+# Getting started building or modifying
+
+## Tools
+
+### Kicad
+
+Install the [KiCad](http://www.kicad-pcb.org/) program to edit the schematic or PCB.
+KiCad documentation and forums:
+
+* https://kicad-pcb.org/help/documentation/#_getting_started
+* https://forum.kicad.info/
+* https://www.reddit.com/r/KiCad/
+* https://en.wikipedia.org/wiki/KiCad
+
+### Simulator
+
+If you want to simulate parts of the circuit you also need a simulator. This is
+highly recommended! This saves a *lot* of troubleshooting and makes you find
+solutions you otherwise would not have found.
+
+[Electronic circuit simulation](https://en.wikipedia.org/wiki/Electronic_circuit_simulation)
+using computers have a long history. Many of them have origins directly or indirectly
+related to the classic SPICE simulator (e.g. [Ngspice](http://ngspice.sourceforge.net)).
+At the core they work similar to source code compilers - you give it a text file
+describing the circuit and it produces a textual simulation result. Some of the simulators
+are intended to be used just in text mode while other have a graphical frontend where
+you are able to draw the circuit like in a schematic editor:
+
+ * [QUCS](http://qucs.sourceforge.net/) - Quite Universal Circuit Simulator.
+ * [QUCS-S](https://ra3xdh.github.io/) - A qucs version using ngspice as simulation backend. This one has been used for the simulations for board 3.
+ * [eSim](http://esim.fossee.in/).
+ * [Other alternatives](https://en.wikipedia.org/wiki/List_of_free_electronics_circuit_simulators).
+
+### Git
+
+While it is possible to download the content from this repository as a compresset
+zip file, you want to use git to fetch the content. For Linux install depending on
+distribution with
+
+```
+apt-get install git   # debian, ubuntu, etc
+dnf install git       # fedora
+yum install git       # rhel, centos
+```
+
+For windows the most convenient option is to install [git for windows](https://git-scm.com/download/win).
+
+To download the source of this repository run:
+
+```
+git clone https://github.com/roarfred/AmsToMqttBridge
+cd AmsToMqttBridge
+git submodule init
+git submodule update --recursive
+```
+
+Make sure that all submodules are fetched. If not `git submodule status` will show something like the following (notice the `-` in front):
+
+```bash
+-f886cacb58461d356730e744d9d2ae55590825e4 kicad-symbols
+```
+
+while when properly fetched it will show the commit id normally
+(plus any labels if appropriate):
+
+```bash
+ f886cacb58461d356730e744d9d2ae55590825e4 kicad-symbols (5.0.0-rc1)
+```
+
+To mitigate, run update:
+
+```bash
+$ git submodule update --init
+Submodule 'Electrical/kicad-libs/kicad-symbols' (https://github.com/kicad/kicad-symbols) registered for path 'kicad-symbols'
+Cloning into '.../AmsToMqttBridge/Electrical/kicad-libs/kicad-symbols'...
+Submodule path 'kicad-symbols': checked out 'f886cacb58461d356730e744d9d2ae55590825e4'
+```

+# Electrical Design
+
+### **!!NOTE!!**
+The more mature version of a HAN Port reader is available under the folder [HAN_ESP_TSS721](../HAN_ESP_TSS721). The main difference in these two versions are that this one is using a proprietary (but simpler) circuit for the M-bus to TTL
+conversion and has very limited resources available for doing work on the schematics and PCB. The [HAN_ESP_TSS721](../HAN_ESP_TSS721) is using a TSS721 circuit
+from Texas Instruments, specifically designed for M-bus to TTL conversion. Also
+all design is available for you in a [KiCad](https://www.kicad-pcb.org) format.
+
+
+## Explained
+The design is using an opamp as a compined level converter and a schmitt trigger, in order to convert 
+the HAN signal into a 3.3V compatible serial format. As the input levels on the opamp is much higher 
+than our 5V supply, we are rectifying and smoothing the HAN signal to use for a supply here. (VDD)
+
+As a power source, we've used a micro USB connector, providing 5V, just as this is cheap and easy. However,
+no part of the circuit will need any other power than the 3.3V, so any combination of power source and 
+regulator that provides the 3.3V will do.
+
+The ESP8266 setup is a rather standaraized setup and will allow for programming the ESP directly on the 
+board, if needed. During programming, it might be neccessary to disconnect the incoming HAN.
+
+### **!!important changes!!**
+> * R8 should not be used
+> * The two unused inputs on the LM358 should be grounded (Pin 5 and 6)

