BIG 7-SEG R Click is what you need if you want to add a seven-segment LED display to your project.
We provide a library for the Big7Seg 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Big7Seg Click driver.
Config Object Initialization function.
void big7seg_cfg_setup ( big7seg_cfg_t *cfg );
Initialization function.
BIG7SEG_RETVAL big7seg_init ( big7seg_t ctx, big7seg_cfg_t cfg );
Turn OFF BIG 7-SEG display
void big7seg_display_off ( big7seg_t *ctx );
Function write number
void big7seg_write_data_number ( big7seg_t *ctx, uint8_t display_number );
Function write character
void big7seg_write_data_character ( big7seg_t *ctx, char display_char );
This application sets seven-segment leds on the display.
The demo application is composed of two sections :
Driver initializaion and turning on the display by setting PWM pin to logic 1 and prepare to communcation via SPI.
void application_init ( void )
{
log_cfg_t log_cfg;
big7seg_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
big7seg_cfg_setup( &cfg );
BIG7SEG_MAP_MIKROBUS( cfg, MIKROBUS_1 );
big7seg_init( &big7seg, &cfg );
big7seg_set7seg( &big7seg );
Delay_100ms( );
}
This example shows functionality of the BIG 7-SEG R Click, shows number or character on display.
void application_task ( )
{
uint8_t counter;
big7seg_reset7seg( &big7seg );
big7seg_display_on( &big7seg );
Delay_1sec( );
big7seg_write_data( &big7seg, 0x40 );
Delay_1sec( );
big7seg_write_data_character( &big7seg, 'B' );
Delay_1sec( );
big7seg_write_data_character( &big7seg, 'I' );
Delay_1sec( );
big7seg_write_data_character( &big7seg, 'G' );
Delay_1sec( );
big7seg_write_data( &big7seg, 0x08 );
Delay_1sec( );
big7seg_write_data_number( &big7seg, 7 );
Delay_1sec( );
big7seg_write_data( &big7seg, 0x40 );
Delay_1sec( );
big7seg_write_data_character( &big7seg, 'S' );
Delay_1sec( );
big7seg_write_data_character( &big7seg, 'E' );
Delay_1sec( );
big7seg_write_data_character( &big7seg, 'G' );
Delay_1sec( );
big7seg_write_data( &big7seg, 0x00 );
Delay_1sec( );
for ( counter = 65; counter < 91; counter ++ )
{
big7seg_write_data_character( &big7seg, counter );
Delay_1sec( );
}
big7seg_display_off( &big7seg );
Delay_1sec( );
}
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
