-ParaTNC wersja 1.0-19082017
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-// W katalogu 'doc' znajduje się większa ilość dokumentacji i instrukcji użytkownika
-// obecnie ten plik jest przestarzay i nie obejmuje najnowszych możliwości oprogramowania i sprzętu
-// ParaTNC. Proszę przeczytać anglojęzyczną wersję w pliku README 
-
-1. WSTĘP
-ParaTNC jest oprogramowaniem wbudowanym (firmware) przeznaczonym do pracy na płytce STM32VLDISCOVERY w charakterze
-uniwersalnego radiomodemu/sterownika sieci APRS, wyposażonego w szereg funkcjonalności takich jak:
-
--> Digipeater retransmitujący pakiety posiadające ustawioną ścieżkę WIDE1-1.
--> Dwustronna komunikacja z komputerem przy użyciu protokołu KISS po łączu szeregowym (TTL-UART).
--> Stacja pogodowa z obsługą wiatromierza TX20, termometru Dallas DS12B20 oraz czujnika ciśnienia MS5611.
--> Telemetria umożliwiająca monitorowanie ilości odbieranych, nadawanych i powtarzanych pakietów.
--> Obsługa protokołu tekstowego VE.Direct używanego przez systemu fotowoltaiki Victron Energy
-
-Niewątpliwą zaletą ParaTNC są bardzo niskie koszta. Wynoszące jedynie 60~70pln bruttno na zakup STM32VLDISCOVERY. 
-Ponieważ dekodowanie i generowanie transmisji APRS odbywa się w pełni programowo nie ma konieczności użycia tandetnych
-podróbek modemu TCM, sprzedawanych obecnie na ebay i aliexpress przez dostawców z Chin. Lutowanie ogranicza się wyłącznie
-do wykonania odpowienich kabli połączeniowch. stosowna instrukcja z pinoutami znajduje się w pliku WIRING.
-
-
-
-2. LICENCJA
-Warunki licencjonowania są zawarte w pliku LICENSE.   
-
-3. WSPIERANE FUNKCJONALNOŚCI PROTOKOŁU VE.DIRECT
-Protokół (w wersji tekstowej, nie binarnej) VE.Direct został stworzony przez firme Victron Energy i jest wykorzystywany
-w produkowanych przez nią inwerterów, kontrolerów ładowania i innego sprzętu do instalacji fotowoltaicznych. Służy on do
-przesyłania telemetrii z kontrolera do komputera PC, lub w tym przypadku sterownika ParaTNC. Jest on domyślnie włączony
-w większości urządzeń i w trybie bezczynności, tj. bez komunikacji protokołem binarnym z aplikacją konfiguracyjną 
-urządzenie będzie wysyłało co kilka sekund paczkę danych telemetrycznych.
-
-Komunikacja z urządzeniami Victron Energy odbywa się przez złącze VE.Direct, które jest tak naprawdę zwykłym złączem szeregowym.
-W przypadku regulatorów z serii MPPT (w moim przypadku model MPPT75/15) używane są sygnały na poziome TTL-3.3V, dlatego można
-je podłączyć do sterownika ParaTNC/STM32VLDISCOVERY bezpośrednio, tj. bez użycia konwerterów typu MAX232.
-
-Złącze VE.Direct w regulatorach z serii MPPT znajduje się poniżej bezpiecznika. Patrząc na złącze mając otwory montażowe w obudowie
-zwrócone ku dołowi rozpiska jest taka (od prawej do lewej)
-	-> Masa
-	-> TX, dane z regulatora do hosta (kontrolera)
-	-> RX, dane z hosta do regulatora. Nie wykorzystywany przez protokół tekstowy
-
-VE.Direct wysyła bardzo wiele różnych parametrów i informacji statusowych. Oczywiście ze względu na ograniczenia standardu APRS
-nie ma możliwości wysyłania wszystkiego, dlatego ostatecznie dokonano następującego wyboru
-
-   a) Prąd akumulatora (ładowanie/rozładowywanie), jako trzeci kanał telemetrii
-   b) Napięcie akulatora, jako czwarty kanał telemetrii
-   c) Napięcie fotoogniwa, jako piąty kanał telemetrii
-   d) Status urządzenia (aktualny tryby ładowania, brak ładowania, akumulator bliski rozładowania), jako część statusu
-   e) Kody błędów (zwarcie, zbyt wysokie napięcie aku/panela, przegrzanie, przeciążenie itp), jako część statusu  
-
-
-3. KONFIGURACJA
-Na chwilę obecną ParaTNC jest dostarczane w formie kodów źródłowych do samodzielnej kompilacji. Ponieważ dostępne jest 
-source, konfiguracja odbywa się przez edycję pliku ./include/station_config.h . Zawiera on komentarze tłumaczące znaczenie 
-poszczególnych opcji. Oprócz typowych i raczej trywialnych ustawień APRS takich jak znak wywoławczy i temu podobne,
-użytkownik może włączać i wyłączać poszczególne tryby pracy urządzenia. Możliwe są następujące kombinacje
-
--> KISS
