For a cleaner schematic, you can install a dedicated I2C LCD library:
Now that you understand the power of the jhd2x16i2c proteus exclusive toolchain, here are three projects you can simulate today:
In the simulation, double-check that the backlight terminal is connected to positive voltage. Conclusion jhd2x16i2c proteus exclusive
Two 4.7kΩ resistors (Required for the I2C bus lines) Power Source: VCC (+5V) and Ground terminals Wiring Topology (Arduino Uno Example)
Uses only two pins ( SDA - Serial Data, SCL - Serial Clock) for communication, saving valuable microcontroller I/O pins. For a cleaner schematic, you can install a
Here is a standard working code snippet for Arduino (ATmega328) that proves the simulation works. This uses the popular LiquidCrystal_I2C library.
需要特别指出的是，在网上流传的许多Proteus I2C LCD相关教程中，经常出现两种不同的表述： This uses the popular LiquidCrystal_I2C library
delay(2000); for(int pos = 0; pos < 16; pos++) lcd.scrollDisplayRight(); delay(300);
: Typically 0x27 or 0x3F , depending on the hardware jumper configuration. Setting Up the Proteus Environment
