V to HZ Click is a device that converts an analog voltage input signal into a pulse wave signal of a certain frequency. It has a linear response, so applying a voltage in a range of 0 to 5V on its input, will result in generating the pulse train with frequency linearly proportional to the input voltage.

V to Hz Click

Click library

  • Author : MikroE Team
  • Date : jan 2020.
  • Type : PWM type

Software Support

We provide a library for the VtoHz 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 VtoHz Click driver.

Standard key functions :

  • Config Object Initialization function.

    void vtohz_cfg_setup ( vtohz_cfg_t *cfg );

  • Initialization function.

    VTOHZ_RETVAL vtohz_init ( vtohz_t ctx, vtohz_cfg_t cfg );

Example key functions :

  • Generic sets PWM duty cycle.

    void vtohz_set_duty_cycle ( vtohz_t *ctx, pwm_data_t duty_cycle )

  • Stop PWM module.

    void vtohz_pwm_stop ( vtohz_t *ctx );

  • Start PWM module.

    void vtohz_pwm_start ( vtohz_t *ctx );

Examples Description

This application converts an analog voltage input signal into a pulse wave signal of a certain frequency.

The demo application is composed of two sections :

Application Init

Initializes driver and enables the Click board.


void application_init ( void )
{
    log_cfg_t log_cfg;
    vtohz_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.

    vtohz_cfg_setup( &cfg );
    VTOHZ_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    vtohz_init( &vtohz, &cfg );

    vtohz_enable ( &vtohz );
}

Application Task

Alternates between different output frequencies.


void application_task ( void )
{
    set_output_frequency( 1000 );        //1000 Hz output
    log_printf( &logger, "Output frequency: \t 1000 Hz\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    set_output_frequency( 2000 );        //2000 Hz output
    log_printf( &logger, "Output frequency: \t 2000 Hz\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    set_output_frequency( 5000 );        //5000 Hz output
    log_printf( &logger, "Output frequency: \t 5000 Hz\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    set_output_frequency( 10000 );       //10000 Hz output
    log_printf( &logger, "Output frequency: \t 10000 Hz\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}  

Note

Output frequency may vary depending on the offset and gain potentiometers on board the Click.

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.VtoHz

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.
