Guide: Using JHD2x16 I2C LCD with Proteus (Free)
Overview
This guide shows how to simulate a JHD2x16 (standard 16x2 character LCD) controlled via I2C in Proteus using free tools and libraries, including wiring, required components, code example (Arduino), and troubleshooting.
A Quick Start Guide for the Simulation
Once you have your component placed (either the library model or the PCF8574+LM016L combo), the code is universal. jhd2x16i2c proteus free
To simulate the JHD2X16I2C in Proteus, you need two distinct sets of libraries: Proteus Component Library Guide: Using JHD2x16 I2C LCD with Proteus (Free)
Error 1: "I2C slave not acknowledged at address 0x20"
- Cause: Proteus defaults to PCF8574 address 0x20, but your code uses 0x27.
- Fix: Double-click PCF8574 and check "Initial I2C Address". Change your code to match (or edit the component properties).
// Set the I2C address (usually 0x27 or 0x3F) // For PCF8574 default address in Proteus is often 0x20 or 0x27 LiquidCrystal_I2C lcd(0x27, 16, 2); Cause: Proteus defaults to PCF8574 address 0x20, but
Step 3: Restart Proteus and Verify
- Open Proteus.
- Click on Component Mode (P button).
- Search for jhd2x16i2c in the Keywords field.
- If found, you have successfully added it for free.
