hello, i am trying to blink the ledg[3] on the de2 Board with the following code but i don't have succes, i think that Problem is on (posedge iTD_VS) the V Sync output of the TV Decoder....how could i resolve it
assign oLEDG[3] = SW_RST;
reg SW_RST;
reg [1:0]SA;
reg [1:0]PRE_SA;
always @( posedge iTD_VS ) begin
if ( SA != PRE_SA )
begin
SW_RST = 0;
PRE_SA = SA;
end
else
begin
SA = iSW[17:16] ;
SW_RST = 1;
end
end

reg cnt;//6 bit for 50hz Vframe LED will blink with 50/64=0.8HZ. for 60 hz vframe LED will blink 0.94hz.
assign oLEDG = cnt;
always @( posedge iTD_VS ) begin
cnt <= cnt+1'b1;
end
