Communication Protocols

Explore the world of Communication Protocols in Embedded Systems and VLSI Design.

At PiEmbSysTech, we simplify complex data-exchange technologies that power modern electronics, IoT devices, and automotive ECUs. Learn how microcontrollers, SoCs, and semiconductor IPs communicate efficiently using industry-standard interfaces such as I²C, SPI, UART, CAN, LIN, FlexRay, UDS, OBD-II, Ethernet, USB, Bluetooth, Wi-Fi, and DSRC.

Dive deeper into VLSI-level buses like AMBA, AXI, AHB, APB, and Wishbone, which form the backbone of on-chip communication in SoC and FPGA architectures. Understand timing, synchronization, data framing, and error-detection mechanisms critical for high-reliability systems.

Whether you’re working on embedded firmware, automotive networking, or chip-level interconnects, this category helps you master every layer of protocol design — from physical and data link layers to application-level diagnostics (UDS, DoIP).