+
+# Overview
+
+This represents an alernative PCB for interfacing the HAN M-bus connector
+on AMS meters.
+
+The biggest difference between this board and [the original board](../Board_001)
+is that this board supports communication over a physical wire.
+
+So you can for instance use this board together with an arduino to make
+a robust watt-meter display that will never fail because of connection
+issues (unlike wifi).
+
+This solution uses the industry standard chip for M-bus communication,
+[TSS721A](http://www.ti.com/lit/ds/symlink/tss721a.pdf) with full
+galvanic isolation to the bus, e.g. connecting a cable from this PCB
+to a mains connected PC for instance will not result in a [ground
+loop](https://en.wikipedia.org/wiki/Ground_loop_%28electricity%29).
+
+The schematic and drawings are made with
+[KiCad](http://www.kicad-pcb.org/).
+
+
+# Scope
+
+## Software
+
+Reuse existing [code](../../Code).
+
+## Hardware
+
+Only support receiving transmitted serial data from the bus since the
+Kamstrup AMS meters have no physical support for receiving anything.
+
+The primary use case is to be a shield on an Arduino board (e.g. Uno or
+Leonardo). A standalone ATtiny version would be nice to have as well.
+
+Support daisy-chaining multiple units on the bus.
+
+
+# Status
+
+This is unfinished work, currently just started.
+
+# Future
+
+First phase is only supporting converting M-Bus data to serial I/O.
+Support for ethernet or USB will be implicit via Arduino/shields. Later
+standalone versions with ATTiny will be most useful by including
+ethernet/usb support directly.
+
+## Step 1
+
+Create a simple M-Bus master simulator (transmit only) that takes
+serial data and modulates onto the bus. Write arduino code to send a
+test pattern and verify on oscilloscope.
+
+https://electronics.stackexchange.com/questions/99388/designing-a-m-bus-master-up-to-10-slaves/99390#99390
+https://electronics.stackexchange.com/a/214477/568
+
+## Step 2
+
+Connect the TSS721A chip with all required components with a optocoupler
+between it and Arduino (e.g. M-Bus to TTL conversion). Connect with the
+simulator from step 1 and verify that received data equals the data sendt.
+
+Possibly also test with off-the-shelf M-Bus to TTL conversion hardware
+for comparison.
+
+## Step 3
+
+Finish PCB design to be a usable Arduino shield. Integrate the
+AmsToMqttBridge software. Display received data on LCD.
+
+## Step 4
+
+Put code onto ATTiny on a standalone board with support for either USB
+or ethernet.
+
+The MCP2221 is an inexpensive<sup>1</sup> USB to serial chip that people
+[seems](https://www.element14.com/community/groups/open-source-hardware/blog/2016/02/01/implementing-non-ftdi-usb-to-uart-serial-interfaces)
+[very](http://www.eevblog.com/forum/reviews/alternatives-to-ftdi-usb-to-uart-converter/)
+[satisfied](https://hackaday.io/project/18845-usb-serial-uart)
+[with](https://hackaday.com/2016/03/04/dual-uarti2c-breakout-goes-both-ways/).
+It does [not](http://blog.zakkemble.co.uk/mcp2221-hid-library/)
+[achieve](https://hackaday.com/2017/05/31/counterfeit-hardware-may-lead-to-malware-and-failure/#comment-3636318)
+the maximum speeds is theoretically supports, but that is irrelevant for
+this project. This board should then be powered by USB, both in that that
+is the most natural and convinient choice and that if not then apparently
+MCP2221 needs some additional electronics in order to [work properly as
+an USB device](https://electronics.stackexchange.com/a/323551/568).
+
+For ethernet the
+[ENC28J60](http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en022889)
+chip seems to be the
+[go](https://www.reddit.com/r/arduino/comments/18pw59/diycheap_ethernet_shields/)

+DYI solutions. It only supports 10Mpbs, but that is more than
+good engough for pushing out MQTT messages. It draws a significant
+amount of current (~120mA or more) and gets gets hot so it might
+need heatsinking, but that is an [inherent problem with all ethernet
+controlles](https://electronics.stackexchange.com/questions/52349/why-is-ethernet-so-power-hungry).

+# Overview
+
+This board can be used to simulate a M-Bus master device instead of
+connecting to the real AMS unit, i.e. usable for test and development.
+It takes a 5 V TTL level input (serial) signal and converts it
+to a M-bus level signal. It supports both sending and receiving.
+Inspired by [MBus_USB.pdf](https://github.com/rscada/libmbus/blob/master/hardware/MBus_USB.pdf)<sup>1</sup>,
+although significantly improved by using zener diodes so that it is
+flexible and can work with any external power source between
+21 and 42 Volt. Most DC-DC boost/step-up converter
+modules<sup>2</sup> should be fine for this.
+
+![](MBus_Simulator.png?raw=true)
+
+## BOM
+
+* 1 x zener diode [13V](https://www.elfadistrelec.no/en/zener-diode-017aa-13-on-semiconductor-1n5350bg/p/17006687) (note below)
+* 1 x zener diode [4.7V](https://www.elfadistrelec.no/en/zener-diode-do-35-500-mw-vishay-bzx55c4v7/p/30030851)
+* 1 x [BD136 transistor](https://www.elfadistrelec.no/en/power-transistor-to-126-pnp-45-no-brand-bd136-16/p/17130046) (most pnp bjt will probably work (with 40+ operating voltage))
+* 4 x [BC337 transistor](https://www.elfadistrelec.no/en/transistor-to-92-npn-45-800-ma-diotec-bc337-25bk/p/30012857) (probably any npn bjt will do (with 40+ operating voltage)
+* 1 x resistor 82 ohm
+* 1 x resistor 1k
+* 1 x resistor 8.2k (you can use 10k if power supply is well above 21V)
+* 5 x resistor 10k
+* 1 x resistor 220k
+* 4 x pin header 1x2
+
+
+Note for the 13V zener. This board design depends on the zener to
+operate below 1mA, e.g. like 1N5350 (figure 8) whereas a BZX55
+(figure 9) will maybe not operate properly.
+
+![](zener_ok.png?raw=true) ![](zener_not_ok.png?raw=true)
+
+This limitation could be lifted by reducing the 8.2k resistor so that it
+draws enough current.

+This directory contains various simulation of the M-Bus part of [MBus_USB.pdf](../doc/MBus_USB.pdf?raw=true).
+The simulattions are done with [qucs-s](https://ra3xdh.github.io/) using [ngspice](http://ngspice.sourceforge.net)
+as simulation backend.
+
+The first simulation is as close to the original as possible and gradulally changed to
+remove receiving parts and using a zener diode to have a constant 12V voltage drop
+regardless of the power supply. The final version works with any voltage in M-Bus range.
