Nokia 5110 Display Driver for Arduino

PCD8544 is a library for the Arduino to interface with LCDs based on the Philips PCD8544 controller. These displays are commonly found on monochrome mobile phones, such as the Nokia 3310 or 5110.

The library has a small memory footprint and is optimized a lot for fast refresh rates.

A full description to set up your display can be found here.

Functionality

Constructor

Initialize with software SPI with explicit CS pin

PCD8544(int8_t rst, int8_t sce, int8_t dc, int8_t din, int8_t sclk)

Initialize with software SPI with CS tied to ground. Saves a pin but the other pins can't be shared with other hardware

PCD8544(int8_t rst, int8_t dc, int8_t din, int8_t sclk)

Initialize with hardware SPI with hardware controlled SCK (SCLK) and MOSI (DIN). SCE is controlled by IO pin

PCD8544(int8_t rst, int8_t sce, int8_t dc)

Methods

Initialize the module with default settings

init(uint8_t contrast = 60, uint8_t bias = 0x03, uint8_t tempCoeff = 0x02)

Set contrast within interval [0-127]

setContrast(uint8_t contrast)

Set bias within interval [0-7]

setBias(uint8_t bias)

Set temperature coefficent within interval [0-3]

setTempCoeff(uint8_t temp)

Turn module on or off

setPower(bool on)

Set display mode

• PCD8544_DISPLAY_BLANK: All pixels blank
• PCD8544_DISPLAY_NORMAL: Normal operation
• PCD8544_DISPLAY_ALL_ON: All pixels set
• PCD8544_DISPLAY_INVERTED: All pixels inverted

setDisplayMode(pcd8544_display_t mode)

Set a pixel

setPixel(uint8_t x, uint8_t y, uint8_t color = 1)

Get pixel at position

getPixel(uint8_t x, uint8_t y)

Draw outline of a rectangle

strokeRect(uint8_t x1, uint8_t y1, uint8_t width, uint8_t height, uint8_t color = 1)

Draw a filled rectangle

fillRect(uint8_t x1, uint8_t y1, uint8_t width, uint8_t height, uint8_t color = 1)

Draw outline of a circl

strokeCircle(uint8_t x0, uint8_t y0, uint8_t radius, uint8_t color = 1)

Draw a filled circle

fillCircle(uint8_t x0, uint8_t y0, uint8_t radius, uint8_t color = 1)

Draw a line from point (x1, y1) to (x2, y2)

strokeLine(int8_t x1, int8_t y1, int8_t x2, int8_t y2, uint8_t color = 1)

Set a font face

setFont(uint8_t *font)

Write characters or strings at position (x, y)

• FONT_MODE_DEFAULT: Default behavior of font
• FONT_MODE_TRANSPARENT: Unset pixels of a font are transparent
• FONT_MODE_INVERTED: The written text is inverted
• FONT_MODE_AUTO_LINEBREAK: make linebreak when necessary (not good for marquees)
• FONT_MODE_IGNORE_NEWLINE: Replaces a \n character with a space.

print(char c, int16_t x, int16_t y, pcd8544_fontmode_t mode = FONT_MODE_DEFAULT)

print(char *c, int16_t x, int16_t y, pcd8544_fontmode_t mode = FONT_MODE_DEFAULT)

print(String st, int16_t x, int16_t y, pcd8544_fontmode_t mode = FONT_MODE_DEFAULT)

Send drawn buffer to the device

update()

Send a bitmap to the device

updateImage(const uint8_t *image)

Clears the canvas

clearBuffer()

Clears the display pixels

clear()

Bitmap support

You can easily generate images using our LCD image generator and put them on the display:

Geometry support

You can easily draw geometries like lines, rectangles or circles:
