DTMF Generator Click

DTMF Generator 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 is an example which demonstrates the use of DTMF Generator Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log

Example Key Functions

• dtmfgenerator_cfg_setup Config Object Initialization function.

void dtmfgenerator_cfg_setup ( dtmfgenerator_cfg_t *cfg );

• dtmfgenerator_init Initialization function.

err_t dtmfgenerator_init ( dtmfgenerator_t *ctx, dtmfgenerator_cfg_t *cfg );

• dtmfgenerator_set_dat Set DATA ( RST ) pin state function.

void dtmfgenerator_set_dat ( dtmfgenerator_t *ctx, uint8_t pin_state );

• dtmfgenerator_power_on Power ON function.

void dtmfgenerator_power_on ( dtmfgenerator_t *ctx );

• dtmfgenerator_transmit_out_tone The function transmit duration time of the desired tone.

void dtmfgenerator_transmit_out_tone ( dtmfgenerator_t *ctx, uint8_t out_tone, uint16_t delay_m_s );

Application Init

Initialization driver enables - GPIO, run the power-on sequence, also write log.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    dtmfgenerator_cfg_t dtmfgenerator_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.

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.
