Click library

  • Author : Katarina Perendic
  • Date : nov 2019.
  • Type : I2C type

Software Support

We provide a library for the 16x9 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 16x9 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void c16x9_cfg_setup ( c16x9_cfg_t *cfg );

  • Initialization function.

    C16X9_RETVAL c16x9_init ( c16x9_t *ctx, c16x9_cfg_t *cfg );

Example key functions :

Examples Description

Demo application is used to shows basic controls 16x9 click.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Set basic images and characters to be drawn on the screen.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
c16x9_cfg_setup( &cfg );
C16X9_MAP_MIKROBUS( cfg, MIKROBUS_1 );
c16x9_init( &c16x9, &cfg );
// Image ON
image_on.buf[ 0 ] = 0x0000;
image_on.buf[ 1 ] = 0xC630;
image_on.buf[ 2 ] = 0x6318;
image_on.buf[ 3 ] = 0x318C;
image_on.buf[ 4 ] = 0x18C6;
image_on.buf[ 5 ] = 0x318C;
image_on.buf[ 6 ] = 0x6318;
image_on.buf[ 7 ] = 0xC630;
image_on.buf[ 8 ] = 0x0000;
image_on.pwm = 250;
// Image OFF
image_off.buf[ 0 ] = 0xFFFF;
image_off.buf[ 1 ] = 0x39CF;
image_off.buf[ 2 ] = 0x9CE7;
image_off.buf[ 3 ] = 0xCE73;
image_off.buf[ 4 ] = 0xE739;
image_off.buf[ 5 ] = 0xCE73;
image_off.buf[ 6 ] = 0x9CE7;
image_off.buf[ 7 ] = 0x39CF;
image_off.buf[ 8 ] = 0xFFFF;
image_off.pwm = 250;
// Char
data_char.pwm = 250;
// Rectangle
rectangle.x = 1;
rectangle.y = 4;
rectangle.pwm = 250;
}

Application Task

Display character, image and rectangle every 1 second.

void application_task ( void )
{
// Task implementation.
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}

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.16x9

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.
