Hardware Interfaces

Understands basic hardware interfaces: GPIO, UART, SPI, I2C. Reads device datasheets, connects simple peripherals under mentor guidance.

Independently works with hardware interfaces: PCIe, USB, Ethernet PHY. Reads schematics, uses logic analyzer for protocol debugging, implements timing requirements.

Designs low-level hardware interaction: implements custom protocols, optimizes DMA transfers via scatter-gather, works with MMIO and I/O port mapping.

Defines hardware interface standards for the platform. Establishes HAL strategy, conducts hardware-software interface reviews, coordinates with the HW team.

Shapes enterprise approach to hardware interfaces. Defines strategy for supporting new interfaces (CXL, UCIe), manages hardware-software co-design process.
