Click library

  • Author : Stefan Ilic
  • Date : Oct 2023.
  • Type : I2C type

Software Support

We provide a library for the Step Down 11 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 Step Down 11 Click driver.

Standard key functions :

  • stepdown11_cfg_setup Config Object Initialization function.

    void stepdown11_cfg_setup ( stepdown11_cfg_t *cfg );
  • stepdown11_init Initialization function.

    err_t stepdown11_init ( stepdown11_t *ctx, stepdown11_cfg_t *cfg );
  • stepdown11_default_cfg Click Default Configuration function.

    err_t stepdown11_default_cfg ( stepdown11_t *ctx );

Example key functions :

  • stepdown11_get_resistance Step Down 11 get the resistance function.

    err_t stepdown11_get_resistance ( stepdown11_t *ctx, uint8_t wiper_sel, float *res_kohm );
  • stepdown11_set_voltage Step Down 11 set voltage output function.

    err_t stepdown11_set_voltage ( stepdown11_t *ctx, float v_out );
  • stepdown11_set_mode Step Down 11 set S-CONF device configuration mode function.

    err_t stepdown11_set_mode ( stepdown11_t *ctx, float sconf_mode );

Example Description

This library contains API for the Step Down 11 Click driver. This driver provides the functions to set the output voltage treshold.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After driver initialization, default settings sets output voltage to 1 V.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    stepdown11_cfg_t stepdown11_cfg;  /**< Click config object. */

    /** 
     * 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.
    stepdown11_cfg_setup( &stepdown11_cfg );
    STEPDOWN11_MAP_MIKROBUS( stepdown11_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == stepdown11_init( &stepdown11, &stepdown11_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( STEPDOWN11_ERROR == stepdown11_default_cfg ( &stepdown11 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

This example demonstrates the use of the Step Down 11 Click board™ by changing output voltage every 5 seconds starting from 1 V up to 5 V.

void application_task ( void ) 
{
    for ( uint8_t vout = 1; vout <= 5; vout++ )
    {
        log_printf( &logger, " Set output voltage %dV \r\n", ( uint16_t ) vout );
        stepdown11_set_voltage ( &stepdown11, vout );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
    }
}

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.StepDown11

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.

MCP2518FD click

5

MCP2518FD Click is a compact add-on board representing a complete CAN solution used as a control node in a CAN network. This board features the MCP2518FD, an external CAN FD controller with an SPI interface, and a high-speed CAN transceiver, the ATA6563, both from Microchip. The ATA6563, a low-level physical layer IC (PHY), provides a physical connection with the CAN bus itself, while the CAN controller MCP2518FD represents an interface between the MCU and the PHY. It features three operating modes with dedicated fail-safe features, remote wake-up via CAN, and ideally passive behavior when powered off on the CAN bus. This Click boardâ„¢ is suitable for developing a wide range of automotive diagnostic applications, even on MCUs that do not natively support CAN interface.
