BarGraph 4 click

BarGraph 4 Click is a compact add-on board that contains four green four-segment LED bar graph displays. This board features the TLC59283, a 16-channel, constant-current sink light-emitting diode (LED) driver from Texas Instruments.

Software Support

We provide a library for the BarGraph4 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for BarGraph4 Click driver.

Example Description

This example demonstrates the use of BarGraph 4 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables output.

void application_init ( void )
{
log_cfg_t log_cfg;
bargraph4_cfg_t bargraph4_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
Delay_ms( 100 );
log_info( &logger, " Application Init " );
// Click initialization.
bargraph4_cfg_setup( &bargraph4_cfg );
BARGRAPH4_MAP_MIKROBUS( bargraph4_cfg, MIKROBUS_1 );
err_t init_flag = bargraph4_init( &bargraph4, &bargraph4_cfg );
if ( SPI_MASTER_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
bargraph4_enable_output( &bargraph4 );
log_info( &logger, " Application Task " );
}

Application Task

Changes the level of all bar graph channels every second. The channels level will be logged on the USB UART.

void application_task ( void )
{
{
log_printf( &logger, " All channels set to level %u\r\n\n", ( uint16_t ) cnt );
Delay_ms( 1000 );
}
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.BarGraph4

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.
