Pico Display Pack

Our Pico Display Pack offers a vibrant 1.14" (240x135) IPS LCD screen for your Raspberry Pi Pico it also includes four switches and and an RGB LED!

Working with it is very straightforward, we've included helper functions to handle every aspect of drawing to the screen and interfacing with the other hardware.

A very basic example program can be as simple as:

    #include "pico_display.hpp"

    using namespace pimoroni;

    uint16_t buffer[PicoDisplay::WIDTH * PicoDisplay::HEIGHT];
    PicoDisplay pico_display(buffer);

    int main() {
        pico_display.init();

        // set the backlight to a value between 0 and 255
        // the backlight is driven via PWM and is gamma corrected by our
        // library to give a gorgeous linear brightness range.
        pico_display.set_backlight(100);

        while(true) {
            // detect if the A button is pressed (could be A, B, X, or Y)
            if(pico_display.is_pressed(pico_display.A)) {
                // make the led glow green
                // parameters are red, green, blue all between 0 and 255
                // these are also gamma corrected
                pico_display.set_led(0, 255, 0);
            }

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

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

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

            // write some text inside the box with 10 pixels of margin
            // automatically word wrapping
            text_rect.deflate(10);
            pico_display.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
        pico_display.update();
    }
