How to output multiple pulses? [Copy link]

Using the YF017 music chip in the picture below, different sounds can be played by sending out several pulses. Does the following code send out a single pulse? How can we send out multiple pulses to make this music chip send out different sounds?

always@(posedge clk)
begin
if(count == division/2)
begin
count <= 0;
beep_r <= ~beep_r;
end
else
count <= count + 1;
end

Yes, division is the frequency.

Just give different frequencies. You can search on Baidu. Different frequencies correspond to different sounds. There is a corresponding table.
