-# ATTNode v3 Firmware
+# ATTNode v3 Firmware (WiP)

-This is the code repository for ATTNode v3 compatible firmware. At the moment it supports LoRa communication using OTAA and a growing number of sensor, like the BME280 and SHT21 for temperature, humidity and atmospheric pressure, MH-Z19C and SCD30 for CO2 or HM330x for Particulate Matter. It also uses deep sleep to save energy between Measurements.
+## Disclaimer

-The firmware is developed using [PlatformIO](https://platformio.org/). At least version 5.1.0 is needed for ATTiny3216 support.
+THIS IS STILL WORK IN PROGRESS!

 ## Documentation

 ## Configuration and Programming

-To set the fuses for clock speed, BOD levels etc., use the "Set Fuses" operation in PlatformIO. This has to be done once for a "fresh" Node or when the Board Config in platformio.ini was changed. Afterwards it is enough to use the normal "Upload" function for Code or config.h changes.
+This is the Work in Progress Repository for ATTNode v3 compatible firmware. At the moment it supports LoRa communication using OTAA and a BME280 or SHT21 sensor, as well as deep sleep between measurements.

-Before programming a node, copy src/config.h.example to src/config.h and set the used sensor, LoRaWAN keys and other options as needed.
+As there is no PlatformIO Support for the ATTiny3216 yet, it is (for now) developed using Arduino IDE and the [MegaTinyCore](https://github.com/SpenceKonde/megaTinyCore). You also need to set the correct Settings for programming the ATTiny3216 in ArduionIDE. Here is a screenshot of the settings I use:

-Programming is done using a [MicroUPDI Programmer](https://github.com/MCUdude/microUPDI), settings in platformio.ini are set to use it. For other pogrammer options see the PlatformIO Documentation
+![ArduinoIDE Settings](ide_settings.png)

-## Debugging
+You also need to install the MCCI Arduino LMIC Library form the IDEs Library Manager or from https://github.com/mcci-catena/arduino-lmic

-The firmware has the ability to produce some debug output via the Serial UART as long as there is no sensor using the UART. To enable it, uncomment the line -D DEBUG in platformio.ini. This will produce some debug output showing the state of the node. The following macros are available as a replacement for the normal Serial.print and Serial.println functions:
+Before Compiling and Flashing make sure to copy config.h.example to config.h and set your LoRa OTAA Keys there. You can also set the Sending Interval and used Sensors there.

-    DEBUG_PRINT("Debug Output");
-    DEBUG_PRINTLN("Debug Output with Linebreak");
-
-These will only produce additional code in the firmware when the DEBUG-Flag is enabled, and will be entirely removed in the ouput binary if not. The macros work like the normal Serial.print* statements form the standard arduino functions.
-
-## Payload Decoder
-
-You need to specify a Payload Decoder fitting for your configured Sensors for a Node. See payload/index.html in this repository. Open it in your Browser of Choice and select the enabled sensors. It will generate the Payload Decoder fitting for the choosen Sensors. You can also use the Online Version at [attno.de](https://www.attno.de/payload-generator)
+Programming is done using a [MicroUPDI Programmer](https://github.com/MCUdude/microUPDI) - for other pogramming variants see the MegaTinyCore documentation.

 ## Configuring via Downlink

-It is possible to change the sending interval via Downlink-Packets at runtime. Downlinks for setting the transmit interval have to be sent on port 1. The time between Transmits is specified in minutes (or more exactly, 64 Second intervals) and as a 2 byte value, which will be interpreted as an uint. So for example 0x0001 means 1 Minute, 0x0002 means 2 Minutes and so on. Sending 0xFFFF resets the value to the compiled in default.
-
-Sending an arbitrary value on port 2 will activate the calibration sequence for sensors that support it (like some of the CO2-Sensors).

-This directory is intended for project header files.
-
-A header file is a file containing C declarations and macro definitions
-to be shared between several project source files. You request the use of a
-header file in your project source file (C, C++, etc) located in `src` folder
-by including it, with the C preprocessing directive `#include'.
-
-```src/main.c
-
-#include "header.h"
-
-int main (void)
-{
- ...
-}
-```
-
-Including a header file produces the same results as copying the header file
-into each source file that needs it. Such copying would be time-consuming
-and error-prone. With a header file, the related declarations appear
-in only one place. If they need to be changed, they can be changed in one
-place, and programs that include the header file will automatically use the
-new version when next recompiled. The header file eliminates the labor of
-finding and changing all the copies as well as the risk that a failure to
-find one copy will result in inconsistencies within a program.
-
-In C, the usual convention is to give header files names that end with `.h'.
-It is most portable to use only letters, digits, dashes, and underscores in
-header file names, and at most one dot.

