Debugging Methodology — question 8 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
The signal path is: MCU GPIO -> gate driver IC -> power FET -> motor terminals. You have an oscilloscope.
A microcontroller commands a motor driver with a PWM signal at a set duty cycle, but the motor's actual speed doesn't match what the commanded duty cycle should produce. You confirm the MCU is generating the correct duty cycle on its GPIO pin. Walk me through how you'd trace the signal chain from there to find where it stops matching the command.
