You need DAC connected to the 89C52 then you can program any waveshape you like.
It will be steppy because you will be outputing discrete voltages. You can make timer interrupt to update the output voltage value at fixed intervals depending on frequency required. You can also produce output waveform either by equation or by look up table depending on speed of your micro. Mahmood |
