Verify all pins are properly seated + +### Power the Board + +The shield can be powered through multiple sources: + +- **A - USB Power**: Via the host board USB connection. +- **B - Power Jack**: Via the host board power jack. +- **C - External Power**: Through the VIN screw terminal (7.0 to 24.0 V). +***Note: The UNO SPE Shield can safely operate with a 24 VDC power supply. While the Arduino UNO R4 is designed to handle this voltage without issue, caution is advised, 24 V can potentially damage UNO R3 boards or any third-party UNO-compatible board.*** +- **D - Power over Data Line (PoDL)**: Through the T1SP screw terminal or dedicated connector. + +![Powering your board](assets/SPE-power.gif) + +## Simple Broadcast Example + +This example demonstrates a simple broadcast communication system between multiple nodes on an SPE network. Each node can broadcast messages to all other nodes, and automatically responds with "pong" when it receives a "ping" message. This creates an interactive network where you can test connectivity and response times between different devices. + +![Overview of the Ping/Pong example](assets/SPE-ping-pong-01.gif) + +### Hardware Setup + +1. **Configure Termination Jumpers**: For point-to-point connections, close the termination jumpers on both shields +2. **Connect the SPE Cable**: Wire the twisted pair between the two shields' SPE screw terminals or using a T1S dedicated cable. +3. **Power Both Systems**: Ensure both Arduino boards are powered + +### Sketch + +The system uses UDP broadcasting to send messages to all nodes simultaneously, making it perfect for testing your SPE network setup and verifying that all nodes are communicating properly. Each node operates independently, listening for incoming messages while also being able to send its own broadcasts. + +**Important**: Before uploading this code to each board, you must change the `NODE_ID` constant to a unique value between 0 and 7. Each node on the network must have a different ID to ensure proper communication and avoid conflicts. For example: +- First board: `MY_NODE_NUMBER = 0;` +- Second board: `MY_NODE_NUMBER = 1;` +- Third board (optional): `MY_NODE_NUMBER = 2;` + +Remember that any termination nodes should have the termination headers properly closed, more info on the [Arduino UNO SPE Shield datasheet](https://docs.arduino.cc/resources/datasheets/ASX00073-datasheet.pdf). + +The node ID determines the device's IP address (192.168.42.100 + NODE_ID) and its position in the PLCA (Physical Layer Collision Avoidance) cycle. When you type a message in the Serial Monitor and press Enter, it's broadcast to all nodes on the network. If any node receives the word "ping", it automatically responds with "pong" to the sender. + +```arduino +// Simple 10BASE-T1S Ping-Pong Network +// Each board can send messages to all others +// Automatically replies "pong" when it receives "ping" + +#include +#include + +// CHANGE THIS NUMBER FOR EACH BOARD (0, 1, 2, 3, etc.) +const int MY_NODE_NUMBER = 0;

The system uses SPE (Single Pair Ethernet) for the main network backbone and RS-485 for connecting to end devices, combining the benefits of modern Ethernet with the reliability of industrial serial communication. + +The architecture consists of three layers: a central control node that issues commands, gateway nodes that translate between SPE and RS-485 protocols, and Opta boards that execute the actual control operations. This design allows for scalable industrial automation where multiple Opta boards can be distributed across a facility while being managed from a single control point. + +### Central Control Node (Server) + +The central control node (Node 7) acts as the command center of the system, sending LED control commands to specific Opta boards through their associated gateway nodes. Operating on the SPE network, this node provides a simple serial interface where operators can type commands like "LED 3" to toggle the LEDs on remote Optas. + +![Central SPE Controller](assets/SPE-rs485-transducer-main.png) + +```arduino +// SPE Server Node 7 - Sends LED commands +#include +#include + +const uint8_t MY_ID = 7; + +IPAddress myIP(192, 168, 42, 107); +IPAddress netmask(255, 255, 255, 0); +IPAddress gateway(192, 168, 42, 100); + +TC6::TC6_Io* io; +TC6::TC6_Arduino_10BASE_T1S* network; +Arduino_10BASE_T1S_UDP* udp; + +void setup() { + Serial.begin(115200); + delay(1000); + + Serial.println("\nSPE LED Control Server"); + Serial.println("Type: LED 0, LED 1, etc.