    Download and install Etcher
    Run Etcher
    Select the PiDash Image you downloaded
    Select the drive of your SD card
    Click Flash!

  • For Linux users
  • Find the device (eg: /dev/sdb1) you need to write to by using blkid or mount.
    Double check that you have the correct dev path for your SD card (eg: /dev/sdb1).
    Unmount the SD card and all its partitions by using umount /dev/sdb?.

    Decompress the file:

    tar xf “PiDash image file.tar.gz”

    Write the image using the below command.

  • PiDash Network Troubleshooting

    Posted on by Alex

    This page assumes:
    1. You’ve used Config WIFI to setup your connection. If not, please go do so.

    There are several reasons you cannot connect.
    1. Incorrect spelling of your home/shop/whatever hotspot you’re trying to connect to.
    2. Incorrect key used (WEP, WPA-PSK).
    3. Typo in your password.
    4. All of the above is fine, but your Windows box says it cant connect. What gives?

    To test wireless settings, go ahead and click on “Enable Network”

    Click on Terminal which will open up LXTerminal.

    Type the following command. You will see a list of hotspots your PiDash can see. Use the scroll bar on the right to scroll up if needed.

      iwlist scan |grep -i ssid

    What you’re looking for is YOUR HOTSPOT. Lets use “2WIRE732” as an example, we’ll say this is your hotspot. Make sure you typed it correctly in Config WIFI, just as it is shown in that command output. In Config WIFI, it will need to be IN QUOTES along with your password. If this is correct, keep going.

    Next thing to check is, which key_mgmt value you need to use in Config WIFI. In the same terminal session type:

      iwlist scan

    Scroll thru that list and find YOUR HOTSPOT, in my example it is “2WIRE732”. They all start with “Cell XX”.
    What you’re looking for is if it says WEP, or WPA/WPA2 and then the Authentication Suite. In my example it says PSK. Then go back to Config WIFI and use 2WIRE732 (with the quotes) for YOUR SSID, WPA-PSK for key_mgmt (that is the default in the template), then finally YOUR WIFI PASSWORD for psk (in quotes).

    If you CAN connect to the PiDash either with Direct or via WiFi but cannot access the PiDash Share

    There have been instances of Windows systems not being able to hit the PiDash either the “Enable Direct” option or “Enable Network” option.
    Most instances are because Enable Guest Logins is not enabled. To enable that do the following:

    Re-Enable the guest account fallback for SAMBA:

    1. Go into Local Group Policy Editor
    2. Navigate into Administrative Templates – Network – Lanman Workstation.
    3. Then the Setting : Enable insecure guest logons has to be set to “Enable”.
    Enable : Allow guest usage and solve the problem
    Disable : Will not allow guest usage and provide this problem.

    Ensure that WiFi Direct is not enabled by clicking on Disable Direct on the desktop.

    The new method with WiFi Transfers is using a GUI application called Wicd. You will need to click on ENABLE NETWORKING BEFORE continuing. Always make sure to DISABLE NETWORKING when done and then click DISCONNECT from wireless in the Wicd application.

    There are two methods which you can access this application.

    Bottom right corner there is an icon with two desktops. Left Click once.

    The second way to access this screen is to go to the menu on the bottom left.

    Wicd WiFi screen is shown.

    You will NEED TO KNOW THE FOLLOWING. The wireless connection you’re trying to connect to, the password and the encryption type. You will get all of this information from your router.

    In the below screenshot WPA 1/2 is a dropdown. Select the type of encryption you have set in your wireless router.
    Key is your wireless password. To make sure you type it in correctly, click on the checkbox. Once done, hit OK.

    After you hit OK, you will be back at the main screen. Find your hotspot and click CONNECT.

    You will be connected if your information is entered correctly. Your IP that you will connect to from File Explorer in Windows will show up where indicated by the red arrow. You will also notice the icon on the bottom right is green. MAKE SURE YOU CLICK DISCONNECT WHEN DONE, otherwise WiFi Direct will NOT WORK.

    (This page is updated as I get time and/or fix bugs/add features)

    • PiDash by AB NEWS

    04/30/2021 BUG FOUND in GPS Time. For now, dont use it. I recommend using an RTC module. Please look at this pic. RTC module is the red board. What does this mean? I means that if you enable GPS Time, the MPH feature in TunerStudio will not be read from your GPS module. So dont use GPS Time if you want to use MPH. It also means your LOG FILES will have a weird date from the past. You might be able to use “Silently auto name log files” feature in TS though.

