Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : SPI type

Software Support

We provide a library for the Adc2 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 Adc2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void adc2_cfg_setup ( adc2_cfg_t *cfg );

  • Initialization function.

    ADC2_RETVAL adc2_init ( adc2_t ctx, adc2_cfg_t cfg );

  • Click Default Configuration function.

    void adc2_default_cfg ( adc2_t *ctx );

Example key functions :

  • Function is used to check overflow high state.

    uint8_t adc2_check_over_high ( adc2_t *ctx );

  • Function is used to check overflow low state.

    uint8_t adc2_check_over_low ( adc2_t *ctx );

  • Function is used to read specific data from ADC convertor.

    uint32_t adc2_adc_value_read ( adc2_t *ctx );

Examples Description

This application enables usage of the 22bit ADC.

The demo application is composed of two sections :

Application Init

Initalizes SPI driver and makes an initial log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    adc2_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.

    adc2_cfg_setup( &cfg );
    ADC2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    adc2_init( &adc2, &cfg );

    Delay_ms ( 100 );

    log_printf( &logger, "------------------\r\n" );
    log_printf( &logger, "    ADC 2 Click   \r\n" );
    log_printf( &logger, "------------------\r\n" );
}

Application Task

This is an example that shows the capabilities of the ADC 2 Click


void application_task ( void )
{
    uint32_t adc_val;

    //  Task implementation.

    adc_val = adc2_adc_value_read( &adc2 );

    log_printf( &logger, "Value : %d", adc_val );
    log_printf( &logger, "------------------\r\n" );
    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.Adc2

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.

USB-C Power Click

0

USB-C Power Click is a compact add-on board that provides a quick and easy way to supply power without carrying multiple adapters or cables. This board features the TPS25750S, a highly integrated USB Type-C and Power Delivery (PD) controller with integrated power switches optimized for power applications from Texas Instruments. The TPS25750S integrates fully managed power paths (5V/3A with 36mΩ sourcing switch) with robust protection (reverse and inrush current as well as over/under voltage protection) and control for external battery charger IC for a complete USB-C PD solution. Besides web-based GUI and pre-configured firmware, the TPS25750S also has some GPIOs and LED indicators that are user-defined for either status or control information.
