/*
* modbus.h
*
* Created on: Jul 18, 2021
* Author: user
*
* 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://modbus.org/docs/Modbus_over_serial_line_V1_02.pdf
* 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"