--> KISS + DIGI
--> KISS + DIGI + METEO
--> VICTRON + DIGI + METEO
--> VICTRON + DIGI
-
-Włączenie funkcjonalności stacji pogodowej (przez odkomentowanie _METEO) automatycznie włącza digipeater nawet jeżeli
-zakomentowane jest #define _DIGI w pliku konfiguracyjnym. Komunikacja z komputerem odbywa się na prędkości 9600bps, a sam
-protokół KISS działa od samego początku pracy urządzenia i nie musi być w żaden sposób inicjalizowany ze strony PC.
-
-Włączenie wsparcia dla protokołu VE.Direct odbywa się przez odkomentowanie //#define _VICTRON. 
-UWAGA!! Włączenie VE.Direct wyłącza i uniemożliwia wykorzystanie ParaTNC w trybie modemu KISS. 
-
-Sterownik wysyła co 10 minut ramkę telemetryczną zawierającą informację o ilości odebranych, nadanych i powtórzonych
-pakietów APRS przez okres minionych 10 minut. Ilość nadanych ramek jest sumą powtórzonych ramek i ramek własnych 
-wliczając w to ramki telemetrii. Co ok 75 minut nadawane są pełne opisy kanałów.
-
-Sterownik nie umożliwia bezpośrednie transmitowanie jakichkolwiek danych do internetu (do serwerów APRS-IS) z powodów 
-oczywistych. Uruchomienie funkcjonalności igate wymaga podłączenia przez UART komputera PC, Raspberry-PI lub czegokolwiek
-innego na czym można uruchomić oprogramowanie takie jak APRX, APRSIS32, czy UiView32. Na chwile obecną pakiety własne,
-czyli generowane przez sterownik ramki pozycyjne, pogodowe czy telemetryczne są nadawane wyłącznie na port radiowy.
-W przyszłości pojawi się funkcjonalność polegająca na wysyłaniu przez KISS do komputera nie tylko ramek odebranych drogą
-radiową, ale również tych pochodzenia własnego.
-
-
-
-4. KOMPILACJA
-Do kompilacji oprogramowania ParaTNC na płytkę STM32VLDISCOVERY potrzebny jest zestaw narzędzi GNU ARM Embedded Toolchain 
-w którego skład wchodzi kompilator gcc-arm-none-eabi, debugger gdb, linker, oraz zestaw bibliotek i plików include.
-Dodatkowo niezbędny jest make i binutils znajdujący się w kazdej dystrybucji linuksa. ParaTNC został napisany i jest
-rozwijany na systemie Xubuntu 16.04LTS z toolchainem w wersji 2016q-3, aczkolwiek bez problemu będzie się kompilował na 
-dowolnie nowszej wersji. Kompilacja w systemie Windows czy MacOS nie jest wspierana ale powinna się udać, jeżeli ktoś
-potrafi odpowiednio skonfigurować całe środowisko.
- 
-W przypadku systemów Debian i ubunto-podobnych zdecydowanie zaleca się instalację toolchain przez aptitude z repozytorium
-internetowego. Jest to szybkie, wygodne i powoduje, że wszystkie komponenty są kopiowane do domyślnych folderów instalacji,
-co pozwala uniknąć serii błędów ze względu na niemożność odnalezienia ścieżki do np. gcc przez make.
-
-Informację na temat GNU ARM Embedded Toolchain, jego źródła, skompilowane wersję dystrybucyjne i dokumentację znajdują się:
-https://launchpad.net/gcc-arm-embedded
-https://developer.arm.com/open-source/gnu-toolchain/gnu-rm
-Instrukcja konfiguracji repo i instalacji pakietu znajduje się tutaj.
-https://launchpad.net/~team-gcc-arm-embedded/+archive/ubuntu/ppa
-
-Binutils i make znajduje się w repozytorium debiana/ubuntu, w przypadku GNU ARM Embedded należy zgodnie z instrukcją z
-powyższego linku dodać odpowiednie repozytorium zewnętrzne.
-
- 'sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa'
- 'sudo aptiude update'
- 'sudo aptitude install make automake binutils gcc-arm-embedded' 
-
-Jeżeli źródła nie zostały jeszcze skonfigurowane należy zainstalować w systemie git i sklonować repozytorium kodu
-na lokalny dysk twardy. W tym celu należy wydać polecenie będąc w katalogu gdzie chcemu aby znalazły się źródła:
-
- 'git clone https://github.com/sp8ebc/para-tnc' 
- 
-a następnie skonfigurować plik ./include/station_config.h . Po instalacji wymaganego programowania należy wejść w podkatalog 
-Debug i wydać polecenie 
-
- 'make'. 
-
-Źródła powinny się skompilować a w tymże katalogu pojawić się plik 'ParaTNC-ARM-Lite.hex' gotowy do wgrania do płytki.
-Dowodem na poprawne zakończenie procesu są poniższe komunikaty w konsoli, które powinny pojawić się pod sam koniec procesu
-kompilacji

