Firmware that keeps your device working for years
Example code shows that a chip works; firmware in the field has to keep running.
Check yourself

Embedded and IoT
Sensors, firmware, machines and test set-ups: electronics that measure, control and report.
After this series you can:
- You choose a sensor, connection and power supply that fit each measuring spot.
- You name which step a machine or robot can take over, and what it must report.
- You record how every device is tested and where code, readings and documentation stay.
