Detailed Description

DTMFDecoder Click example.

Description

This example shows the basic tone capture of DTMF frequencies, decoding and representing them on the UART LOG.

The demo application is composed of two sections :

Application Init

Initializes I2C and UART LOG drivers and powers on the device.

Application Task

Checks the delayed steering for incoming tones and decoding them on the UART LOG. Holding the same key will recognize multiple tone generation, the tone register delay constant can be set to adjust the tolerance.

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 LOG_MAP_USB_UART macro definition for detailed explanation.
