Hi all,
I am in trouble with ADC module. I try to code a very simple code:
module dac_test(
input clk,
output [13:0] dac
);
assign dac = 14'b11110001010110;
endmodule
with clk is 1Mhz clock and I mapped it into PIN_B15, and the 14bit data dac, I mapped it into 14 pin of U14. I sure that after I install like this, I totally get the logic level in U14's pins as in the code, and I also check the clock at pin 28 of U14. It is OK.
However, I use the VOM try to get the analog output voltage of DAC (DAC), but I always got the same level of DC 0.45V. It's always the same when I try to change the input data. I dont know why...
Pls help me how to check and use this DAC module on this board.
Thank you
