Set_Cursor(0) //turns off blinking cursor * SPI Wiring Reference for: NHD-0216K3Z-NSW-BBW-V3 You can adapt and expand the code examples to suit your specific Arduino-based project requirements.Ĭode example displays "Hello Word!" on the LCD.
In some examples below, this function is empty and does nothing because we just need to run some functions once. The loop() function runs in a continuous loop for the entire duration that the Arduino board is powered on.It is used to initialize the settings, variables and any run any other necessary functions and configurations for the project. The setup() function is the main function and is executed once when the Arduino starts.The Set_Cursor() function enables or disables the blinking cursor on the LCD display, depending on the input parameter.The Clear_Display() function clears the LCD screen.The Set_Backlight() function sets the backlight of the LCD display.The Set_Contrast() function sets the contrast of the LCD display.The Set_Pins() function configures the SPI pins as output pins.It does this by iterating through the 8 bits of the input byte and sending each bit's value to the LCD display. The SPI_Out() function sends commands and data to the LCD display through SPI.You will find helpful comments in the code examples, but let's break down some of the functions below:
The following code examples demonstrate how to use serial communication between Arduino and a 16x2 character LCD using the SPI interface. Wiring Schematic Arduino LCD circuit schematic.
Wiring circuit Arduino LCD circuit wiring. Display Manufacturer, Global Supplierīefore starting, ensure that the Arduino is powered off while wiring up the display.
