-\section{Communication Specification}
-
-For the physical layer, RS-485 is used. This allows the communication to be robust and resistant to EMI (electro-magnetic interference). On top of the physical layer, Modbus RTU is used as a data link layer. This protocol is widely supported by the number of PLCs and other devices. To interface with a PC (or any computer with a USB port), a USB to RS485 converter may be used in conjunction with the Veles Sensors python library.
-
-\subsection{Physical Layer - RS485}
-
-RS-485 is a full-duplex serial bus, ideally suited for low-speed, noise-resistant communication over long distances (up to 1200 m - more if repeaters are used). Linear bus topology is preferable over star or ring configurations. To prevent signal reflections, each sensor is equipped with a 120 $\Omega$ termination resistor. Therefore, the optimal cable for connecting sensors to each other and to the master node is a twisted pair cable with 120 $\Omega$ characteristic impedance.
-
-\subsection{Data Link Layer - Modbus RTU}
-
-Modbus is a well-tested, openly-published, and royalty-free data communications protocol. Developed for industrial applications, it aims to be simple and robust. It is a client/server (master/slave) type protocol. The maximum number of client nodes on a Modbus bus is 247.
-
-A limitation of Modbus-based buses is that there is no arbitration in case of address conflict. This means that nodes should be either added one by one or node addresses should be configured beforehand.
-
-Address 0 can be used as a broadcast message (e.g. instructing all sensors to turn off LED). No slave response is generated.
-
-\subsubsection{Modbus register space}
-
-Modbus supports four types of registers:
-

-		\label{tab:modbus_holding_registers}
-\end{table}
-
-\paragraph{Note 1}
-\label{holdingReg:note1}
-Setting LED smooth register to 1 will turn on LED color interpolation, meaning the LED will have color in a continuous spectrum from green to red according to the $\mathrm{CO_2}$ level. Setting this register to 0 will turn off interpolation and set the LED to semaphore (tri-state) mode. Depending on $\mathrm{CO_2}$ level, the LED color will then be either green, yellow, or red.
-
-\paragraph{Note 2}
-\label{holdingReg:note2}
-Registers $\mathrm{CO_2}$ alert the limit 1 and 2 set thresholds for LED color change (see \hyperref[holdingReg:note1]{Note 1}). Limit 1 is the threshold between green and yellow color; limit 2 is the threshold between yellow and red color.
-
-\paragraph{Note 3}
-\label{holdingReg:note3}
-SCD41 is the $\mathrm{CO_2}$ sensing device used in the \sensor{} sensor. It is also able to measure temperature, however it may be subject to offset due to internal heating of SCD41. This register allows the user to compensate for this offset.
-
-\paragraph{Note 4}
-\label{holdingReg:note4}
-Device Modbus address may be changed by writing to this register. The allowed values are in the range of 1 to 247. The device will start using a new address immediately and cease to respond at the previous address. Reset is not needed. It is the responsibility of the user to prevent address collisions on a bus.
-
-\paragraph{Note 5}
-\label{holdingReg:note5}
-Modbus baudrate in bits/s. May be one of: 4800, 9600, 14400, 19200, 28800, 38400, 57600, 76800, 115200. Please be aware that lower baudrates are more reliable for long distance communication.
-
-\paragraph{Note 6}
-\label{holdingReg:note6}
-Writing the magic constant 0xABCD to this device will instruct the device to soft-reset.

-# Indoor Air Quality sensor IAQ01
-
-This repository contains all CAD files needed for making a Veles IAQ01 wired sensor, part of a family of [Veles Smart Household](#veles-smart-household) sensors.
-
-## Basic properties
-
-### Measured values
-
-* Carbon dioxide
-* Temperature
-* Relative humidity
-* Volatile Organic Compounds (VOC)
-* PM (particulate matter) [optional extension]
-
-### Connectivity
-
-* RS-485 with Modbus
-
-### Power requirements
-
-* Input voltage: 5 - 30 V DC
-
-### Status indication
-
-Sensor has a RGB LED, which shows current air quality status on a continuos scale from red to green. Limits for this full green / full red are user adjustable. Indication can be also configured to non-continuos "semaphore" mode, using only 3 colors (green / yellow / red). Intensity of the LED can be set (or the LED can be disabled entirely).
-
-## Where to get these sensors?
-
-We hope to be able to be to offer you these sensors in one way or another (fully assembled or some kits with PCBs and components). In the meantime, you can build one yourselves! You will need a bit of experience with PCB ordering, soldering, and flashing the firmware on STM32. Don't worry though, none of these require deep expertise. Also a 3D printer will come in handy, if you want some of those pretty enclosures. We suggest using white PETG - this makes the LED shine nicely through the front of the enclosure.

-## Veles Smart Household
-
-This sensor is part of Veles Smart Household. Goal of this project is to create open hardware and software platform for measuring various quantities, not only related to indoor air quality:
-
-* temperature
-* humidity
-* atmospheric pressure
-* carbon dioxide (CO2)
-* carbon monoxide (CO)
-* volatile organic compounds (VOC)
-* particulate matter (PM - dust particles)
-* light intensity
-* soil moisture
-
-... and some more!
-
-Sensors are connected either via RS-485 Modbus or wirelessly to central unit. Wireless sensors are currently in development. Central unit may be any anything that can read from the bus: any computer with RS-485 to USB converter (e.g. Raspberry Pi) or an actual PLC. Readout of the sensor is possible via Modbus: either using your own favourite application or using your Python package.
-
-**We want this to be community effort! Come help us make something great!**
-
-### Other Smart Household repositories
-
-* [RHT wired sensor](https://gitea.veleslabs.org/veles_labs/rht_sensor_wired)
-* [Python package](https://gitea.veleslabs.org/veles_labs/pyveles) for sensor readout and visualization (work in progress)
-    * Can be installed using `pip install veles`

+ *  Created on: Jul 18, 2021

+ *
+ *  Modbus slave RTU library (does NOT support ASCII and TCP)
+ *
+ *  Useful links:
+ *  https://www.picotech.com/library/oscilloscopes/modbus-serial-protocol-decoding
+ *  https://ipc2u.com/articles/knowledge-base/modbus-rtu-made-simple-with-detailed-descriptions-and-examples/

+ *  https://www.modbus.org/docs/Modbus_Application_Protocol_V1_1b.pdf
+ *
+ *  Note that byte order is big endian.
+ *
+ * USAGE:
+ *
+ * 1) Implement functions modbus_callback_function() and modbus_uart_transmit_function()
+ *      - modbus_uart_transmit_function() sends data via UART
+ *      - modbus_callback_function() does the real work: read sensors, set outputs...
+ *        note that when filling buffers (e.g. input_registers[]) user must
+ *        ensure that all data is big-endian
+ *    These functions are implementation-specific.
+ * 2) Set device address (variable modbus_device_address); you can do this either
+ *      - setting modbus_device_address directly (modbus.h needs to be included, duh)
+ *      - using modbus_set_device_address(uint8_t address) function
+ *    Or you can leave address as-is (MODBUS_DEFAULT_SLAVE_ADDRESS) and set it via
+ *    Modbus during runtime
+ * 3) Call modbus_process_msg() after message reception; you need to observe Modbus RTU timing:
+ *      - pauses between chars in frame are less or equal to 1.5 char
+ *      - pauses between frames are at least 3.5 chars (of silence)
+ *    For more information see section 2.5.1.1 (MODBUS Message RTU Framing)
+ *    in "MODBUS over Serial Line: Specification and Implementation Guide"
