This project is an example implementation of a driver to control a 16x2 LCD display using the I2C interface on the NUCLEO-F411RE board with the STM32 microcontroller. NUCLEO-F411RE board with an STM32 ...

The schematic for this module is based on an excellent blog post about connecting an LCD to a Z80 with two glue chips by Mike Sutton (or more accurately, on my own attempt to do the same thing, ...

The PIC does the job of translating the original display, which had a fair number of custom icons and symbols, into sensible text-based equivalents and sending them to the 16×2 via I2C.
