Examples

All the examples share in common the following code, which is not mentioned in the pages of the elements.

The section below includes the SDK and the libraries, and defines the variables.

Main code

// SDK and configuration
#include "PDLS_Common.h"

// Set parameters
#define DISPLAY_EXAMPLE 1

// Define variables and constants
// Board
Board_EXT myBoard = boardRaspberryPiPico_RP2040_EXT3;

// Driver
#include "Pervasive_Wide_Small.h"
Pervasive_Wide_Small myDriver(eScreen_EPD_271_KS_09, myBoard);

// Screen
#include "PDLS_Basic.h"
Screen_EPD myScreen(&myDriver);

// Fonts
uint8_t fontExtra, fontLarge, fontMedium, fontSmall;

// Orientation
const uint8_t myOrientation = ORIENTATION_LANDSCAPE;

The code below is specific to each example.

Main code

// Functions
#if (DISPLAY_EXAMPLE == 1)

void displayExample()
{
    myScreen.selectFont(fontMedium);

    myScreen.gText(4, 4, "Example");

    myScreen.flush();
}

#endif // DISPLAY_EXAMPLE

The main code initialises the screen, loads the fonts, then calls the example.

Main code

// Add setup code
void setup()
{
    hV_HAL_begin();

    hV_HAL_Serial_crlf();
    hV_HAL_log(LEVEL_INFO, __FILE__);
    hV_HAL_log(LEVEL_INFO, __DATE__ " " __TIME__);
    hV_HAL_Serial_crlf();

    // Initialise screen
    myScreen.begin();
    hV_HAL_Serial_crlf();

    // Fonts
    fontSmall = Font_Terminal6x8;
    fontMedium = Font_Terminal8x12;
    fontLarge = Font_Terminal12x16;
    fontVery = Font_Terminal16x24;

    // Example
#if (DISPLAY_EXAMPLE == 1)

    hV_HAL_log(LEVEL_INFO, "DISPLAY_EXAMPLE... ");
    myScreen.clear();
    displayExample();
    hV_HAL_delayMilliseconds(8000);

#endif // DISPLAY_EXAMPLE

    // Against possible ghosting
    myScreen.regenerate();

    hV_HAL_exit(RESULT_SUCCESS);
}

// Add loop code
void loop()
{
    hV_HAL_delayMilliseconds(1000);
}
