📞 Using Matlab to simulate Dual-Tone Multi-Frequency (DTMF) of telephone

Dtmf generator for stm32

DTMFDuino receives DTMF tones through a MT8870 integrated circuit who converts the analog audio of tones to a binary code understandable by the microcontroller. The microcontroller runs Arduino bootloader and converts the received codes to actions (turn on and off some outputs), also the system has the option to know the current state of each output.
