Click library

  • Author : Stefan Filipovic
  • Date : Sep 2021.
  • Type : SPI type

Software Support

We provide a library for the Waveform4 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 Waveform4 Click driver.

Standard key functions :

  • waveform4_cfg_setup Config Object Initialization function.

    void waveform4_cfg_setup ( waveform4_cfg_t *cfg );
  • waveform4_init Initialization function.

    err_t waveform4_init ( waveform4_t *ctx, waveform4_cfg_t *cfg );
  • waveform4_default_cfg Click Default Configuration function.

    err_t waveform4_default_cfg ( waveform4_t *ctx );

Example key functions :

  • waveform4_set_frequency This function sets the sine and cosine (DDS) waves output frequency.

    err_t waveform4_set_frequency ( waveform4_t *ctx, uint32_t freq );
  • waveform4_set_gain This function sets the gain level of a desired channel.

    err_t waveform4_set_gain ( waveform4_t *ctx, uint8_t channel, float gain );
  • waveform4_set_wave_output This function sets a desired output signal wave to the selected channel.

    err_t waveform4_set_wave_output ( waveform4_t *ctx, uint8_t channel, uint8_t wave );

Example Description

This example demonstrates the use of Waveform 4 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration which resets the registers and sets the sine wave output with default gain and default frequency for all channels. After that it displays the list of supported commands on the USB UART.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    waveform4_cfg_t waveform4_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.
    waveform4_cfg_setup( &waveform4_cfg );
    WAVEFORM4_MAP_MIKROBUS( waveform4_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == waveform4_init( &waveform4, &waveform4_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( WAVEFORM4_ERROR == waveform4_default_cfg ( &waveform4 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    waveform4_display_commands ( );
    log_info( &logger, " Application Task " );
}

Application Task

Depending on the command character received from USB UART it changes the signal frequency, gain or wave of the selected channel.


void application_task ( void )
{
    uint8_t command = 0;
    if ( log_read ( &logger, &command, 1 ) > 0 ) 
    {
        waveform4_parse_command ( command );
    }
}

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.Waveform4

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.
