This document presents a method of implementing a segment LCD controller via a software method. This method can be utilized to bring segment LCD capabilities to devices that do not have hardware modules available for controlling segment LCDs. This document explains the software method used in detail; however, details on how segment LCDs operate and the different implementation available are outside the scope of this document.

The software associated with this document can be found under the "Demos" folder for a given MSPM0 MCU in the MSPM0 SDK.
