John:

== Dependencies ==

You can use either windows or linux, although windows will not have most things installed by default

=== git, make, python, etc ===
I will just assume you have this

=== arm-none-eabi-gcc ===
https://launchpad.net/gcc-arm-embedded/+download
You will have to make the arm-none-eabi-gcc from the bin directory available to your system (add to PATH, symlink or copy)

On Ubuntu you can follow these instructions: https://launchpad.net/~team-gcc-arm-embedded/+archive/ubuntu/ppa

=== pyusb===
<pre>sudo pip install pyusb</pre>

== USB Permissioning on Linux ==

On some Linux distributions it may be necessary to add additional udev rules in order to allow the REPL to work:

copy the following text to /etc/udev/rules.d/49-tilda-mk3.rules

<pre>
# 0483:df11 - Tila Mk3 based on Mircropython board
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", ENV{MTP_NO_PROBE}="1"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE:="0666"
</pre>

And then restart the udev service:

<pre>
sudo udevadm control --reload-rules
</pre>

== Flashing ==

<pre>
# Clone this repo
git clone --recursive git@github.com:emfcamp/micropython.git

# Switch to our work branch
cd micropython
git checkout tilda-master

# Now we can build the firmware and flash it to the badge
# You have to boot the badge into dfu mode by pressing down the center
# joystick button while pressing the reset button to trigger a reboot
make -C stmhal BOARD=STM32L475_EMFBADGE deploy
</pre>
