  1. Hi, I need to buy a pmod adc 8bits, i searched digilent, can only find 12bits. Do you guys have any recommendations? Thanks and regards
  2. Hi Tomy, Thanks for your explanation and help. i have tested it out for unipolar mode using the code provided by JColvin, https://reference.digilentinc.com/nexys4-ddr:xadcdemo, it works well with voltage below 1V. I have also built a circuit to limit the input voltage. Thanks and Regards Jeff
  3. Hi Sam, Thanks for your explanation and help. i have tested it out for unipolar mode using the code provided by JColvin, https://reference.digilentinc.com/nexys4-ddr:xadcdemo, it works well. I have also built a circuit to limit the input voltage. However, in my project, i would need to measure sine waves which requires bipolar mode, may i check how should i change the code to use the bipolar mode? Thanks and Regards Jeff
  4. Hi Colvin, Thanks so much for the reference, May i check what is the max input voltage the ADC can take? Thanks and Regards Jeff
  5. Hi guys. Am a newbie here, i am doing a software oscilloscope project using Nexys4-DDR Artix-7 using Vivado. I have tried to figure out how to start with the programming, am sorry to say that it is really difficult to me. I am thinking the most important part is to programme the ADC to read analog data, e.g. sine wave and pass it to PC. Not Sure if anyone have any ADC example project code that i can take reference to? Thanks very much for your helps. Appreciate it and Thanks
  6. Hi JColvin, thanks, i have downloaded the software.
  7. Hi all, Am new here, i just bought Nexys4-DDR Artix-7 board to start my software-based osciliscope project. May o know which software should i use to start my programming? thanks
