Adapter Click

Adapter 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 : MikroE Team
• Date : maj 2020.
• Type : I2C/SPI type

Software Support

Example Description

Adapter Click is a breakout board which simplifies connection of add-on boards. There are two ways of establishing connection: using male or female IDC10 connectors. Male header must be soldered on the top side of Adapter Click to connect the add-on board directly or via flat cable. Female header can be soldered either on the top, or the bottom side, depending on which one is more convenient in given circumstances.
There are two jumpers for SPI/I2C selection and one for selection of power supply range.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Adapter

Example Key Functions

• adapter_cfg_setup Config Object Initialization function.

void adapter_cfg_setup ( adapter_cfg_t *cfg );

• adapter_init Initialization function.

err_t adapter_init ( adapter_t *ctx, adapter_cfg_t *cfg );

• adapter_generic_write This function writes data to the desired register.

void adapter_generic_write ( adapter_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

• adapter_generic_read This function reads data from the desired register.

void adapter_generic_read ( adapter_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

Application Init

Initalizes I2C or SPI driver and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    adapter_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.

    adapter_cfg_setup( &cfg );
    ADAPTER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    adapter_init( &adapter, &cfg );
}

Application Task

This is an example that shows the use of the Adapter Click board (SPI mode - set as default). In I2C mode we are reading internal temperature from another device (THERMO 5 Click board). In SPI mode example we are writing "mikroElektronika" on SRAM Click board, and than reading from the same memory location.

void application_task ( void )
{
    float temp_value;

    if ( adapter.master_sel == ADAPTER_MASTER_SPI )
    {
        log_printf( &logger, " Writing text :\r\n" );
   
        for ( n_cnt = 0; n_cnt < 16; n_cnt++ )
        {
            sram_write_byte( &adapter, n_cnt, send_buffer[ n_cnt ] );
            Delay_ms ( 100 );
            log_printf( &logger, "%c", send_buffer[ n_cnt ] );
        }
    
    
        log_printf( &logger, "\r\n" );
        log_printf( &logger, " Read text :\r\n" );
        for ( n_cnt = 0; n_cnt < 16; n_cnt++ )
        {
            mem_data[ n_cnt ] = sram_read_byte( &adapter, n_cnt );
            Delay_ms ( 100 );
            log_printf( &logger, "%c", mem_data[ n_cnt ] );
        }   
        log_printf( &logger, "\r\n" );
        log_printf( &logger, "--------------------------\r\n" );
    
        Delay_ms ( 1000 );
    }
    else if ( adapter.master_sel == ADAPTER_MASTER_I2C )
    {
        temp_value = thermo5_read_inter_temp( &adapter );

        log_printf( &logger, " Thermo 5 internal temperature :  %.2f\r\n", temp_value );
        log_printf( &logger, "--------------------------\r\n" );
    
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
    }
}

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.
