Hello, Merry Christmas hope you guys are doing great. I am a beginner in digital design course and i want to implement this xadc demo project from digilentinc reference on my Basys3 FPGA. I'm having problems on the step 4 which is running the project as i can't figure the physical connections to connect to the JAXDC port on FPGA. Can someone confirm if the connections i have done in this picture are right? One last question. When you open the XADC Basys3 Demo project and see its constraints, only package pins i don't understand are these A12,B13 ones. Where are they located on FPGA? I'm assuming there are some internal connections like seven segment decoder have. Any help appreciated. Thank You. Regards, Zain

Hello, I am kind of new to FPGAs and I am trying to use the XADC in order to monitor the temperature sensor: I am using Vivado 2018.2, Nexys video as a board. I used the IP catalog in order to set up the XADC as following: DRP, Single channel, continuous, disable all alarms, disable reset_in, channel to monitor: temperature I wrote a top level module which reads the bits 4 up to 7 from do_out and light up LEDs accordingly: //part of the top module: module top( input CLK100MHZ, input vp_in, input vn_in, input [1:0] sw, output reg [11:0] LED ); wire enable; wire ready; wire [15:0] data; reg [6:0] Address_in; xadc_wiz_0 XLXI_7 (.daddr_in(Address_in), //addresses can be found in the artix 7 XADC user guide DRP register space .dclk_in(CLK100MHZ), .den_in(enable), .di_in(0), .dwe_in(0), .busy_out(), .vn_in(vn_in), .vp_in(vp_in), .alarm_out(), .do_out(data), .eoc_out(enable), .channel_out(), .drdy_out(ready)); always @( posedge(CLK100MHZ)) begin if(ready == 1'b1) begin case (data[7:4]) 4'b0001: LED <= 12'b000000000001; 4'b0: LED <= 12'b0; 4'b1000: LED<=12'b000000000010; default: LED <= 12'b1; endcase end end ///// I have one problem though, as I come to set the address of the ddr_in as done in a documentation found here which has LEDs displaying potential differences monitored by XADC, I do not understand what 8 bit address I should assign for the DRP to monitor the Temperature Channel ! "Address_in <= 8'h ????" My goal: I need the LEds to display something for the sake of demonstration that I am able to read values out of the do_out. Thank you for your help.

Hi, I have used XADC IP Core on my Basys 3 board, I am unable to get updated value. i Keep getting 0V Can you please help me out with this. I have attacthed the block design and SDK Code.
