/** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad * Copyright (C) 2013-2019 Sensnology AB * Full contributor list: https://github.com/mysensors/MySensors/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * DESCRIPTION * The RS485 Gateway prints data received from sensors on the serial link. * The gateway accepts input on seral which will be sent out on * the RS485 link. * * Wire connections (OPTIONAL): * - Inclusion button should be connected between digital pin 3 and GND * - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series * * LEDs (OPTIONAL): * - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly * - ERR (red) - fast blink on error during transmission error or receive crc error * * If your Arduino board has additional serial ports * you can use to connect the RS485 module. * Otherwise, the gateway uses AltSoftSerial to handle two serial * links on one Arduino. Use the following pins for RS485 link * * Board Transmit Receive PWM Unusable * ----- -------- ------- ------------ * Teensy 3.0 & 3.1 21 20 22 * Teensy 2.0 9 10 (none) * Teensy++ 2.0 25 4 26, 27 * Arduino Uno 9 8 10 * Arduino Leonardo 5 13 (none) * Arduino Mega 46 48 44, 45 * Wiring-S 5 6 4 * Sanguino 13 14 12 * */ // Enable debug prints to serial monitor #define MY_DEBUG // Enable RS485 transport layer #define MY_RS485 // Define this to enables DE-pin management on defined pin #define MY_RS485_DE_PIN 2 // Set RS485 baud rate to use #define MY_RS485_BAUD_RATE 9600 // Enable this if RS485 is connected to a hardware serial port //#define MY_RS485_HWSERIAL Serial1 // Enable serial gateway #define MY_GATEWAY_SERIAL // Enable inclusion mode #define MY_INCLUSION_MODE_FEATURE // Enable Inclusion mode button on gateway #define MY_INCLUSION_BUTTON_FEATURE // Set inclusion mode duration (in seconds) #define MY_INCLUSION_MODE_DURATION 60 // Digital pin used for inclusion mode button #define MY_INCLUSION_MODE_BUTTON_PIN 3 // Set blinking period #define MY_DEFAULT_LED_BLINK_PERIOD 300 // Flash leds on rx/tx/err #define MY_DEFAULT_ERR_LED_PIN 4 // Error led pin #define MY_DEFAULT_RX_LED_PIN 5 // Receive led pin #define MY_DEFAULT_TX_LED_PIN 6 // the PCB, on board LED #include void setup() { // Setup locally attached sensors } void presentation() { // Present locally attached sensors } void loop() { // Send locally attached sensor data here }
