UT-L 7-SEG B Click

UT-L 7-SEG B Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.


Click Library

  • Author : Nenad Filipovic
  • Date : Jul 2023.
  • Type : SPI type

Software Support

Example Description

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

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.UTL7SEGB

Example Key Functions

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 );
}
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
