Bargraph 2 click

BarGraph 2 click is a 10-segment bar graph display click, which uses a high-quality, multicolor bar graph LED display. The bar graph display is a very popular device for displaying various properties, whether it be an audio level, current/voltage level, position of the encoder, and generally any property that can be displayed in a form of a bar graph.

Click library

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

Software Support

We provide a library for the Bargraph2 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 Bargraph2 Click driver.

Standard key functions :

Example key functions :

  • This function turns on the green LED diode of the chosen segment.

    void bargraph2_led_green ( bargraph2_t *ctx, uint8_t index );

  • This function turns on green LED diodes from the starting index to the end index.

    void bargraph2_leds_green ( bargraph2_t *ctx, int start_index, int end_index );

  • This function turns off all the LED diodes.

    void bargraph2_lights_out ( bargraph2_t *ctx );

Examples Description

The example starts off with the initalisation and configuration of the logger and click modules and later on showcases different ways of lighting LED diodes on the click.

The demo application is composed of two sections :

Application Init

This function initializes and configures the logger and click modules.

{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
BARGRAPH2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
bargraph2_init( &bargraph2, &cfg );
}

Application Task

This function shows the user how to light single and multiple LED diodes.

{
uint8_t cnt;
// Single LED switch
for ( cnt = 1; cnt <= 10 ; cnt++ )
{
bargraph2_led_green( &bargraph2, cnt );
Delay_ms( 200 );
bargraph2_led_red( &bargraph2, 10 - ( cnt - 1 ) );
Delay_ms( 200 );
}
bargraph2_lights_out ( &bargraph2 );
// Multiple LED switch
bargraph2_leds_green ( &bargraph2, 1, 10 );
Delay_ms( 1000 );
bargraph2_leds_red ( &bargraph2, 1, 10 );
Delay_ms( 1000 );
bargraph2_leds_yellow ( &bargraph2, 1, 10 );
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.Bargraph2

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.
