DTMF Generator Click PID: MIKROE-4298 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.. The HT9200A tone generators can be instructed by an MCU to generate 16 dual tones and 8 single tones from its DTMF pin. It provides a Serial Mode interface, has a low total harmonic distortion and features a low current in the Stand-By mode. This Click board is suitable for various applications such as security systems, home automation, remote control through telephone lines, communication systems, and more. DTMF Generator Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board comes as a fully tested product, ready to be used on a system equipped with the mikroBUS socket.
