• Type : I2C type

Software Support

We provide a library for the 16x12 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 16x12 Click driver.

Standard key functions :

• Config Object Initialization function.

  void c16x12_cfg_setup ( c16x12_cfg_t *cfg );

• Initialization function.

  C16X12_RETVAL c16x12_init ( c16x12_t ctx, c16x12_cfg_t cfg );

• Click Default Configuration function.

  void c16x12_default_cfg ( c16x12_t *ctx );

Example key functions :

• Functions for display Image

  void c16x12g_display_image ( c16x12_t ctx, uint16_t pImage );

• Functions for display one Byte

  void c16x12g_display_byte ( c16x12_t *ctx, char ch );

• Functions for display text with scroll

  void c16x12g_display_text ( c16x12_t ctx, char p_text, uint8_t n_char, uint8_t speed );

Examples Description

This application draw object with led diodes.

The demo application is composed of two sections :

Application Init

Initialization default device configuration, sets LED mode, configuration ABM and display one character.

    log_cfg_t log_cfg;
    c16x12_cfg_t cfg;

     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work.

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.16x12

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.
