SPI / I2C / UART Protocols

Understands the fundamentals of SPI / I2C / UART Protocols. Applies basic practices in daily work. Follows recommendations from the team and documentation.

Connects sensors and actuators to MCU via I2C and UART. Understands basic protocol principles: I2C addressing, UART baud rate. Uses logic analyzer for debugging.

Independently implements SPI/I2C/UART drivers: DMA transfers, error handling, multi-slave bus management. Debugs communication issues using logic analyzer.

Develops drivers for SPI/I2C/UART devices in IoT projects. Configures DMA for high-speed SPI exchange. Diagnoses bus issues with Saleae/Wireshark.

Designs high-performance communications: multi-slave SPI with chip select mux, I2C bus recovery, UART with custom protocol and CRC.

Designs hardware abstraction layer for SPI/I2C/UART in IoT platform. Optimizes bus throughput and ensures thread-safe access from RTOS tasks. Implements sensor hot-plug.

Defines communication protocol standards for the platform. Establishes unified driver architecture for SPI/I2C/UART, conducts driver reviews.

Defines hardware interface standards for the IoT product line. Establishes reference designs and reusable driver libraries for the team.

Shapes communication bus strategy: defines unified driver architecture across products, establishes bus performance standards, creates reference implementations for new MCU platform bring-up.

Defines enterprise hardware interfaces strategy for IoT. Evaluates new protocols (I3C, SPI Quad) for next generation. Builds platform driver architecture.
