UT-L 7-SEG B click

UT-L 7-SEG B 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 two blue JSS-5611BUB-21s, ultra-thin single-digit numeric displays from Ningbo Junsheng Electronics. The displays are medium (0.56 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 red segments of the display.

Software Support

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

Example Description

This example demonstrates the use of the UT-L 7-SEG B Click boardâ„¢ 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;
utl7segb_cfg_t utl7segb_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
utl7segb_cfg_setup( &utl7segb_cfg );
UTL7SEGB_MAP_MIKROBUS( utl7segb_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == utl7segb_init( &utl7segb, &utl7segb_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( UTL7SEGB_ERROR == utl7segb_default_cfg ( &utl7segb ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

The demo application draws numbers, in hexadecimal format, from 0h to FFh on the display.

void application_task ( void )
{
for ( uint8_t hex_num = 0x00; hex_num < 0xFF; hex_num++ )
{
if ( UTL7SEGB_OK == utl7segb_display_number( &utl7segb,
hex_num,
{
log_printf( &logger, " --- %.2X ---\r\n", ( uint16_t ) hex_num );
Delay_ms( 500 );
}
}
}

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.UTL7SEGB

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.
