1.2 Software Flowchart

The Servo Drive with QEP software consists of:

  • Startup routine: configures the device, calculates analog-to-digital converter (ADC) offsets
  • Motor control interrupt service routine (ISR): started by the ADC end of conversion (EOC) or by the SDFM module.
  • Background loop: periodically updates the motor control parameters.

Tools required to run the application:

  • Code Composer Studio™
  • F29x Motor Control SDK

Refer to: Section 2.3

  • Required tool versions
  • Instillation instructions
  • Application software configuration
  • Running the example.
