Some legacy products may only contain a serial port and accessing such products is increasingly becoming a challenge due to the inability to add multiple such products to a shared network and the inability to access the legacy product from long distances. A serial-to-Ethernet converter provides a simple solution to solve the above challenges. The software described in this application report allows an Ethernet-based TM4C129x microcontroller to be used as a serial-to-Ethernet converter. TM4C129x microcontroller is ideally suited for this application due to the integration of MAC and PHY on the microcontroller along with on-chip voltage regulator. This allows quicker time-to-market and cost savings. The software uses FreeRTOS to schedule the various tasks and runs out of the box on an EK-TM4C1294XL board.
