Click library

  • Author : Stefan Filipovic
  • Date : Oct 2022.
  • Type : ADC/I2C type

Software Support

We provide a library for the POT 5 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 POT 5 Click driver.

Standard key functions :

  • pot5_cfg_setup Config Object Initialization function.

    void pot5_cfg_setup ( pot5_cfg_t *cfg );
  • pot5_init Initialization function.

    err_t pot5_init ( pot5_t *ctx, pot5_cfg_t *cfg );

Example key functions :

  • pot5_read_voltage This function reads raw ADC value and converts it to proportional voltage level.

    err_t pot5_read_voltage ( pot5_t *ctx, float *voltage );
  • pot5_convert_voltage_to_percents This function converts analog voltage to potentiometer position in percents.

    uint8_t pot5_convert_voltage_to_percents ( pot5_t *ctx, float voltage );
  • pot5_set_vref This function sets the voltage reference for POT 5 Click driver.

    err_t pot5_set_vref ( pot5_t *ctx, float vref );

Example Description

This example demonstrates the use of POT 5 Click board by reading and displaying the potentiometer position.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    pot5_cfg_t pot5_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.
    pot5_cfg_setup( &pot5_cfg );
    POT5_MAP_MIKROBUS( pot5_cfg, MIKROBUS_1 );
    err_t init_flag = pot5_init( &pot5, &pot5_cfg );
    if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

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

Application Task

Reads and displays on the USB UART the potentiometer position in forms of voltage and percents once per second.


void application_task ( void )
{
    float voltage = 0;
    if ( POT5_OK == pot5_read_voltage ( &pot5, &voltage ) ) 
    {
        log_printf( &logger, " AN Voltage : %.3f V\r\n", voltage );
        log_printf( &logger, " Potentiometer : %u %%\r\n\n", 
                    ( uint16_t ) pot5_convert_voltage_to_percents ( &pot5, voltage ) );
        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.POT5

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.