-Copyright (c) 2007, Jim Studt  (original old version - many contributors since)
-
-The latest version of this library may be found at:
-  http://www.pjrc.com/teensy/td_libs_OneWire.html
-
-OneWire has been maintained by Paul Stoffregen (paul@pjrc.com) since
-January 2010.
-
-DO NOT EMAIL for technical support, especially not for ESP chips!
-All project support questions must be posted on public forums
-relevant to the board or chips used.  If using Arduino, post on
-Arduino's forum.  If using ESP, post on the ESP community forums.
-There is ABSOLUTELY NO TECH SUPPORT BY PRIVATE EMAIL!
-
-Github's issue tracker for OneWire should be used only to report
-specific bugs.  DO NOT request project support via Github.  All
-project and tech support questions must be posted on forums, not
-github issues.  If you experience a problem and you are not
-absolutely sure it's an issue with the library, ask on a forum
-first.  Only use github to report issues after experts have
-confirmed the issue is with OneWire rather than your project.
-
-Back in 2010, OneWire was in need of many bug fixes, but had
-been abandoned the original author (Jim Studt).  None of the known
-contributors were interested in maintaining OneWire.  Paul typically
-works on OneWire every 6 to 12 months.  Patches usually wait that
-long.  If anyone is interested in more actively maintaining OneWire,
-please contact Paul (this is pretty much the only reason to use
-private email about OneWire).
-
-OneWire is now very mature code.  No changes other than adding
-definitions for newer hardware support are anticipated.
-
-Version 2.3:
-  Unknown chip fallback mode, Roger Clark
-  Teensy-LC compatibility, Paul Stoffregen
-  Search bug fix, Love Nystrom
-
-Version 2.2:
-  Teensy 3.0 compatibility, Paul Stoffregen, paul@pjrc.com
-  Arduino Due compatibility, http://arduino.cc/forum/index.php?topic=141030
-  Fix DS18B20 example negative temperature
-  Fix DS18B20 example's low res modes, Ken Butcher
-  Improve reset timing, Mark Tillotson
-  Add const qualifiers, Bertrik Sikken
-  Add initial value input to crc16, Bertrik Sikken
-  Add target_search() function, Scott Roberts
-
-Version 2.1:
-  Arduino 1.0 compatibility, Paul Stoffregen
-  Improve temperature example, Paul Stoffregen
-  DS250x_PROM example, Guillermo Lovato
-  PIC32 (chipKit) compatibility, Jason Dangel, dangel.jason AT gmail.com
-  Improvements from Glenn Trewitt:
-  - crc16() now works
-  - check_crc16() does all of calculation/checking work.
-  - Added read_bytes() and write_bytes(), to reduce tedious loops.
-  - Added ds2408 example.
-  Delete very old, out-of-date readme file (info is here)
-
-Version 2.0: Modifications by Paul Stoffregen, January 2010:
-http://www.pjrc.com/teensy/td_libs_OneWire.html
-  Search fix from Robin James
-    http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
-  Use direct optimized I/O in all cases
-  Disable interrupts during timing critical sections
-    (this solves many random communication errors)
-  Disable interrupts during read-modify-write I/O
-  Reduce RAM consumption by eliminating unnecessary
-    variables and trimming many to 8 bits
-  Optimize both crc8 - table version moved to flash
-
-Modified to work with larger numbers of devices - avoids loop.
-Tested in Arduino 11 alpha with 12 sensors.
-26 Sept 2008 -- Robin James
-http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1238032295/27#27
-
-Updated to work with arduino-0008 and to include skip() as of
-2007/07/06. --RJL20
-
-Modified to calculate the 8-bit CRC directly, avoiding the need for
-the 256-byte lookup table to be loaded in RAM.  Tested in arduino-0010
-- Tom Pollard, Jan 23, 2008

-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.
