I Have a group project at the moment, and right now I have to send a square wave to a Digital to Analogue Converter and output a voltage analog signal to a waveform, connnected to an audio amplifier afterwards I'm using a DAC MCP4922 : 12-Bit DAC with SPI™ Interface my professor said i also need e^(t/Time Constant) and sine(x) together to make a sound , how will I do this? is there a better way than using a lookup table to output the sine function Altera cannot compute sine functions , so how Will i solve this? are there any sample code i can use? Also, to use the DAC i have to interface it with the SPI, but I am new at this and i dont know where to start. How can I test out how the DAC works? any suggesstions and ideas i can go forward with it? I have no background in digital to analogue converters, and I want to get some testing done by the end of this week , i would appreciate any help available How do i get it to work what does it mean when a DAC is 12 bit?
