How do I resize a partition on the SD card in my module?
This is covered in our Application Note, AN-117, found in the Application Notes section in the G2H Software Documentation.
Does the CAN bus on the G2 modules support the CAN 2.0 specification?
Yes, our controllers with the CAN option support the CAN 2.0B protocol specification.
What are the reserved I2C device addresses on the display module?
Reserved I2C devices addresses vary based on the module. Find G2C1 and G2H2 addresses in the tables below. G2C1 Reserved I2C Device Addresses G2H2 Reserved I2C Device Addresses NOTE: Bus 0 is an internal I2C bus. Bus 1 is available on connector J21 (full-stuff modules only).
Is it possible to run the G2H2 network over a USB-Ethernet adapter?
It is luck-of-the-draw on whether the driver in our kernel supports any given USB-Ethernet adapter or not. The adapters use one of many different controllers, and some might work while others do not. Even if you find one that works, you might not be able to get the exact module again because the vendor will change the internal controller. Because of this driver/controller issue, we don’t support the USB-Ethernet feature.
When I try to connect to the display module using G2Link, I get a Windows pop-up saying I need to enter my network credentials.
This issue rarely occurs, and it is due to an unknown configuration setting in the Windows system. We have not been able to determine why this occurs, but we have a workaround, which is to add a Windows credential for the display module. Use these steps to add a credential: Open Control Panel. Click on “User Accounts”. Click on “Manage Windows Credentials”. Click on “Add a Windows Credential”. In the new window, enter the display module’s IP address, enter ‘root’ for “User name:” and leave “Password:” blank. Then click on OK.
How can I fix issues connecting to the display module via G2Link. I have a valid IP address and I can ping it, but I cannot publish my project nor display folders.
Microsoft recently changed their security policy to use Samba 2.0 instead of Samba 1.0, and have disabled Samba 1.0 by default. Our module uses Samba 1.0. Use the steps below to enable Samba 1.0, and this should fix the issue. On Windows 10, starting with build 1709, Microsoft has deprecated and disabled SMBv1 in favor of v2 for security reasons. This will cause G2Link to get an error when trying to Publish and Run a QML application, saying that the path does not exist. If you see this error, you can check which build of Windows 10 is on your system with the “winver” command. It will give you a screen such as: Note: The above screenshot is showing Version 1607 instead. If your system is showing version 1709, you can use the steps below to work around the problem. Start Control Panel, click on Programs, then in Programs and [...]
Why is there a Windows and a Linux Development Kit package?
All the development kit hardware and software to prototype a touchscreen display is the same, however, the Qt Development Software is geared toward either Windows or Linux users. Linux Quick Start Guides Windows Quick Start Guides Note to Windows Developers: While our touchscreens are Linux-based – that doesn’t mean you need to be a Linux developer to use them. Our solution allows developers to use Windows GUI tools to develop their application and then load it into our display controller to run. Write a complete graphical interface, test it out on the PC, and then drag the application over to our display module’s file system to run. It runs the same as on the desktop. Reach has developed a suite of drag-and-drop interface components for quick prototyping. Whether you develop in Qt or QML, you can run the same code on the PC or the target. Reach does all [...]
Which Linux distribution is running on the display module?
G2 modules run a custom Linux distribution (build) Reach Technology created. Since standard distributions come packaged with many components and packages not required on our display modules, it is not based on any standard Linux distribution.
Is there an editor available with macro syntax highlighting?
Thanks to one of our customers, there is a way to edit your SLCD macro files and have syntax highlighting. The TextPad shareware editor can do the custom highlighting. Download this ReachMacros.syn file and follow these instructions. You should now see macro highlighting in TextPad. Please note that Reach Technology is not responsible for supporting this file.
Is there an easier way to get BMP images and macros onto production units without having to manually load each one using the Flash drive?
Yes, we can pre-load BMP images and macros to production display modules and enclosed units for a nominal fee. Contact our sales team for a quote.
