Waveform Click

Waveform Click is a precise sine/triangle/square waveform generator, capable of reproducing frequencies up to 12MHz.

Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Waveform 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 Waveform Click driver.

Standard key functions :

  • waveform_cfg_setup Config Object Initialization function.

    void waveform_cfg_setup ( waveform_cfg_t *cfg ); 
  • waveform_init Initialization function.

    err_t waveform_init ( waveform_t *ctx, waveform_cfg_t *cfg );

Example key functions :

  • waveform_sine_output Sinusoide output function

    void waveform_sine_output ( waveform_t *ctx, uint32_t freq );
  • waveform_triangle_output Triangle output function

    void waveform_triangle_output ( waveform_t *ctx, uint32_t freq );
  • waveform_square_output Square output function

    void waveform_square_output ( waveform_t *ctx, uint32_t freq );

Examples Description

This example demonstrates the use of Waveform Click board.

The demo application is composed of two sections :

Application Init

Initializes the communication interface and configures the Click board.


void application_init ( )
{
    log_cfg_t log_cfg;
    waveform_cfg_t waveform_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.
    waveform_cfg_setup( &waveform_cfg );
    WAVEFORM_MAP_MIKROBUS( waveform_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == waveform_init( &waveform, &waveform_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    waveform_sine_output( &waveform, frequency );
    log_printf( &logger, "Sine wave output set with approx. frequency: %lu Hz\r\n", frequency );
    waveform_display_commands ( );
    log_info( &logger, " Application Task " );
}

Application Task

Predefined commands are inputed from the serial port. Changes the signal frequency, waveform or amplitude depending on the receiver command.


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

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.Waveform

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.

Heart Rate 11 Click

0

Heart Rate 11 Click is a compact add-on board suitable for heart rate monitoring applications. This board features the OB1203, a multi-channel light sensor (LS/CS), a proximity sensor (PS), and a photoplethysmography sensor (PPG) from Renesas. It can be configured as an ambient light sensor to measure ambient light similar to the human eye experience or as an RGB color sensor. The OB1203 establishes communication to and from the module entirely through a standard I2C compatible interface and has a fully integrated biosensor for reflective photoplethysmography.
