“The idea of building an RS232 to Ethernet bridge seemed like a great way to begin learning about embedded system design. Having created a working sample, though it was left with my teammate after graduation, I decided to recreate the project with more features and higher reliability. The project was later renamed from ‘STEDS’ to ‘NI-1’ (Network Interface 1) and finally ‘Pack-it’. Pack-it is based on a Motorola MC9S12 MCU and a CS8900A Cirrus Ethernet controller.”
