Pico GFX Pack (C++)

This library offers convenient functions for interacting with Pico GFX Pack - The Pico GFX Pack adds a 128x64 LCD Matrix display to your headered Raspberry Pi Pico or PicoW, with RGBW backlight and 5 input buttons for all your display and control needs.

Example Program

The following example sets up Pico Display, displays some basic demo text and graphics and will illuminate the backlight green if the A button is pressed.

#include "gfx_pack.hpp"
#include "drivers/st7567/st7576.hpp"
#include "libraries/pico_graphics/pico_graphics.hpp"
#include "rgbled.hpp"
#include "button.hpp"

// Display driver
ST7567 st7567(128, 64, GfxPack::gfx_pack_pins);

// Graphics library - in 1 Bit mode you get 16 shades with dithering.
PicoGraphics_Pen1Bit graphics(st7567.width, st7567.height, nullptr);

// RGB backlight elements
RGBLED backlight_rgb(GfxPack::BL_R, GfxPack::BL_G, GfxPack::BL_B, Polarity::ACTIVE_HIGH);

// And each button
Button button_a(GfxPack::A);
Button button_b(GfxPack::B);
Button button_c(GfxPack::C);
Button button_d(GfxPack::D);
Button button_e(GfxPack::E);


// RGB LED
RGBLED led(GfxPack::LED_R, GfxPack::LED_G, GfxPack::LED_B);

int main() {

    // set the backlight to a value between 0 and 255
    // This controls the white elements of the RGBW backlight
    st7567.set_backlight(100);

    while(true) {
        // detect if the A button is pressed (could be A, B, C, D or E)
        if(button_a.raw(display.A)) {
            // make the LCD glow green
            // parameters are red, green, blue all between 0 and 255
            // these are also gamma corrected
            backlight_rgb.set_rgb(0, 255, 0);
        }

        // set the colour of the pen
        // parameters are red, green, blue all between 0 and 255
        graphics.set_pen(30, 40, 50);

        // fill the screen with the current pen colour
        graphics.clear();

        // draw a box to put some text in
        graphics.set_pen(10, 20, 30);
        Rect text_rect(10, 10, 150, 150);
        graphics.rectangle(text_rect);

        // write some text inside the box with 10 pixels of margin
        // automatically word wrapping
        text_rect.deflate(10);
        graphics.set_pen(110, 120, 130);
        graphics.text("This is a message", Point(text_rect.x, text_rect.y), text_rect.w);

        // now we've done our drawing let's update the screen
        st7567.update(&graphics);
    }
}

Function Reference

PicoGraphics

Pico GFX Pack uses our Pico Graphics library to draw graphics and text. For more information read the Pico Graphics function reference..

ST7567

Pico Display uses the ST7567 display driver to handle the LCD. For more information read the ST7567 README..
