Jhd-2x16-i2c Proteus | 2K |
When searching the native Proteus Pick Devices catalog, searching for "JHD-2X16-I2C" directly can sometimes yield no results depending on your specific library version or third-party additions.
: PCF8574 chips use 0x27 , while PCF8574A chips use 0x3F . Change the address in LiquidCrystal_I2C lcd(0x27, 16, 2); to match your Proteus component properties. I2C Bus Collision Errors

This is invaluable for learning the I2C protocol. When searching the native Proteus Pick Devices catalog,
: If the screen remains blank in Proteus, double-check that the pull-up resistors (typically
: Connect to Analog Pin A4 on the Arduino Uno. Here's an example code in C using the
To successfully simulate the JHD-2x16-I2C in Proteus, the following connections are required between the PCF8574 and the LCD (LM016L).
Here's an example code in C using the Arduino library:
void setup() // Initialize the LCD lcd.init();
The most critical aspect of simulation is the I2C address.
