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?
