I have the Arty A7-100T and have successfully built and run a project using the PMOD RTCC module, which uses the I2C interface. I modified the project to use the I2C pins on connector J3 of the Arty and enabled the pullup resistors. I wired the SCL & SDA pins to the PMOD RTCC and all is good. It runs the same as if connected to the PMOD connector. So now I am trying to build my project without using the I2C defined port that is in the board definition files. I want to connect directly to the 6 control and data lines that make up the I2C port on the AXI IIC IP and I want to be

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.

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

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.

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 al

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:
