大家帮看看这小段代码为什么 蜂鸣器一直响啊?我想让他响1/3时间周期,不响2/3,循环.查了好久啊,高手帮帮忙
feng接到蜂鸣器上,feng=0开始响

module zoumadeng(clk,feng);
input clk;
output feng;
reg feng;
reg [26:0]count1;
always@(posedge clk)
begin
count1<=count1+1;
if(count1==30000000)
feng=0; / _ring
else (count1==90000000)
begin
feng=1; //ring
count1=0;
end
end
endmodule
