Tag: Phidgets

In the summer of 2017, Phidgets introduced a new driver library called Library 22 (Lib22). This replaced their legacy Library 21 (Lib21) software, and was rewritten from the ground up to provide support for their new VINT products, as well as greatly improve the reliability of wireless connections via a network host.

Unfortunately, Lib22 drivers are not backward-compatible with the Lib21 drivers used by earlier versions of Roastmaster. Roastmaster 11 (October 2017) requires Lib22 to be installed on your network host in order to connect to Phidgets.

Following are instructions for upgrading a Lib21 installation to Lib22. Detailed instructions for first-time installers can be found in Setting Up Phidgets.

SBC Host Users

1. Log into the administration console of your SBC
2. Navigate to System > Packages, and click “Refresh Available Packages”
3. Click “Upgrade All Packages”
4. Once the packages have been upgraded, click the “Install” button next to “Phidget22 Network Server” in the “Installable Packages” section
5. Next, navigate to Phidgets > phidget22 Network Server
   1. Verify that Phidget Network Server and PhidgetServer are enabled, published and running
   2. Verify Server Name and Port are entered
   3. Verify that Password field is blank
   4. Click Save Changes
6. Deactivate the old Lib21 package in Phidgets > phidget21 Webservice
7. Reboot your SBC in System > Reboot
8. Your probes should link in Roastmaster. If not, restart Roastmaster by double-tapping the home button. This will show all of the background apps. Swipe upward on Roastmaster’s screen to terminate it. Tap the home button again, and launch it as usual.

MacOS Users:

1. Download the Lib22 drivers for your operating system here.
2. Install the Phidgets Lib22 Control Panel application.
3. Open the Phidgets Control Panel application and:
   1. Verify PhidgetServer is enabled and published
   2. Verify Server Name and Port are entered
   3. Verify that Password field is blank
4. Uninstall the old Lib21 Preference Pane from System Preferences
5. Restart your Mac
6. Open the Phidgets Control Panel application and click “Start Network Server”
7. Your probes should link in Roastmaster. If not, restart Roastmaster by double-tapping the home button. This will show all of the background apps. Swipe upward on Roastmaster’s screen to terminate it. Tap the home button again, and launch it as usual.

Windows Users:

Installation instructions are similar to MacOS, with one major difference: If you use Windows Firewall (most users), Phidgets will need a firewall exception rule in order to communicate with Roastmaster. Otherwise, Windows will block the network traffic at the port level. You can do one of two things (short of disabling Window firewall–NOT recommended):

1. If you had previously created a Firewall exception rule: write down the previous port of the Lib21 that you were using before uninstalling Lib21. After installing Lib22, apply this port to replace the default port of 5661. Lib22 will then use the previous port exception in your firewall.
2. If not, add a Windows Firewall port exception rule for incoming and outgoing TCP traffic on the new PhidgetsServer port (usually 5661).

Upgrading Lib22

• Download the Lib22 drivers for your operating system here.
• Install the Phidgets Lib22 Control Panel application.
• Open the new Phidgets Control Panel application and:
  1. Verify PhidgetServer is enabled and published
  2. Verify Server Name and Port are entered
  3. Verify that Password field is blank
• Uninstall the old Lib21 Control Panel
• If necessary, add a Windows Firewall exception rule as outlined above
• Restart your PC
• Open the new Phidgets Control Panel application and start the Network Server
• Your probes should link in Roastmaster. If not, restart Roastmaster by double-tapping the home button. This will show all of the background apps. Swipe upward on Roastmaster’s screen to terminate it. Tap the home button again, and launch it as usual.

Verify Your Probes Can Communicate

Navigate to Probes in Roastmaster, and select each probe to view its details screen. Each probe should display a status of “Linked”. If not, your network host is not properly sending Phidget information across your WiFi network. Please visit Troubleshooting Phidgets for help resolving common issues, or instruction on how to get help.

Phidgets offer a versatile and scalable solution for monitoring and logging roast temperatures with Roastmaster’s Data Logging option. Roastmaster connects to one or more Phidget Temperature Sensors through your WiFi network via a network “host”.

Please see How Do Phidgets Work? to become acquainted with how a network host is used to communicate with Roastmaster. Or, see Phidgets for a list of supported Temperature Sensors and hardware.

If you are upgrading an existing Phidgets Lib21 installation on your network host to Lib22 for compatibility with Roastmaster 11, please see Upgrading to Phidgets Lib22 from Lib21.

Note: These instruction apply to Roastmaster 11 (October 20, 2017) which requires Phidgets Lib22 to be running on your host. If you are configuring Phidgets for an earlier version of Roastmaster for use with Lib21, please see Setting Up Phidgets Legacy Lib21.

To use Phidgets with Roastmaster, you’ll need…

1. A Phidget Temperature Sensor (one of the following)
   • Legacy Temperature Sensor
   • VINT Temperature Sensor and accompanying VINT Hub
2. Attached thermocouple or RTD probes
3. A network host computer to send wireless readings (one of the following):
   • A full-size computer, e.g. Mac or PC desktop or laptop
   • Phidget SBC with USB WiFi adapter
   • Another brand of wireless DIY computer
4. A wireless Ethernet network
5. Roastmaster’s Data Logging entitlement (available as an in app purchase in the “Probes” section of Roastmaster’s Utilities screen)

Once you have procured the necessary parts, you need to configure your host with the Phidget Network Server software drivers that allow it to communicate with Roastmaster on your wireless network.

Define Probes in Roastmaster

After configuring the network host, it’s time to define the probes you want to use in Roastmaster. This process is only performed once. After the probes are defined, they will be available for the life of the app on your device.

If you have not yet purchased the Data Logging option, you can purchase it by navigating to Probes, and tapping “Probe Store” in the bottom toolbar.

1. Navigate to “Probes” in Roastmaster.
2. Tap “+” to create a new probe.
3. Choose Phidgets Temperature Sensor.
4. Enter Temperature Sensor and probe configuration parameters (These are listed below according to Temperature Sensor and probe type)
5. Name the probe
6. Tap Save

SBC Host: Serial numbers of attached Phidgets can be found in the Phidgets > Status pane of the Administration Console.

Verify Connection

After entering all required probe information according to your Temperature Sensor and probe type as listed above, Roastmaster should display a green “Linked” status, as well as the current temperature of the probe.

If you see “Unlinked” displayed in red, and have followed all of these steps, it’s very likely that a firewall somewhere on your network (either on the host or the router itself) is blocking the Network Server traffic, or there is another configuration problem preventing the host from sending information to Roastmaster.

Please visit Troubleshooting Phidgets for a list of common connection problems and possible solutions.

Begin Using Your Probe!

Once your probe definition has been created, and displays a linked status, all that’s left to do in the future is to link the probe to reading curves in roasts to report temperatures and log data.

1. In “Roasts”, tap the “+” button to create a new roast.
2. Tap the curve button, and choose “Create New Curve”
3. Set the curve type to “Reading”
4. Tap the “Bind To” field to bind the curve to your new probe definition.
5. Save the curve

In the roast console, you can select your curve by tapping the console graph. Roastmaster will display live temperature readings as they change on the probe. After you start the roast, Roastmaster will log these temperatures at the interval defined in the curve for the duration of the roast.

Developing Your Workflow

Have a look at some of our screencasts, particularly those in the “Roasting with Roastmaster” series, for instructions on how to leverage curves and profiles with Data Logging to create effortless workflows with vital Reference Curves for targeting, and Data Curves for logging new data.
