The ComfilePi is an industrial Raspberry Pi touchscreen panel PC.

The Raspberry Pi is a compact single board computer made in the U.K. by the Raspberry Pi Foundation. It typically runs the Linux operating system.

The Raspberry Pi, as typically sold by the Raspberry Pi Foundation as a credit-card sized PCB, is primarily a tool for students and hobbyists. Although it is a fantastic and even revolutionary product, it may not be suitable for certain industrial applications.

The Raspberry Pi Foundation released the Raspberry Pi 3 Compute Module so 3rd party manufacturers could build industrial devices around the Raspberry Pi technology, and the ComfilePi is exactly that.

(*) The current 7“ and 10” hardware revision was designed for a built-in RTC, but the components are not populated. If you'd like the ComfilePi 7“ or 10” models with a built-in RTC, please inquire by sending an e-mail to sales@comfiletech.com. A future hardware revision is planned to have the built-in RTC included by default.

Download the Raspbian OS Image - An SD card with a slightly modified Raspbian Linux distribution is included with each purchase.

Warnings and Precautions

The 40-pin header socket on the rear panel of the ComfilePi is almost the same pinout as the Raspberry Pi 3 Model B's I/O header.

The GPIO pins are exposed through a transparent (3.3V ←→ 3.3V) level shifter for ESD protection. For electrical characteristics please see the level shifter's data sheet : TXS0108E.

See also the CP-IO22 and CP-IO19R IO board accessories.

The underside of the ComfilePi exposes 12~24VDC power input, 2 RS-232 serial ports, 3 USB 2.0 ports, an I2C port, 5V power output, and an RJ45 Ethernet port.

The right panel of the ComfilePi exposes a MicroSD Card Slot and a stereo audio output jack.

As of August 14, 2017, you can now develop .Net Core 2.0 applications for the ComfilePi. See .Net Core on the Raspberry Pi for more information.

• Running .Net WinForms Applications with Mono - .Net applications can run on Linux by utilizing the Mono framework. WinForms applications can be developed and debugged on a Windows host PC using Visual Studio, and simply copied to the ComfilePi and executed; no re-compiling required!
• Modbus with NModbus4 - A demonstration using the ComfilePi as a Modbus RTU master, with NModbus4, to control a PLC.
• Hiding the Mouse Cursor - There is typically no need for a mouse cursor in a touch application, but the ComfilePi and Mono give you one anyway. This explanation will show how to hide the mouse cursor.
• Programming the SerialPort - A few considerations to keep in mind when using programming the serial ports.
• Programming the GPIO - An demonstration illustrating how to program the ComfilePi's GPIO using the CP-IO22 add-on board.

Microsoft added limited Linux support to Visual Studio 2015. Those features also available in Visual Studio 2017.

The Visual Studio Linux Features do not inherently support cross-compiling on a Windows PC. Instead, Visual Studio will upload the the source files to the ComfilePi, and use the ComfilePi's toolchain to build the executable. The executable is then executed on the ComfilePi, and the Visual Studio Remote GDB Debugger attaches to it.

1. Install Visual Studio Linux Features - How to install the Linux Development Features in Visual Studio 2015 and Visual Studio 2017
2. Create a Linux Project - How to create a new Visual Studio Project for Linux Development

For more information about using Visual Studio for Linux software development, see thisVisual C++ For Linux Development blog post, and the Visual C++ Linux Documentation.

NOTE: Comfile Technology does not provide technical support for Qt; please contact The Qt Company for support.

This procedure makes use of Qt's open source distribution. Please see Qt's Licensing, FAQ, and Licensing Comparison for more information about Qt licensing.

1. Install Qt Creator - Qt Creator is the IDE that will be used for developing Qt software.
2. Install the ComfilePi SDK - COMFILE Technology has created an SDK that contains all necessary components for compiling and debugging ComfilePi a Qt project with a Windows PC.
3. Test a Qt Quick Example Project - After Qt Creator and the ComfilePi SDK have been installed, open a sample project, deploy it to the Comfile Pi, and debug it from within Qt Creator
4. Create a New Qt Quick Project - Start from scratch: Create a new project, deploy it to the Comfile Pi, and debug it from within Qt Creator

• Modbus with Qt - The Qt Modbus component supports both Modbus RTU and Modbus TCP. Examples with Qt Widgets and Qt Quick.

For more information about software development with Qt, see the Qt documentation.

NOTE: The build of Qt used in this demonstration uses the EGLFS backend. Be sure to set the ComfilePi's GPU memory to 256MB or you may experience errors or display anomalies.

This procedure describes how to create JavaFX applications for the ComfilePi using the Oracle JDK and OpenJFX.

1. Install the Oracle JDK and OpenJFX - Install the Oracle JDK and OpenJFX framwork on the ComfilePi.
2. Install NetBeans - Install and Configure the NetBeans IDE on a development PC.
3. Test a JavaFX Example Project - Use the NetBeans IDE to open an example JavaFX project, configure the Java platform, deploy the project to the ComfilePi and debug it in NetBeans.
4. Fixing Multiple Touch Events in JavaFX - If you experience multiple touch events for a single touch while using a JavaFX application, please follow these instructions for a workaround.

For more information about software development with JavaFX see the Oracle JavaFX documentation.

• Configure a Program to Auto-Start - Most embedded applications do not run in a desktop environment. This procedure will describe how to configure the ComfilePi to boot to a console instead of a desktop environment, and auto-start a program as a service.
• Controlling the Piezo Buzzer - The ComfilePi has a built-in Piezo buzzer. By default, it beeps when touched. This feature can be disabled and/or the piezo buzzer can be used for other purposes.
