DTMF Generator Click is a compact add-on board that generates DTMF (Dual-Tone Multi-Frequency) signals designed for MCU interfaces. This board features the HT9200A, a dual-tone multi-frequency decoder mostly used in mobile communications systems from Holtek Semiconductor Inc.
We provide a library for the DTMFGenerator 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for DTMFGenerator Click driver.
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 );
This is an example which demonstrates the use of DTMF Generator Click board.
The demo application is composed of two sections :
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.

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. UART terminal is available in all MikroElektronika compilers.
