| Abstract: | A design of waveform generator based on CPLD and SCM is introduced.Under MATLAB Simulation environment,the arbitrary waveform generates principle and realizing method.The waveform generator is used as a controller of SCM AT89S51.Frequency divider and address generator are achieved by the CPLD,the output of the digital signal comes from DAC 0832 converting analog signals obtained.The amplitude of waveform and the controlling of frequency are achieved through keyboard circuit and progaming in SCM. |