-5. WGRYWANIE PLIKU HEX DO PŁYTKI STM32VLDISCOVERY
-Płytka STM32VLDISCOERY ma wbudowany programator/debugger sprzętowy ST-Link v1. Komunikacja z nim odbywa się przez 
-komendy SCSI passthrough a samo urządzenie wykrywa się w systemie jako pamięć masowa. W domyślnej konfiguracji po 
-podłączeniu płytki prez USB do komputera system (a dokładnie modprobe) automatycznie załaduje dla tego urządzenia sterownik
-mass-storage, system zamontuje emulowany przez programator system plików jako pendrive, co uniemożiwi zaprogramowanie. 
-W związku z powyższym należy w jego konfiguracji zablokować takie zachowanie. Robi się to przy pomocy polecenia:
-
- 'sudo echo "options usb-storage quirks=483:3744:i" >> /etc/modprobe.d/stlink_v1.conf'
- 
-Po ponownym uruchomieniu komputera warto sprawdzić, czy konfiguracja działa. Po podłączeniu STM32VLDISCOERY żadna dodatkowa
-pamięć masowa (pendrive) nie powinna zostać zamontowana. Po sprawdzeniu przez 'dmesg' na końcu powinno być miej więcej coś 
-takiego:
-
-[90639.895886] usb 2-1.1: new full-speed USB device number 13 using ehci-pci
-[90639.990288] usb 2-1.1: New USB device found, idVendor=0483, idProduct=3744
-[90639.990294] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
-[90639.990296] usb 2-1.1: Product: STM32 STLink
-[90639.990298] usb 2-1.1: Manufacturer: STMicroelectronics
-[90639.990300] usb 2-1.1: SerialNumber: QÿrI\xffffffc2\xffffff86RV%X\xffffffc2\xffffff87
-[90639.990796] usb-storage 2-1.1:1.0: USB Mass Storage device detected
-[90639.992973] usb-storage 2-1.1:1.0: device ignored
-
-W dalszym ciągu należy zainstalować oprogramowanie texane-stlink które służy do obsługi programatora stlink-v1/v2 w 
-systemie linux. 
-
-  'git clone git://github.com/texane/stlink.git'
-  'cd stlink.git'
-  'make'
-  'cd build/Relase'
-  'sudo cp st-* /usr/bin'
-  
- Na koniec, jeżeli programator działa można wrzucić program do płytki. Po przejściu do katalogu ./para-tnc/Debug
- wywołuje się następujące polecenie
- 
-  'sudo st-flash --format ihex write /dev/sr0 ParaTNC-ARM-lite.hex'
- 
- Jeżeli podczas programowania w konsoli wyskoczy błąd -1, lub jakikolwiek inny warto zresetować płytkę przez wyjęcie
- i ponowne włożenie wtyczki USB (czarny przycisk RST jest podłączony do targetu a nie programatora).

