    Zybo External LED Control

    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 external LED connected to the ZYBO through the command terminal. It seems I can connect a simple circuit with a LED and a resistor to the PMOD pins that are power and ground. What the command terminal would let me do is then essentially cut power to that pin, therefore turning the LED off. Please let me know if this is probable, and/or how I should task to complete it. Thanks, Russell

    Zybo I2c Master

    Hi, I have the Zybo Zynq 7000 board (Z-7010). I also have a Ti Msp430G2 launchpad. I need the Zybo to be the Master I2c , send request data from the Ti Chip. In Zybo i'm Using the I2c_0 Built in controller on the ps, i've tried the following Examples with no success(test failed Everytime): xiicps_polled_master_example.c xiicps_slave_monitor_example.c then i tried to to troubleshoot the problem, i'v used the xiicps_polled_slave_example.c and on the Ti Chip i used the wire library, as I2c Master and a c program that Scans Addresses - this works Therefor all the connections and vivado config are fine. How can find a working Master Program for zybo?

    Zybo I2C

    Hi, I have the Zybo Zynq 7000 board (Z-7010). I want to receive data from Multiple Devices via I2C protocol. In the PS there are 2 I2C Controllers. The Steps i made so far: 1) In vivado i created the ip : Zynq7 processing system. 2) i'v enables the I2C 0 controller and routed it to Emio. at this point i need 2 pins: clock and data, but instead i have 6 pins: where should i connect the pins? after Exploring this issue online i saw another option : using the Axi_IIc ip, With the same problem:
  4. Hello, I am trying to initialize the ADV7611 Chip of the Digilent FMC-HDMI add-on Board. But I can't find the needed addresses for it (this doesn't help). I am using the xiic.h Driver from xilinx. The initalization of ADV7511 Chip of the zc702 was successfully. Have anyone a idea?? I am using the zc702 and the digilent FMC-HDMI Card.
