  1. Is this in Vivado under constraints? I have never made a constraints file before. I believe it made me an xdc file when I set the scl and sda pins to pull up and what not. Would I add it in there? Thanks, Russell
  2. Hello All, I am having an issue with running the Master Polled example on I2C with the zynq. I have a base design that is set up and runs the self test and repeated start examples and completes them. My issue is that I hooked up an I2C sensor, added pullup resistors, and it is failing. The only thing I have changed in SDK is that I have found the address of my I2C sensor, 0x57, and put it in place of 0x55. I can place my block design and what not here for referencing. Update - I have assigned I2C pins to W19 and W20 to SCL and SDA respectively.
  3. Hi all, New to the FPGA world as I was tasked a project to help familiarize myself with the programming and function of how FPGAs work. As you can all infer, I am in need of some help on a specific project that I am doing. I am using a ZYBO Zynq 7000 development board, and Vivado 2019.1. What I am trying to do is control an external sensor, or LED through some user interface. I have seen a lot of tutorials that use the on-board LEDs, and if you press a button, it displays that value in binary in a command terminal. My task that I was to do is be able to turn on and off an exter
