Software Support

We provide a library for the Eink290Inch Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Eink290Inch Click driver.

Standard key functions :

Example key functions :

Examples Description

This application demonstrates the use of eINK click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and configures the click board for 2.90 inch eINK display. After that, if the TEXT mode is supported, shows a desired text messages on the display.

void application_init ( void )
{
// Click initialization.
EINK290INCH_MAP_MIKROBUS( cfg, MIKROBUS_1 );
eink290inch_init( &eink290inch, &cfg );
eink290inch_start_config( &eink290inch );
Delay_ms( 1000 );
#ifndef IMAGE_MODE_ONLY
eink290inch_set_font( &eink290inch, &cfg_font );
text_set.n_char = 4;
text_set.text_x = 5;
text_set.text_y = 50;
eink290inch_text( &eink290inch, &demo_text[ 0 ], &text_set );
Delay_ms( 1000 );
eink290inch_set_font( &eink290inch, &cfg_font );
text_set.n_char = 7;
text_set.text_x = 5;
text_set.text_y = 90;
eink290inch_text( &eink290inch, &demo_text1[ 0 ], &text_set );
Delay_ms( 1000 );
cfg_font.p_font = &guiFont_Tahoma_8_Regular[ 0 ];
eink290inch_set_font( &eink290inch, &cfg_font );
text_set.n_char = 9;
text_set.text_x = 5;
text_set.text_y = 120;
eink290inch_text( &eink290inch, &demo_text2[ 0 ], &text_set );
Delay_ms( 1000 );
#endif
}

Application Task

Draws four demo images to the display with a one-second delay between each drawing.

void application_task ( void )
{
Delay_1sec( );
eink290inch_display_image( &eink290inch, &demoImage_dark[ 0 ] );
Delay_1sec( );
Delay_1sec( );
Delay_1sec( );
}

Note

Due to insuficient RAM memory, only the IMAGE mode is supported with 8-bit PIC and AVR microcontrollers.

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Eink290Inch

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