-ParaTNC version DF15, April 4th 2021
------------------------------------------
+# ParaTNC and ParaMETEO firmware version EA19, April 2023
 
 // Please look into 'doc' directory for more documentation and user manuals
 // WARNING: This readme could be sligtly outdated due to my lack of time :)
 
-// Ongoing changes
-// ---------------
-// Currently intense refactoring is done, which will result in new main software version EA00.
-// EA00 will remove the support for any Hardware Revision before HW-RevC, so it won't work on STM32VLDISCOVERY
-// anymore. Conditional compilation will be removed, so EA00 and all consecutive version will be build as 
-// one binary with support to everything. The configuration will be kept in Flash memory and could be 
-// altered 'on the fly' by using some external (not yet started) software tool, without a need to recompile
-// and reflash the controller. 
+#### INTRODUCTION 
 
-1. INTRODUCTION
-ParaTNC is a hardware and a software which offers the functionality of multi function APRS controler. 
-The software itself can also run on cheap STM32VLDISCOVERY board with slightly reduced functionality, but
-with costs about 10..12 euro this gives the cheapest possible standalone APRS controller.
+ParaTNC and ParaMETEO is a two APRS controller which has sligtly different target and different features. Source code in this repository called ParaTNC is a firmware to both of them. The name comes from the fact that ParaTNC was the first project. 
  
-ParaAPRS supports key elements of what good APRS device should have:
-   -> Two directional KISS TNC (no init strings required).
-   -> WIDE1-1 digipeater, with an option to limit digipeating only to SSIDs 7, 8 and 9.
-   -> Weather station with support for various meteo sensors. Full list od supported devices in point 5.
-   -> Extensive telemetry with an information about the count of receved, transmitted and digipeated frames plus status of weather sensors.
-   -> Support for VE.Direct serial protocol used in Victron PV charging controllers. The data about currents and voltages in the PV system are transmitted using APRS telemetry.
-   -> Support for UMB Binary porotocol as a mater.
+__ParaTNC__   supports key elements of what good APRS device should have:
+   - Two directional KISS TNC (no init strings required).
+   - WIDE1-1 digipeater, with an option to limit digipeating only to SSIDs 7, 8 and 9.
+   - Weather station with support for various meteo sensors. Full list od supported devices in point section below.
+   - Extensive telemetry with an information about the count of receved, transmitted and digipeated frames plus status of weather sensors.
+   - Support for VE.Direct serial protocol used in Victron PV charging controllers. The data about currents and voltages in the PV system are transmitted using APRS telemetry.
+   - Support for UMB Binary porotocol as a mater.
+   - Support for Modbus RTU
+   - Three different grounds separated one from the another (Controller, weather sensors, analog interface to FM radio)
 
-ParaAPRS can be used as a standalone weather station controller w/o using the radio transmission. The sw
-by default sends the measuremenets values 
+__ParaMETEO__   is full outdoor and easy to install, complete APRS device which can be supplied with power either from mains and PV system.. It supports the same list of feature than ParaTNC and:
+   - integrated MPPT charger for 12V / 9Ah AGM battery enclosed in the same case. 
+   - integrated GSM module and support for APRS-IS communication (can run RX-igate)
+   - support for MAX31865 amplifier for 2, 3 or 4-wire PT100/PT1000 temperature sensor
+   - 7.5V dc converter to supply HT radio installed in the case for APRS radio network
 
-2. ParaAPRS HARDWARE
-The ParaTNC software can run on STM32VLDISCOVERY board but it really shows it full potential od it's own
-dedicated hardware. This not only rub out all bodge wires required with prototype board. It gives 
-few features which are hardly not possible without dedicated PCB
- a) Two different grounds separated one from the another (HW Revision A and B)
- 	-> Controller
- 	-> DB9 connector used to interface with a radio and Wind & Temperature sensor
- aa) ONLY IN HW REVISION C: Three different grounds separated one from the another
- 	-> Controller
- 	-> DB9 connector used to interface with a radio
- 	-> Wind and temperature sensor including RS485 bus
- b) Isolated DC-DC coverter to supply sensors with an option to connect another external power supply itself
- c) A relay used as a watchdog to reset wind & temperature sensor in case that no communication will be received.
- d) RS232 serial port avaliable on Cisco style RJ45 connector.
- e) RS485 serial port interchable with RS232 (with HW Revision A) or working fully independly (HW Revision B)
- f) PCB designed to fit into Mikrotik RB411/RB711 enclosure.
- 
-ParaTNC PCB could be manufactured used a set of generber files locates in ./hardware/ directory a long with schematics and 
-layout renders (top and bottom layer).
- 
-3. CURRENT OPEN POINTS AND ISSUES RELATED TO HW & SW
-As usually every design has some flaws, less or more important. In case of ParaTNC they can be divided into two
-parts, separately for software and hardware. Firstly in case of software an end user should USE ALWAYS THE SOURCE CODE
-WITH THE NEWEST TAG marked as non-beta (like DE07). ParaTNC repository is used for daily development, so the last commit
-can even sometimes don't compile at all, or consist some major bugs. 
+***Please remember than ParaTNC firmware no longer runs on STM32VLDSICOVERY board!***
 
