Reliable Embedded Systems: Recovering Arduino i2c Bus Lock-ups

It’s not unheard of for the i2c bus to “lock-up” on you, which can stop your system from working. If you are trying to operate a remote or embedded system, this is not ideal. This article discusses techniques that you can use to try and make your system more fault-tolerant and attempt to recover from […]

Reliable Embedded Systems: Using The Arduino Watchdog With Crash Tracking

The previous article in this series introduced the “Watchdog Timer “ as a tool to use to build more reliable systems; it will reset the Arduino processor in the event of the application locking up. However, as in medicine, this is like treating the symptom and not the cause. Why did the application lock-up in

Reliable Embedded Systems: Using The Arduino Watchdog With Sleepy Pi

A previous article in the series introduced the concept of the Arduino Watchdog Timer and its value in developing more reliable embedded systems. When developing systems based on the Sleepy Pi platform, we make extensive use of an Arduino library to put the Arduino to sleep. In some cases, this library uses the watchdog internally
