3.3.1 Level 1 Incremental Build

Objectives of this build level:

  • Use the HAL to initialize the peripherals of the MCU.
  • Verify the PWM and ADC driver modules.
  • Verify the ADC Offset validation.
  • Become familiar with the operation of CCS.

In this build level, the board is executed in open loop mode with a fixed duty cycle. The duty cycles are set to 50%. This build level verifies the sensing of feedback values from the power stage and also operation of the PWM gate driver. Additionally, calibration of input and output voltage sensing can be performed in this build level. During this process the motor must remain disconnected. The software block diagram of this build level is shown in Figure 3-7.
