Using Standard Pmod in Zybo Zynq-7000 Development Board – Part 1

Objetives:

  • To show hardware configuration which is needed to access Pmod connectors in the Zybo Board
  • To make an application using Xilinx SDK which is allowed control external LEDs connected to the standard PMOD (JE) using el BTN0 (R18)

Tools:

You are going to need:

  • Vivado
  • Xilinx SDK

Main steps:

  • Create new project
  • Create block design
  • Configure IPs
  • Set constraints
  • Program software

The Zybo Board has six PMOD connectors, JF PMOD connectors is mapped directly to the PS that mean it can be used directly with the MIO interfaces, the rest of them have to be accessed using AXI Bus because they are in the PL space:

In this practice is used the standard PMOD (JE PMOD). the pin map is summarised in the penultimate column in Figure 1, to probe this we are going to develop the next hardware:

As the reader is aware, the Zynq is connected with the respective interfaces to IP AXI GPIO this allows Zynq to communicate with the PL through the AXI Bus. In order to prepare this hardware, we have to do the next step:
