atom_aiot: AIoT Hardware Research Notes (alfredzhang98/atom_aiot)

This post collects my notes and experiments on AIoT (Artificial Intelligence of Things) hardware. Code, hardware files, and bring‑up logs are maintained in the open-source repository atom_aiot for reuse and future expansion.

• Repository:
  • GitHub: https://github.com/alfredzhang98/atom_aiot

What this repo is for

Hands-on “edge intelligence + hardware,” including:

• Power‑up (“bring‑up”) of common development boards and peripheral drivers (UART, I2C/SPI, timers, PWM, DMA, ADC, etc.)
• Sensor/actuator integration and debugging (IMU, barometer, motors/servos, displays, radios, etc.)
• Reusable firmware scaffolding and drivers (primarily C/C++)
• Measurements and tuning logs (power, timing, link robustness, debouncing and filtering)

Repository structure (growing)

• iot_developboards/: PCB development boards hardware folder
  • Schematics, layouts (e.g., Altium), BOM, test points, power domains
  • Board bring‑up notes, self‑test checklist, minimal working examples
• iot_items/: Interface code folder
  • Peripheral interface/driver code (GPIO, UART, I2C, SPI, PWM, ADC, DMA)
  • Device modules (IMU, pressure/force, displays, motors/servos, radios)
  • Small reference demos with comments
