    Arduino board hardware notes - includes info on PWM pin mapping via jumpers and shows all pin functions

    'configure_edison' is the tool to setup wifi

    Notes:

    • Durring install "phone flash tool" says to unplug the board, make sure you plug it back in before clicking finish on that step
    • installer will upgrade the OS image and wipe out everything.  becareful, and keep backups!
    • for Arduino support, install the latest official IDE and use the board manager to make sure Edison support is installed.  use the usb port closer to the switch (you can also power the edison from this port)
    • In any Arduino code, inclduing libraries, bit shifting uint8_t into int will not do what you want, switch definition to short to restore expected behavior
    • known bug in latest Yocto causes sketches to stop running when you unplug the USB cable, and also does not persist on reboot.

    I2C - if cannot find Wire.h, copy wire.h and wire.cpp from the libraries/Wire/src/ folder to core/arduino folder. For me this was in C:\Users\%USERNAME%\AppData\Roaming\Arduino15\packages\Intel\hardware\i686\1.6.2+1.0\

    Grove 3 Axis Digital Compass -  use the github version, the official site and wiki are out of date.

     

    to enable the arduino i2c bus, i2c6, for linux use:

    echo 28 > /sys/class/gpio/export
    echo 27 > /sys/class/gpio/export
    echo 204 > /sys/class/gpio/export
    echo 205 > /sys/class/gpio/export
    echo 236 > /sys/class/gpio/export
    echo 237 > /sys/class/gpio/export
    echo 14 > /sys/class/gpio/export
    echo 165 > /sys/class/gpio/export
    echo 212 > /sys/class/gpio/export
    echo 213 > /sys/class/gpio/export
    echo 214 > /sys/class/gpio/export
    echo low > /sys/class/gpio/gpio214/direction
    echo low > /sys/class/gpio/gpio204/direction
    echo low > /sys/class/gpio/gpio205/direction

    echo in > /sys/class/gpio/gpio213/direction
    echo mode1 > /sys/kernel/debug/gpio_debug/gpio28/current_pinmux
    echo mode1 > /sys/kernel/debug/gpio_debug/gpio27/current_pinmux
    echo high > /sys/class/gpio/gpio214/direction
     
    i2cdetect -y -r 6
     
    Flash new firmware to the Grove motor driver on windows via an Arduino as ISP, adjust paths as needed.  Mac and Linux commands should be similar: 
    "C:\Program Files (x86)\Arduino\hardware\tools\avr\bin\avrdude.exe" -C"C:\Program Files (x86)\Arduino\hardware\tools\avr\etc\avrdude.conf" -patmega8 -carduino -P\\.\COM3 -b19200 Uflash:w:"C:\Users\chrisw\Downloads\Edison\Firmware for I2C motor Driver using ISP\motor driver firmware\mega8motor.hex":i
