System configuration example
Development environment
Development can be done using CodeFusion Studio™ (CFS) provided by Analog Devices.
CodeFusion Studio™ is a VS Code-based integrated development environment that unifies project management, code editing, building, and debugging.
By combining it with the Microcontroller SDK (MSDK), you can efficiently develop firmware for IoT.
Provided sample code
1. Sensor acquisition
Initializes the connected I2C sensor, acquires data, and outputs it to the PC.
2. Sigfox transmission
The acquired data is converted into Sigfox transmission format and transmitted via the network.
3. Power saving control
It periodically performs sensor measurements and outputs data while repeating sleep and wake cycles.
4. Integrated Actions
Sensor acquisition → Sigfox transmission → PC output is performed in a series.
