Clock Gen 3 Click

Clock Gen 3 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.

Example Description

This example demonstrates the use of Clock Gen 3 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ClockGen3

Example Key Functions

• clockgen3_cfg_setup Config Object Initialization function.

void clockgen3_cfg_setup ( clockgen3_cfg_t *cfg );

• clockgen3_init Initialization function.

err_t clockgen3_init ( clockgen3_t *ctx, clockgen3_cfg_t *cfg );

• clockgen3_set_cs_pin Sets CS pin state

void clockgen3_set_cs_pin ( clockgen3_t *ctx, uint8_t state );

• clockgen3_generic_write Generic write function.

void clockgen3_generic_write ( clockgen3_t *ctx, uint8_t *data_buf, uint8_t len );

• clockgen3_set_freq Sets Frequency

void clockgen3_set_freq ( clockgen3_t *ctx, float freq );

Application Init

Initializes the driver and configures the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    clockgen3_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.
    clockgen3_cfg_setup( &cfg );
    CLOCKGEN3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    clockgen3_init( &clockgen3, &cfg );

    clockgen3_config( &clockgen3, CLOCKGEN3_CFG_ON_CLK_180 );
    Delay_ms ( 500 );
}

Application Task

Sets different frequencies every 3 seconds and displays the set frequency on the USB UART.

void application_task ( void )
{
    log_printf( &logger, ">> Set Freq = 12.000 MHz \r\n" );
    clockgen3_set_freq( &clockgen3, 12000.0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, ">> Set Freq = 8.000 MHz \r\n" );
    clockgen3_set_freq( &clockgen3, 8000.0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, ">> Set Freq = 5.500 MHz \r\n" );
    clockgen3_set_freq( &clockgen3, 5500.0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, ">> Set Freq = 2.700 MHz \r\n" );
    clockgen3_set_freq( &clockgen3, 2700.0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, ">> Set Freq = 800 KHz \r\n" );
    clockgen3_set_freq( &clockgen3, 800.0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, ">> Set Freq = 200 KHz \r\n" );
    clockgen3_set_freq( &clockgen3, 200.0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, "---------------------------- \r\n" );
}

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.
