I have a school project with DE2 board & Verilog code, and we're going to make something like a sound generating machine. It is kind of JUKE BOX. First of all, I want to make single tone sound, like beep sound. For Example, when I push KEY 1 , DE2 board sounds (like beep!) To make this function, how can I get some information? Any body Help me Plz !

Sin wave generation can be lookup table based or algorithm driven (like CORDIC). Then configure onboard ADC and keep sending samples sequentially. Hope this helps
