UT-S 7-SEG B 2 click

UT-S 7-SEG B 2 Click is a compact add-on board that presents an easy solution for adding a numeric or hexadecimal display to your application. This board features the TLC5947, a constant-current sink LED driver from Texas Instruments, alongside six ultra-thin blue single-digit numeric displays, the JSS-3011BUB-21. The displays are small in size (0.39 inches in height) and can display letters, numbers, and symbols in a highly readable form. The host MCU can control the light intensity of the blue segments of the display.

  • Date : Nov 2023.
  • Type : SPI type

Software Support

We provide a library for the UT-S 7-SEG B 2 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 UT-S 7-SEG B 2 Click driver.

Example Description

This example demonstrates the use of the UT-S 7-SEG B 2 Click board by writing and displaying the desired numbers on the screen.

The demo application is composed of two sections :

Application Init

Initialization of SPI module and log UART. After driver initialization, the app executes a default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
uts7segb2_cfg_t uts7segb2_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
uts7segb2_cfg_setup( &uts7segb2_cfg );
UTS7SEGB2_MAP_MIKROBUS( uts7segb2_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == uts7segb2_init( &uts7segb2, &uts7segb2_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( UTS7SEGB2_ERROR == uts7segb2_default_cfg ( &uts7segb2 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
number.brightness_top = UTS7SEGB2_BRIGHTNESS_DEFAULT;
number.brightness_bottom = UTS7SEGB2_BRIGHTNESS_DEFAULT;
log_info( &logger, " Application Task " );
Delay_ms( 100 );
}

Application Task

The demo application draws numbers, in hexadecimal format, from 0h to FFFh on the top segment group and from FFFh to 0h on the bottom segment group. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
for ( uint16_t num_cnt = 0; num_cnt <= UTS7SEGB2_HEXADECIMAL_NUM_MAX; num_cnt++ )
{
number.num_top = num_cnt;
number.num_bottom = UTS7SEGB2_HEXADECIMAL_NUM_MAX - num_cnt;
if ( UTS7SEGB2_OK == uts7segb2_display_number( &uts7segb2, number ) )
{
log_printf( &logger, " %.3X\r\n", number.num_top );
log_printf( &logger, " %.3X\r\n\n", number.num_bottom );
Delay_ms( 100 );
}
}
log_printf( &logger, " --------------\r\n\n" );
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.UTS7SEGB2

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. UART terminal is available in all MikroElektronika compilers.