-Hardware workarounds in HW Revision A:
--> Missing resistor in series with base of transistor T2. External 1k must be added in series with TX line
--> Foortprint location of R7 (RX_LVL) and R8 (TX_LVL) helipots are 'not optimal'. If 'normal' pots are to be used the vertical
-   version must be chosen as flat one won't fit due to neighbouring components location. 
--> J1 power-in jack has reversed polarity (negative center)
--> The chineese manufacturer dropped the TX20 anemometer from the production which means that a supoprt to it
-   became a little bit obsoloete for new installations. Support for Davis 6410 anemometer or any another with
-   pulse output for windspeed and potentiometer (resistance output) for direction is ongoing and should be 
-   avaliable in HW-Revision B and further SW releases.
+ParaTNC PCB could be manufactured used a set of generber files locates in ./hardware/ directory a long with schematics and layout renders (top and bottom layer). 
 
-Hardware workarounds in HW Revision B:
--> Few missing traces in micro supply. Few bodge wired needs to be added. Please look at hardware-revision-b-errata.jpg in 'hardware'

 Most of Victron devices have a support both for binary and text serial protocol. By default the text procol (VE.Direct) is 
 always enabled and a device will send from its own telegrams each couple of seconds. The communication via VE.Direct is

 The controller sends a lot of different data which cannot be completely transmitted through APRS network due to radioprotocol 
 limitations. Only these parameters are transmitted:

- -> Battery Voltage as fourth telemetry channel.
- -> PV cell Voltage as fifth telemetry channel.
- -> Charging Controller status (like current charging mode) and minimum/maximum battery current in last 10 minutes.

-7. TELEMETRY
+*** Please note that VE.Direct is supported only in ParaTNC. In theory it is possible to connect any Victron Energy controller to ParaMETEO, but it has no sense in practice. ParaMETEO has it's own integrated chaging controller. ***
+
+#### TELEMETRY
 If the VE.Direct protocol suppot is disabled the ParaTNC uses telemetry packets to send internal statistics and
 general information about communication with sensors. Telemetry works in 10 minutes cycle, which means that packets are sent
 every 10 minutes and they represents a state for the time between one and another. 
 
-Analog channels:
-1st Channel: Number of packets received in 10 minutes.
-2nd Channel: Number of packets transmitted in 10 minutes (digi-ed + generated internally by the controller)
-3rd Channel: Number of digipeated packets in 10 minutes.
-4th Channel: Number of packet received from Host by KISS protocol
-5th Channel: Optional temperature from Dalls One Wire sensor.
+Analog channels (ParaTNC):
 
-Digital Channels:
-DS_QF_FULL	- Quality Factor for One Wire temperature sensor is FULL
-DS_QF_DEGRAD	- Quality Factor for One Wire temperature sensor is DEGRADATED
-DS_QF_NAVBLE	- Quality Factor for One Wire temperature sensor is NOT AVALIABLE
-MS_QF_NAVBLE	- Quality Factor for MS5611 pressure sensor ins NOT AVALIABLE
-DHT_QF_NAVBLE	- Quality Factor for DHT22 humidity & temperature is NOT AVALIABLE
-WIND_QF_DEGR	- LaCrosse TX20 anemometer driver dropped at least one measuremenet due to excesive slew rate.

 DEGRADATED is set if at least once the communication problem happened (CRC calculation fail, timeout etc). NOT AVALIABLE is set
 if all communication atempts failed and no valid measuremenet value is avaliable. By default each Quality Factor is set to 
 NOT AVALIABLE after the telemetry packets are sent.  
 
-The TX20 anemometer driver has a Slew Rate Limiter which keeps out all 'spikes' in values mostly due to RF interference. if the
-difference between two consecutive measuremenets excedes hardcoded limit (9m/s) the software drops the value.
