Clock Gen 2 Click

Clock Gen 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

• Author : MikroE Team
• Date : Dec 2019.
• Type : I2C type

Software Support

Example Description

This application enables generation of square waved clock signal in range from 260 kHz to 66,6 MHz

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ClockGen2

Example Key Functions

• clockgen2_cfg_setup Config Object Initialization function.

void clockgen2_cfg_setup ( clockgen2_cfg_t *cfg );

• clockgen2_init Initialization function.

err_t clockgen2_init ( clockgen2_t *ctx, clockgen2_cfg_t *cfg );

• clockgen2_default_cfg Click Default Configuration function.

void clockgen2_default_cfg ( clockgen2_t *ctx );

• clockgen2_output_enable Function for enabling/disabling of the clock output.

void clockgen2_output_enable ( clockgen2_t *ctx, uint8_t state );

• clockgen2_auto_setting_preserve Function used for enabling/disabling auto settings preservation.

void clockgen2_auto_setting_preserve ( clockgen2_t *ctx, uint8_t state );

• clockgen2_set_prescaler Function for setting the main clock prescaler.

void clockgen2_set_prescaler ( clockgen2_t *ctx, uint8_t val );

Application Init

Driver initialization.

void application_init ( void )
{
    log_cfg_t log_cfg;
    clockgen2_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.

    clockgen2_cfg_setup( &cfg );
    CLOCKGEN2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    clockgen2_init( &clockgen2, &cfg );

    Delay_ms ( 100 );
}

Application Task

Changes the prescaler and enables/disables the clock output.

void application_task ( void )
{
    //  Task implementation.

    char i;
     
     for ( i = 5; i< 8; i++ )
     {
       clockgen2_set_prescaler( &clockgen2, i );
       clockgen2_output_enable( &clockgen2, 1 );
       Delay_ms ( 1000 );
       Delay_ms ( 1000 );

       clockgen2_output_enable( &clockgen2, 0 );
       Delay_ms ( 1000 );
       Delay_ms ( 1000 );
     }
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
