Jhd-2x16-i2c — Proteus

By integrating an with a standard 16x2 character display, this component eliminates the massive wire clutter associated with traditional 4-bit or 8-bit parallel connections. Instead of hogging up to 6 or 8 GPIO pins on your microcontroller, it requires just two: SDA (Serial Data) and SCL (Serial Clock) .

You combine a standard 16x2 Character LCD (such as the LM016L) with an PCF8574 I2C I/O Expander . The PCF8574 acts as the "backpack" circuit that translates I2C commands from your microcontroller into parallel data for the JHD display. How to pick the components: jhd-2x16-i2c proteus

Check that the Wire.h library is included and that your connections (SDA/SCL) are correct. By integrating an with a standard 16x2 character
