Adapter click

Adapter click™ is a breakout board which simplifies connection of add-on boards with IDC10 headers to mikroBUS™ socket. There are two ways of establishing connection: using male or female IDC10 connectors.

Click library

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

Software Support

We provide a library for the Adapter 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.

Library Description

This library contains API for Adapter Click driver.

Standard key functions :

• Config Object Initialization function.

  void adapter_cfg_setup ( adapter_cfg_t *cfg );

• Initialization function.

  ADAPTER_RETVAL adapter_init ( adapter_t ctx, adapter_cfg_t cfg );

Example key functions :

• 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 );

• 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 );

Examples 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.

The demo application is composed of two sections :

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 );
    }
}

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.

Other mikroE Libraries used in the example:

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

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.
