Hello friends! In this tutorial, we will design a circuit that connects a 16×2 character LCD to a PIC18F452 microcontroller in Proteus ISIS. We will select the components, wire the display, write a small program in mikroC PRO for PIC, load its HEX file into the simulated microcontroller, and display text on both rows. This is a useful first microcontroller simulation because it combines several skills in one manageable circuit: choosing the correct device, matching software pins to schematic wires, setting the clock frequency, and checking the result. If you are new to the workspace, start with our Proteus ISIS and ARES guide , then return here for the practical example. We will preserve the original PORTD connections and two-line website message. The explanation now also covers the LCD co ...
