Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the BarGraph3 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 BarGraph3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void bargraph3_cfg_setup ( bargraph3_cfg_t *cfg );

  • Initialization function.

    BARGRAPH3_RETVAL bargraph3_init ( bargraph3_t ctx, bargraph3_cfg_t cfg );

Example key functions :

  • This function control the displey.

    void bargraph3_display ( bargraph3_t *ctx, uint8_t ctrl, uint8_t dir, uint8_t counter);

  • This function set PWM.

    void bargraph3_set_pwm ( bargraph3_t *ctx, uint8_t state );

  • Functions for enable the chip.

    void bargraph3_enable ( bargraph3_t *ctx, uint8_t state );

Examples Description

Used to create various types of VU meters, status indicators, different types of counters and similar devices.

The demo application is composed of two sections :

Application Init

Initialization driver init, enable device and set PWM.


void application_init ( void )
{
 log_cfg_t log_cfg;
    bargraph3_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    bargraph3_cfg_setup( &cfg );
    BARGRAPH3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    bargraph3_init( &bargraph3, &cfg );
}

Application Task

Counter passes through the loop and logs the value of the counter on the bargraph display.


void application_task ( void )
{
    uint8_t bargraph_cnt;

    for (bargraph_cnt = 0; bargraph_cnt <= 5; bargraph_cnt++)
    {
        bargraph3_display(  &bargraph3, BARGRAPH3_INCREASE_LED,  BARGRAPH3_DIRECTION_BOTTOM_TO_TOP, bargraph_cnt);
        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.BarGraph3

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.

8x8 R Click is a 64 LED matrix display Click board™, composed of SMD LEDs organized in 8 rows by 8 columns. It has a digital brightness control in 16 steps, it can control every LED in the display matrix independently, it blanks the display on power up to eliminate glitches and it requires a single resistor to control the current through all the LEDs at once, which simplifies the design. 8x8 R Click uses a fast SPI communication protocol, allowing fast display response and no lag.8x8 R Click is an add-on board in mikroBUS form factor.
