3Devo platform and board files for Arduino

These files allow using the Devoboard in the Arduino IDE, allowing access to all pins on the board. To install, make a clone if this repository into your Sketchbook/hardware folder (so you would have Sketchbook/hardware/3devo/avr/platform.txt, for example).

Udev rules for USB device access (Linux)

To allow accessing USB devices, udev rules are needed to hand out access to normal users (resist the temptation to just run under sudo, since that might end up creating root-owned files everywhere and prevent running as non-root later or cause other issues).

For most devices, such rules are installed along with software (e.g. apt install dfu-util avrdude openocd gives you most relevant rules), but our own boards have custom USB identifiers unknown to these tools, so this needs a custom rule file.

To install it, do something like:

sudo cp ./udev-rules/3devo-devices.rules /etc/udev/rules.d

These rules should take effect directly when replugging the device, no restart or reload required.

In addition, some devices hand out access to the plugdev or dialout groups, so it is useful to add your own user to those groups:

sudo adduser yourusername dialout plugdev

This applies to Linux, under Windows permissions to USB devices are probably handed by default.