\n"); + + io = new TC6::TC6_Io(SPI, CS_PIN, RESET_PIN, IRQ_PIN); + network = new TC6::TC6_Arduino_10BASE_T1S(io); + udp = new Arduino_10BASE_T1S_UDP(); + + pinMode(IRQ_PIN, INPUT_PULLUP); + attachInterrupt(digitalPinToInterrupt(IRQ_PIN), []() { + io->onInterrupt(); + }, FALLING); + + io->begin(); + + MacAddress mac = MacAddress::create_from_uid(); + T1SPlcaSettings plca(MY_ID); + T1SMacSettings mac_settings; + + network->begin(myIP, netmask, gateway, mac, plca, mac_settings); + network->digitalWrite(TC6::DIO::A0, false); + network->digitalWrite(TC6::DIO::A1, false); + + udp->begin(8888); + + Serial.println("Ready!"); +} + +void loop() { + network->service(); + + if (Serial.available()) { + String cmd = Serial.readStringUntil('\n'); + cmd.trim(); + cmd.toUpperCase(); + + if (cmd.startsWith("LED ")) { + int node = cmd.substring(4).toInt(); + IPAddress targetIP(192, 168, 42, 100 + node); + + udp->beginPacket(targetIP, 8888); + udp->print(cmd); + udp->endPacket(); + + Serial.print("Sent to node "); + Serial.println(node); + } + } +} +``` + +### Transducer Node SPE/RS-485 + +The gateway nodes serve as protocol translators between the SPE network and RS-485 devices. Each gateway consists of an Arduino board with an SPE shield, where the board's hardware serial port (Serial1) connects to the RS-485 transceiver on the shield. These nodes receive UDP packets from the SPE network, extract the command data, and forward it to the RS-485 bus. + +![Shields Addressing the Endpoints Across Protocols](assets/SPE-rs485-transducer-transducer.png) + + +```arduino +// SPE/RS-485 Gateway +#include +#include + +const uint8_t MY_ID = 0; // Change for each gateway + +IPAddress myIP(192, 168, 42, 100 + MY_ID); +IPAddress netmask(255, 255, 255, 0); +IPAddress gateway(192, 168, 42, 100); + +TC6::TC6_Io* io; +TC6::TC6_Arduino_10BASE_T1S* network; +Arduino_10BASE_T1S_UDP* udp; + +void setup() { + Serial.begin(115200); + Serial1.begin(9600); + delay(1000); + + Serial.print("\nGateway Node "); + Serial.println(MY_ID); + + pinMode(7, OUTPUT); // RS485_DE + pinMode(8, OUTPUT); // RS485_RE + digitalWrite(7, HIGH); + digitalWrite(8, HIGH); + + io = new TC6::TC6_Io(SPI, CS_PIN, RESET_PIN, IRQ_PIN); + network = new TC6::TC6_Arduino_10BASE_T1S(io); + udp = new Arduino_10BASE_T1S_UDP(); + + pinMode(IRQ_PIN, INPUT_PULLUP); + attachInterrupt(digitalPinToInterrupt(IRQ_PIN), []() { + io->onInterrupt(); + }, FALLING); + + io->begin(); + + MacAddress mac = MacAddress::create_from_uid(); + T1SPlcaSettings plca(MY_ID); + T1SMacSettings mac_settings; + + network->begin(myIP, netmask, gateway, mac, plca, mac_settings); + network->digitalWrite(TC6::DIO::A0, false); + network->digitalWrite(TC6::DIO::A1, false); + + udp->begin(8888); + + Serial.println("Ready!"); +} + +void loop() { + network->service(); + + if (udp->parsePacket()) { + char buffer[64] = {0}; + udp->read((byte*)buffer, 63); + + String cmd = String(buffer); + cmd.trim(); + + if (cmd == "LED " + String(MY_ID)) { + Serial1.println("T"); + Serial1.flush(); + Serial.println("Toggle sent"); + } + } +} +``` + +### Opta RS-485 Interface + +The Arduino Opta boards represent the end devices in this system, receiving commands via RS-485 and executing the requested actions. + +![Opta as Endpoint](assets/SPE-rs485-transducer-end.png) + +When an Opta receives a command, it parses the instruction, performs the requested operation.
