All of the boards share the same core pin functionality but call pins by
|
|
||||||
different names. The table below matches the pin order in
|
|
||||||
`the datasheet <http://ww1.microchip.com/downloads/en/DeviceDoc/40001882A.pdf>`_
|
|
||||||
and omits the pins only available on the largest package because all supported
|
|
||||||
boards use smaller version.

Here is a table about which pins can do what in CircuitPython terms. However,
|
|
||||||
just because something is listed, doesn't mean it will always work. Existing use
|
|
||||||
of other pins and functionality will impact your ability to use a pin for your
|
|
||||||
desired purpose. For example, only certain combinations of SPI pins will work
|
|
||||||
because they use shared hardware internally.

Setup
|
|
||||||
-----
|
|
||||||
|
|
||||||
An ARM compiler is required for the build, along with the associated binary
|
|
||||||
utilities. They can be installed as follows:
|
|
||||||
|
|
||||||
- Ubuntu
|
|
||||||
|
|
||||||
.. code-block:: shell
|
|
||||||
|
|
||||||
sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
|
|
||||||
sudo apt-get install gcc-arm-embedded
|
|
||||||
|
|
||||||
- Arch Linux
|
|
||||||
|
|
||||||
.. code-block:: shell
|
|
||||||
|
|
||||||
sudo pacman -S arm-none-eabi-gcc arm-none-eabi-newlib
|
|
||||||
|
|
||||||
For other systems, the `GNU Arm Embedded Toolchain <https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads>`_
|
|
||||||
may be available in binary form.
|
|
||||||
|
|
||||||
The latest available package from team-gcc-arm-embedded is used to produce the
|
|
||||||
binaries shipped by AdaFruit. Other compiler versions, particularly older
|
|
||||||
ones, may not work properly. In particular, the ``gcc-arm-none-eabi`` package
|
|
||||||
in Debian Stretch is too old.
|
|
||||||
|
|
||||||
The compiler can be changed using the ``CROSS_COMPILE`` variable when invoking
|
|
||||||
``make``.
|
|
||||||
|
|
||||||
Building
|
Building
|
||||||
--------
|
--------
|
||||||
|
|
||||||
Before building the firmware for a given board, there are two additional steps.
|
For build instructions see this guide: https://learn.adafruit.com/building-circuitpython/
|
||||||
These commands should be executed from the root directory of the repository
|
|
||||||
(``circuitpython/``).
|
|
||||||
|
|
||||||
1. There are various submodules that reside in different repositories. In order
|
|
||||||
to have these submodules locally, you must pull them into your clone, using:
|
|
||||||
|
|
||||||
.. code-block:: shell
|
|
||||||
|
|
||||||
git submodule update --init --recursive
|
|
||||||
|
|
||||||
2. The MicroPython cross-compiler must be built; it will be used to pre-compile
|
|
||||||
some of the built-in scripts to bytecode. The cross-compiler is built and
|
|
||||||
run on the host machine, using:
|
|
||||||
|
|
||||||
.. code-block:: shell
|
|
||||||
|
|
||||||
make -C mpy-cross
|
|
||||||
|
|
||||||
|
|
||||||
Build commands are run from the ``circuitpython/ports/atmel-samd`` directory.
|
Debugging
|
||||||
|
|
||||||
To build for a given board you must specify it by setting ``BOARD``. For example:
|
|
||||||
|
|
||||||
.. code-block:: shell
|
|
||||||
|
|
||||||
make BOARD=feather_m0_basic
|
|
||||||
|
|
||||||
Board names are the directory names in the `boards <https://github.com/adafruit/circuitpython/tree/master/ports/atmel-samd/boards>`_ folder.
|
|
||||||
|
|
||||||
Deploying
|
|
||||||
---------
|
---------
|
||||||
|
|
||||||
Arduino Bootloader
|
For debugging instructions see this guide: https://learn.adafruit.com/debugging-the-samd21-with-gdb
|
||||||
^^^^^^^^^^^^^^^^^^
|
|
||||||
|
|
||||||
If your board has an existing Arduino bootloader on it then you can use bossac
|
|
||||||
to flash MicroPython. First, activate the bootloader. On Adafruit Feathers you
|
|
||||||
can double click the reset button and the #13 will fade in and out. Finally,
|
|
||||||
run bossac:
|
|
||||||
|
|
||||||
tools/bossac_osx -e -w -v -b -R build-feather_m0_basic/firmware.bin
|
|
||||||
|
|
||||||
No Bootloader via GDB
|
|
||||||
^^^^^^^^^^^^^^^^^^^^^
|
|
||||||
|
|
||||||
This method works for loading MicroPython onto the Arduino Zero via the
|
|
||||||
programming port rather than the native USB port.
|
|
||||||
|
|
||||||
Note: These instructions are tested on Mac OSX and will vary for different
|
|
||||||
platforms.
|
|
||||||
|
|
||||||
openocd -f ~/Library/Arduino15/packages/arduino/hardware/samd/1.6.6/variants/arduino_zero/openocd_scripts/arduino_zero.cfg
|
|
||||||
|
|
||||||
In another terminal from ``micropython/atmel-samd``:
|
|
||||||
|
|
||||||
arm-none-eabi-gdb build-arduino_zero/firmware.elf
|
|
||||||
(gdb) tar ext :3333
|
|
||||||
...
|
|
||||||
(gdb) load
|
|
||||||
...
|
|
||||||
(gdb) monitor reset init
|
|
||||||
...
|
|
||||||
(gdb) continue
|
|
||||||
|
|
||||||
Connecting
|
|
||||||
----------
|
|
||||||
|
|
||||||
Serial
|
|
||||||
^^^^^^
|
|
||||||
|
|
||||||
All boards are currently configured to work over USB rather than UART. To
|
|
||||||
connect to it from OSX do something like this:
|
|
||||||
|
|
||||||
screen /dev/tty.usbmodem142422 115200
|
|
||||||
|
|
||||||
You may not see a prompt immediately because it doesn't know you connected. To
|
|
||||||
get one either hit enter to get `>>>` or do CTRL-B to get the full header.
|
|
||||||
|
|
||||||
Mass storage
|
|
||||||
^^^^^^^^^^^^
|
|
||||||
|
|
||||||
All boards will also show up as a mass storage device. Make sure to eject it
|
|
||||||
before resetting or disconnecting the board.
