To achieve a simple function of the signal generator. System power-up, the default output low (no waveform), the default initial frequency of 1 kHz. Waveform output frequency by the development board DIP switch SW0 ~ SW3 adjustment, adjustable range 1KHz to 2KHz, stepping amount 100Hz. Waveform output by the development board DAC_A mouth. Total square wave and triangular wave, sine wave three waveforms to choose from, users simply the development of on-board DIP switch SW6- SW7 set to different values of a combination of different waveforms can be output. The duty cycle of the square wave with the key switch on the development board BTN0 ~ BTN1 regulation. System reset button for the development of the key switch on the BT7. In addition, after the acceptance of the experiment, I continue to add sawtooth output.
