staircase waveform

[javad]

hi. how can i generate staircase waveform with adjustable frequency,amplitude and numbers of stairs by keyboard????

[Ashutosh Bhatt]

use DAC with any microcontroller like AVR or PIC AT89C51

to vary frequency change the delay

to change number of steps change output voltage of DAC by changing digital input

do you have any program about this project?
