======Using I/O on Digilent Boards With LabVIEW LINX Toolkit======

===== Introduction =====

This guide will walk you through the process of deploying LabVIEW code to Digilent embedded targets for interacting with device peripherals and I/O, including digital, analog, SPI, I2C and UART. The following Digilent boards can be used with this guide:
 
  * Arty Z7-10  
  * Arty Z7-20 
  * Cora Z7-07S
  * Cora Z7-10

The LabVIEW LINX Toolkit adds support for Arduino, Raspberry Pi and BeagleBone embedded platforms. The Raspberry Pi provider is used to interact with the Digilent boards listed above.


----
===== Prerequisites =====
==== Hardware ====

  * Arty Z7-10 / Arty Z7-20 / Cora Z7-07S / Cora Z7-10 board
  *  Micro USB Cable
    * for UART communication 
  * SD card with a minimum capacity of 1GB storage
  * Ethernet cord

==== Software ====
  * [[https://www.ni.com/ro-ro/shop/labview/select-edition/labview-community-edition.html|LabVIEW 2020 Community edition (free for non-commercial use)]] 
  * Image file: [[https://digilent-file-share-public.s3-us-west-2.amazonaws.com/linx-debian-jessie-armhf-rfs.img.zip|linx-debian-jessie-armhf-rfs.img.zip]]
  * LabVIEW VI Demo Files for each board: {{reference/programmable-logic/guides/digilent_demo_labview_vi_files.zip|Digilent_Demo_LabVIEW_VI_files.zip}}
  * Software to create a bootable microSD card ([[https://win32diskimager.download/|Win32 Disk Imager]] is used in this guide)

==== Creating The Bootable MicroSD Card ====

  * Unzip [[https://digilent-file-share-public.s3-us-west-2.amazonaws.com/linx-debian-jessie-armhf-rfs.img.zip|linx-debian-jessie-armhf-rfs.img.zip]].
  * Start [[https://sourceforge.net/projects/win32diskimager/|Win32DiskImager]] and open **linx-debian-jessie-armhf-rfs.img**.
  * Select the drive letter of your microSD.
  * Click **Write**.

<WRAP GROUP> <WRAP COLUMN HALF>

Eject the microSD card and insert it into the slot on the board.

Connect the Ethernet cable between your board and the router.
Attach the microUSB cable between your PC and the board.

Open **Tera Term** and connect to the serial port of the board with 115200 baud rate, 8 bits, no parity, 1 stop bit.

On the first boot, the root partition on the SD card will automatically resize to make full use of its capacity. A reboot will follow.

==== Setup The Environment====

<WRAP GROUP> <WRAP COLUMN HALF>

Log in with the following:
<code>
Username: linx
Password: linx
</code>

=== Library setup ===

Out of the box, the environment is configured for the Arty Z7-20. If you are using one of the other boards, run the following commands:
<code>
cd /srv/chroot/labview/usr/lib/
sudo ln -s --force <BOARD SO FILE> liblinxdevice.so
</code>

Where **__<BOARD SO FILE>__** is:
  * liblinxdevice_az710.so for Arty Z7-10
  * liblinxdevice_cz707s.so for Cora Z7-07S
  * liblinxdevice_cz710.so for Cora Z7-10

Verify the symbolic link is set correctly:
<code>ls-l liblinxdevice.so</code>

<WRAP GROUP> <WRAP COLUMN HALF>

If you pointed the symbolic link to a different library, restart the LabVIEW service:
<code>sudo systemctl restart labview.service</code>

Find out the IP address using the command: <code>ip a</code>

You can access the board I/O from the interface. 


{{ :reference:programmable-logic:guides:labview9.png |}}

**NOTE**: In this demo:
  * IO0-13, IO26-I042, JB1-JB10, JA1-JA9 and LD0-LD3 are output channels (DO Channels)
  * SW0-SW1 and BTN0-BTN3 are input channels (DI Channels)
  * There is one channel for SPI, one for I2C and one for UART (Channel 0).
  * The demo is configured to read over SPI or I2C protocol and to read/write over UART protocol.
  * The SPI is configured to read one byte by sending a multibyte structure (3 bytes) wherein the first byte is a command, the second byte is the SPI Register Address and the third byte is 0x00. The user must adapt the block diagram  of the Demo_<name-of-Digilent-board_>.vi for the SPI device that is using.
  * The A6-A7 differential channel is a unipolar channel and A8-A9, A10-A11 and V_P – V_N are bipolar channels. Please read the [[https://docs.xilinx.com/v/u/en-US/ug480_7Series_XADC#G5.287835|XADC User Guide (UG480), Page 31]] for more information.

--> Cora Z7-10 and Cora Z7-07S Pinout #


The Cora Z7-07S board pinout is the same as the Cora Z7-10 board pinout. The only difference between Cora Z7-10 and Cora Z7-07S is the capability of the Zynq part.
----



NOTE: The Cora Z7-10 board is compatible only with the **liblinxdevice_cz710.so** library.


NOTE: The Cora Z7-07S board is compatible only with the **liblinxdevice_cz707s.so** library.

=====Additional Configuration To Chroot=====


You can get a command shell inside the LabVIEW chroot by using SSH or UART communication. 

Make sure labview.service is running <code>systemctl status labview.service</code> otherwise restart it <code>sudo systemctl restart labview.service</code> then run <code> sudo schroot -c lv -r </code>

This will create a new shell within the chroot. From here you can examine the file system and run other commands in the same environment that the LabVIEW run-time engine is running in. When you are finished, you can run <code>exit</code> to return to the normal shell.

There is the possibility to install some software to the LabVIEW chroot on the target.

  - Make sure your target has an internet connection.
  - Access a shell within the chroot (see above).
  - Run <code>opkg update</code> to get the list of available software. If you get "wget bad address", run the following command to configure the network interface: <code>/etc/init.d/networking start</code>
  - You can list the available software by running <code>opkg list</code>
  - When you find something you'd like to install, run <code>opkg install <package_name></code>

There are a number of packages available, for example:
  * **packagegroup-core-buildessential** which installs the gcc compiler and tools like GNU make
  * debugging tools: **gdb**
  * libraries: **opencv**
  * programming languages: **python**.
