Waveform types: triangular wave, sine wave, square wave, sawtooth wave has a frequency, waveform display and set the type of function, that is, through the button settings specified frequency, the specified types of waveform output, and digital tube display frequency value and the waveform type. Output voltage: 0V ~+ 5V MCU controlled through the output waveform. Shown in the digital frequency control size. Through three buttons to control the waveform and frequency increase or decrease in the conversion. After came out from the single-chip D/A conversion. Digital signals into analog signals, resulting in the above observation of oscilloscope.
