5 LCD Layout and Software Considerations

Choosing the right LCD and carefully choosing which MSPM0 pins to connect to particular pins of the display makes a big difference in the ease of use of code and code efficiency. This efficiency ties into how the display MUXes different areas together onto the same segment pin, in relation to what is displayed on the segment (for example, alphabet characters or numbers). While deciding on a layout, take into consideration the way that the MSPM0 LCD memory is structured in different muxing modes to provide efficient and easy to use software.
