This paper describes a serial-to-Ethernet bridge using the MCF51CN128, the open-source RTOS FreeRTOS v5.3.0 and the TCP/IP stack LwIP v1.3.0. Serial interfaces used are UART and SPI. Ethernet connects using a well-known socket implementation. This paper was written to help you enable older serial interface-related designs for Ethernet connectivity. Microcontrollers usually connect through interfaces like SCI (or UART) and SPI. For this particular application, the microcontroller used is the MCF51CN128, which supports Ethernet-based connectivity. To take advantage of this paper, it is not mandatory to have in-depth Ethernet protocol knowledge.
