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.

Click library
- Author : Stefan Filipovic
- Date : Jul 2021.
- Type : SPI type
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.
Standard key functions :
bargraph4_cfg_setup
Config Object Initialization function.
void bargraph4_cfg_setup(bargraph4_cfg_t *cfg)
BarGraph 4 configuration object setup function.
BarGraph 4 Click configuration object.
Definition: bargraph4.h:114
bargraph4_init
Initialization function.
err_t bargraph4_init(bargraph4_t *ctx, bargraph4_cfg_t *cfg)
BarGraph 4 initialization function.
BarGraph 4 Click context object.
Definition: bargraph4.h:98
Example key functions :
bargraph4_enable_output
This function enables all outputs.
void bargraph4_enable_output(bargraph4_t *ctx)
BarGraph 4 enable output function.
bargraph4_set_output
This function sets all outputs to desired value by using SPI serial interface.
err_t bargraph4_set_output(bargraph4_t *ctx, uint16_t ch_mask)
BarGraph 4 set output function.
bargraph4_set_channel_level
This function sets the level of a desired bar graph channel.
bargraph4_level_t
BarGraph 4 Click bar level.
Definition: bargraph4.h:160
bargraph4_sel_ch_t
BarGraph 4 Click select channel.
Definition: bargraph4.h:147
err_t bargraph4_set_channel_level(bargraph4_t *ctx, bargraph4_sel_ch_t channel, bargraph4_level_t level)
BarGraph 4 set channel level function.
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.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
Delay_ms( 100 );
log_info( &logger, " Application Init " );
if ( SPI_MASTER_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
#define BARGRAPH4_MAP_MIKROBUS(cfg, mikrobus)
MikroBUS pin mapping.
Definition: bargraph4.h:83
void application_init(void)
Definition: main.c:28
Application Task
Changes the level of all bar graph channels every second. The channels level will be logged on the USB UART.
{
{
log_printf( &logger, " All channels set to level %u\r\n\n", ( uint16_t ) cnt );
Delay_ms( 1000 );
}
}

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.
