📡 CMSIS-DAP-Communicator 📡

Communicate through CMSIS-DAP with the PSoC6 / Onethinx OTX-18 Core module

Firmware and Software for the Onethinx Core OTX-18 module — an ultra-compact, production-ready LoRaWAN® module powered by PSoC6.

This firmware demonstrates memory communication, configuration provisioning, and runtime diagnostics using a CMSIS-DAP programmer. It includes direct USB HID communication support via a simple .NET utility.

🔧 Key Features

• Memory-mapped command structure (CommData_t) for easy interaction
• LoRaWAN® key management (OTAA/ABP, 10x/11x)
• Firmware build metadata and diagnostics
• LED control and sensor implementation
• Pre-configured LoRaWAN® stack support
• UART-based printf() logging using a lightweight drop-in (PrintF.c/h)

---

💻 PC-Side Communication Utility

A .NET 8 desktop app is included to communicate with the module via CMSIS-DAP over USB HID. It allows you to:

• View and edit LoRaWAN keys
• Read sensor values (Light intensity throug ADC on the OTX-18 DevKit)
• Query LoRaWAN Stack and Firmware info
• Toggle I/O such as LEDs

⚡ Getting Started

Firmware

1. Open the project in Visual Studio Code (check OTX18-Project-Examples for more information)
2. Connect a CMSIS-DAP compatible programmer.
3. Build and flash the firmware.

PC Utility

1. Open CmsisDap_Communicator.sln in Visual Studio 2022+
2. Build and run.
3. Connect to the OTX-18 module and start interacting!
