How Does SPI and Register-Level Control Work in W5500 Ethernet Communication? A Driver-Level Walkthrough of SPI Transactions, Register Access, and Buffer Handling (W5500의 SPI 및 레지스터 제어는 어떻게 동작하는가?) Summary (40–60 words) This article explains how the W5500 Ethernet controller is controlled at the driver level using SPI communication and register access. By analyzing SPI frame structure, register read/write operations, and buffer management, developers can understand how low-level firmware interacts with W5500 to enable reliable Ethernet communication in embedded systems. 1. Why Driver-Level…
