The proposed architecture provides reliable, low-latency communication among distributed sensors, control panels, and actuators, while supporting scalability, fault tolerance, and regulatory compliance. By organizing devices in a hierarchical tree structure, the network optimizes routing efficiency, reduces RF congestion, and enables deterministic message delivery essential for safety‑critical systems. ## Solution Diagram

## Bill of Materials | TOOLS | QUANTITY |-- |-- | [SAMC21 Xplained Pro Evaluation Kit](https://www.microchip.com/en-us/development-tool/atsamc21-xpro) | 1 | [mikroBUS Xplained Pro](https://www.microchip.com/en-us/development-tool/atmbusadapter-xpro) | 1 | [ATA8510 Curiosity Board](https://www.microchip.com/en-us/development-tool/ev82m22a) | 2 - 5 ## Board programming The `/hex` folder contains the compiled application HEX files. | Device | Target board | Hex file |-- |-- |-- | Central| SAMC21 Xplained Pro | [central.hex](./hex/central,hex) | Sensor | ATA8510 Curiosity | [sensor.hex](./hex/sensor.hex) The EEPROM configuration [ATA8510_EEPROM.hex](./hex/ATA8510_EEPROM.hex) file is applicable to both the central and sensor applications. Refer to the [Central](apps/central/README.md) and [Sensor](apps/sensor/README.md) documentation for the respective procedures to program each board. ## EEPROM Configuration The EEPROM Configuration Tool has been used to generate the configuration data file required for EEPROM programming. The EEPROM configuration [ATA8510_EEPROM.hex](./hex/ATA8510_EEPROM.hex) is common to all device types and is shared across all ATA8510 Curiosity Boards. Users can customize the EEPROM configuration, including RF parameters such as frequency, data rate, modulation, bandwidth, deviation, etc., as needed using the EEPROM Configuration Tool. EEPROM Configuration Tool can be downloaded from the software section of ATA8510 [product page](https://www.microchip.com/en-us/product/ata8510#Tools%20And%20Software). The screenshot shows the Service Configuration for Service 0 (433 MHz). It is used in the demo application

The screenshot shows the Service Configuration for Service 1 (868 MHz). It has not been tested yet.

## Applications The demo is structured into multiple projects. Refer to the following sections for detailed information on each. | Section | Description | | :- | :- | | [Apps](./apps/README.md) | This resource provides detailed descriptions of the implemented state machines, along with additional definitions illustrated using flowcharts. | | [Central](./apps/central/README.md) | Technical details specific to the Central device | | [Sensor](./apps/sensor/README.md) | Technical details that are specific to the Sensor device | [TOP](#contents) ## Run the demo ### System startup 1. Power the Central device via the Debug USB connector 2. Open a serial Terminal (115200 8 N 1) 3. Press the Reset button 4. Observe the console output on the Central device - `STATE_INIT`: Central device is intitialized after Reset - `STATE_WAIT_RF_SYS_RDY`: The RF is initialized - `STATE_IDLE`: The central device is in Idle state - `%00000000;03D4%`: Status of format `%;%` ``` ... >>> STATE_INIT <<< >>> STATE_WAIT_RF_SYS_RDY <<< >>> STATE_IDLE <<< %00000000;03D4% ... ``` ### Add a new sensor #### Learning mode 1.
