The CCGX is based on the Technexxion board TAM-3517, which is using the Texas Instruments Sitara AM3517, containing a ARM Cortex-A8 microprocessor:

CCGX image / distro is based on Poky.

Poky can be thought of as a reference distribution. It is maintained by an organisation called the Yocto Project and based on Open Embedded.

Taken directly from the Yocto Project website (www.yoctoproject.org): “…The Yocto Project™ is an open source collaboration project that provides templates, tools and methods to help you create custom Linux-based systems for embedded products regardless of the hardware architecture“. Some of their projects that are relevant to the CCGX are Poky and Bitbake.

Open Embedded is a build environment for embedded linux, and has all kinds of tools, mechanisms and recipes to build the Linux kernel and make a full embedded Linux rootfs. Maintained version are listed here, https://wiki.yoctoproject.org/wiki/Releases.

To build the distro yourself, see: https://github.com/victronenergy/venus

we are using a mixture of C, C++, QML (for the user interface) and Python. As a main data exchange, to share values such as voltages, as well as settings and other data, we use D-Bus. D-bus is for inter process communication, see google and the D-Bus page on wikipedia for more information. This diagram gives a good overview of the whole thing:

Processes that interface to products, using the different protocols. These processes make the information available on the D-Bus.

• VE.Can to dbus
  written in C, reads and writes to the VE.Can comm. port.
• mk2dbus
  written in C, reads and write to VE.Bus (Victron inverter/charger protocol).
• VE.Direct to D-Bus
  written in C, reads/writes to serial connected devices, such as the BMV and MPPT solar chargers.
• gps_dbus
  also written in C. Open source: https://github.com/victronenergy/dbus_gps.
• dbus_qwacs
  C++, using the QT library. Reads data from wireless AC sensors connected via an Ethernet-DECT gateway. Open source: https://github.com/victronenergy/dbus_qwacs
• dbus-fronius
  written in C++, communications to Fronius PV inverters via LAN/Ethernet. Open source: https://github.com/victronenergy/dbus-fronius
• dbus-motordrive
  https://bitbucket.org/oceanvolt/dbus_motordrive

• gui
  Written in C++ and QML, uses QT. Takes care of the user interface: buttons and the display
• vrmlogger
  Written in Python, takes data from the dbus and submits it to the VRM Portal. https://vrm.victronenergy.com/
• localsettings
  Written in Python, takes care of user settings. All other processes read and write their settings through this daemon via D-Bus. The daemon is an interface between D-Bus and the file /data/conf/settings.xml. Open source: https://github.com/victronenergy/localsettings.
• dbus_modbustcp
  Written in C++, uses QT. Modbustcp server that can be used to access data of all products connected to the CCGX. See our Data communication whitepaper for more information. Open source: https://github.com/victronenergy/dbus_modbustcp
• dbus-systemcalc-py
  Written in Python, publish PV totals and other system readings on D-Bus. The overviews on the CCGX get their information from this service (com.victronenergy.system). Open source: https://github.com/victronenergy/dbus-systemcalc-py

As visible in above project list, part of the sources is already available. All that is open source is available on https://github.com/victronenergy/. The rest is still on Victrons internal git servers, and where possible slowly being moved to github.

• Have a local version of https://vrm.victronenergy.com including database run on the CCGX itself, using php/hiawatha and sqlite.
• Secure VNC (http://www.victronenergy.com/live/ccgx:ccgx_vnc), and make it useable remotely when the CCGX is behind a firewall.

Functionality wise, the plans are (in random order):

• Make support for more types of sensors (temp sensors etc)
• Be able to use BMV's to read current from for example a dc wind generator, and show on overview and VRM portal
• Make more of the project open source
• Further mature alarms, and add SMS and email notifications
• Make it usable as a UPS-replacement. local website, emailalerts, battery minutes remaining, etc.
• Add SNMP (UPS-MIB)

• to make a screenshot, first press and hold the down button, and then press the up button. The screenshot will be saved to /opt/color-control/gui/. It will overwrite the previous one.

And see color_control_gx for more CCGX development information
