| Abstract: | DAC0832 understanding on the basis of chips,Implementation of the digital-to-analog converter. Through the internal structure,Control characters and the word means settingsof the 8255 A,Placement will be switching to the transmission of digital signals to analog converter DAC0832. Sine wave output can reach the final,triangle wave,sawtooth,pulse wave. According to switch input waveform switching,User operating arbitrariness. |
