_speed_Hz). The SDK’s FAST_setGains recomputes the observer poles at runtime. This is done in motor_common.c’s speed ramp handler.
Cause: The SDK project points to an environment variable (C2000WARE_ROOT) that is not set.
Fix: Set the environment variable in CCS or edit the project properties to absolute paths. Modern versions of the SDK use .projectspec files that automatically search relative paths, but legacy projects require this variable.
