The Android libraries used by this apps are not public and they can be purchase just contact us for more details.

  • GPIO handler:
    • the GPIO handler application is included to test the GPIO functionality. As example, it is possible to configure the GPIO 4 on the connector j7 on the Nitrogen6 Max. This GPIO is enumered as 9 in the GPIO handler application (generally the user space GPIO enumeration is handled by the Android/Linux Kernel)
  • CAN handler:
    • the CAN test application is included to test the CAN funcionality. A CAN bus is available on the J22 connection. The CAN bus can be configured via adb:
      • adb shell setprop persist.vendor.sys.can0.bitrate 115200
      • adb shell setprop persist.vendor.sys.can0.txqueuelen 5000
      • adb shell setprop persist.vendor.sys.can0.update_cfg 1
    • The last command is used to trigger the CAN configuration from ADB.
  • TTY Serial handler:
    • the TTY test application is included. It is possible to read and write on the serial RS232 available as /dev/ttymxcX. As example, the ttymxc0 RS232 serial is available on the J17 connector using the serial adapter from Boundary.
  • Ethernet handler
    • The Ethernet handler application allows to configure the ethernet interface (DHCP or static) from an Android application. In particular, the Ethernet handler application is developed in Xamarin: source code is available on github.