    03/06/2021 06/14/2021 Add support for a RTC (Real-Time Clock). I’m finding acquiring GPS time is too slow. **Already done, need to add to new build** New build will REMOVE GPS Time issue listed above!

    06/14/2021 I am going to build an Arduino based dash. It will be display only for now and TEXT only. Meaning, nothing fancy, just numbers and text. Clickie here.

    06/14/2021 Also, added a 3.5″ touchscreen just for the hell of it. Clickie here.

    06/30/2021 Working on an Arduino + CAN BUS Hat + Nextion 7″ display text based dash. This will take priority over making a Raspberry PI based CAN BUS dash. Check it out here!

    • OLD NEWS – news from above rolls down here and eventually gets deleted.

    03/06/2021 Made changes to the Updater. Added indicator lights to show what is enabled and disabled. Added “C”onfigure buttons to GPS Time and Mausberry. Cleaned up some code to make sure services are enabled/disabled correctly. Please watch the video here for usage.
    Click here to for Updater install notes.

    03/14/2021 Updated this page. There are docs/links that no longer are relevant to using PiDash by AB. The Updater handles pretty much everything. While the links may still be there, please watch the latest video. Join the Facebook page also for help.

    How to install, configure and use PiDash

    Slow boot time
    1. If you forget to disable WiFi Direct or WiFi Networking, your PiDash will probably take quite some time to boot up. When you do boot up, minimize or exit TunerStudio and click on Disable Direct or Disable Network. Please use the latest version and the Updater app and make sure Networking options are disabled.

    I cannot see my tunerstudio_share and I’m using Windows 7
    You might need to manually mount if it does not work from File Explorer. You will do it like so:

    net use Z: \\\tunerstudio_share

    Then head back to File Explorer and find the Z: drive. Double click and there you go. If you already have a Z: drive, pick a letter you dont have, like Y: or X:

    WiFi Networking PRE 1.5.2- I cant connect to my wireless router from PiDash!
    How to Configure/Troubleshoot WiFi Please watch the latest video on how to connect to a network. Use the latest version and the Updater app.

    WiFi Networking 1.5.2 Instructions
    PiDash Wicd Networking Please watch the latest video on how to connect to a network. Use the latest version and the Updater app.

    Where do I put my Project/Tune Files?
    There is a directory called TunerStudioProjects. This is the only location you should put them in otherwise you may have permissions issues transferring files. Its not a show stopper so I’ll probably fix that next version.

    Why doesn’t my version of TunerStudio auto shut down when I exit TunerStudio?
    TunerStudio Ultra (beta) has a feature where you can set a button on your dash to shut down the PiDash by clicking or touching (if you have a touchscreen) the button. You must configure that manually.
    If you do not have TunerStudio Ultra (beta), you will need to exit TS and click shutdown. I will be making a feature to enable auto-shutdown on TunerStudio exit for the users who do not wish to buy TunerStudio Ultra.

    What if I just power down my PiDash without shutting down with the Shutdown icon?
    Well…the filesystem will probably save your butt on next boot but the problem is, you may lose your datalog you just created.

    What if there is a feature I want, how do I ask for it?
    Email me or post up on the Official PiDash Facebook page.

    My clock is wrong! What gives?
    Unless you have a RTC (Real-Time clock) module, your time will be off. In order to sync the clock, first connect to the network and then click on the Command Line icon (bottom left, black monitor icon) and type the following:
    **You may need to reboot after connecting to the network for this to take effect**
    **If your time doesnt change within 30-40 seconds, reboot WITHOUT clicking on the Disable Networking icon. **

    systemctl start systemd-timesyncd.service
    systemctl daemon-reload

    Then do what you need to do and then disable it.

    systemctl stop systemd-timesyncd.service
    systemctl daemon-reload

    • Miscellaneous questions

    I’m running Raspbian/DietPi/Debian and I just want to make your changes to my version. How?
    Most is documented on this site, go thru it. SAMBA, WiFi Direct and WiFi Networking is available via google. Why I configured what I did, too tired to rehash. You’ll need to figure it out.
