What You Will Find In Your G2H2 Kit
Congratulations on getting a G2H2 Development Kit. We would like to show you around.
In addition to the display module, here are the items you’ll find in your G2H2 kit. Additional accessories can be purchased online should you need them for prototyping or to replace items that have broken.
Watch this video to see how to set the G2H2 module up for basic operation.
These items will come into play later in development.
Let’s Get Started
To start the demo:
You will be greeted by a boot screen:
When the boot process is finished, you will be presented with a screen with several Qt demos showing various supported features. To scroll through the G2H2 demos, use the buttons on the right (best with resistive screens) or the swipe area on the left (best with capacitive screens).
Let’s Get Coding
We suggest you run one of our sample applications to begin writing your own code.
Reach provides a Linux Development Virtual Machine (VM) with all the tools you need to develop a display module. The virtual machine is created with VMware Workstation version 9.0.
To run the VM, you need to download the latest version of the VMware Player. Navigate to VMware, select Downloads, and then select Player. For the Major Version select the latest version and then click Download for your host architecture and operating system.
Launch VMware Player and select Open a Virtual Machine. Navigate to the location of the Reach Linux VM and select the .vmx file. Now click on Play virtual machine. If you see a message about moving or copying the VM, click on the I Copied it option.
On the Virtual Machine Desktop you will find the following tools:
Once installation is complete, connect the Development Kit Connection Cable (Part Number: 23-0161-72) to the Development Kit Connection Port “DEBUG” on the module. Next, plug the Development Kit Connection Cable into an open USB port on your PC.
There are two choices for connecting the display module to your network; wired/Ethernet and wireless/WiFi. The wired solution simply plugs into your router using an Ethernet cable (Part Number: 23-0148-12) connected to the “ETHERNET” connector (and possibly the Ethernet Coupler and a user-supplied Ethernet cable). To connect via WiFi, plug the WiFi Dongle into the Standard USB Adapter, and attach the adapter to the USB Host “USB H1” on the display module. Once these connections are made, power on the display module. See the Networking page for more details.
To write C/C++ applications that will run on the display module, the source must be compiled with a cross compiler. The cross compiler is installed in /opt/reach/1.6.3. The 1.6.3 directory contains the script environment-setup-armv5te-reach-linux-gnueabi. This script, once sourced (with the source command), adds the correct paths to the environment for cross compilation.
When you’re ready to deploy your application to the display module, see the Linux Deploy page for more details.
An Important Note
Your development kit ships with two microSD cards. Keep one of the cards as a backup so that you can always run the demo apps. DO NOT edit files on the backup SD card as you might not be able to get the demo applications running again.
