An embedded 3D‐mapping system that uses the MSP-EXP432E401Y microcontroller and VL53L1X time‑of‑flight sensor mounted on a stepper motor to perform 360° scans in a vertical plane, capture fixed‑interval slices along the orthogonal axis, and stream the resulting point‑cloud data to a PC for real‑time reconstruction and visualization.
- MCU bus clock: 14 MHz
- Sensor & scan: VL53L1X ToF on stepper motor scanning every 11.25 degrees on vertical‑plane (y‑z) distance mapping
- Displacement slices: manual X‑axis steps (30 cm) to build full 3D point cloud
- Start/stop control: three momentary push buttons (one to start motor/data collection, one to stop motor/output data, and one to reset motor/rescan)
Status indicators (assigned):
- Measurement status LED → PN0
- UART‑TX activity LED → PN1
- Additional/troubleshoot LED → PF4
Comm protocols:
- I²C between MCU ↔ ToF sensor
- UART from MCU → PC for serial point‑cloud output
