Proteus includes a universal I2C-enabled 16x2 alphanumeric LCD that functions identically to the JHD2X16I2C. Open your Proteus workspace. Click on the (P) button. In the keywords search bar, type: PCF8574 and LM016L .
C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY Search for Component : Once installed, search for keywords like LCDLibraryTEP , or the specific JHD-2X16-I2C model in the component picker. Coding for JHD-2X16-I2C While standard 1602 LCDs often use the LiquidCrystal_I2C library, the JHD-2X16-I2C can sometimes be problematic with default configurations. Recommended Library : Some experts recommend the DF Robot LCD
