Interrupt Cautions: Arduino Course 9.5

This lesson covers the complexities of using interrupts in programming, particularly in C++ and Arduino. It explains how interrupts can occur at any point, even in the middle of a line of code, and the potential issues this can cause. The lesson provides a detailed analysis of an Arduino program, highlighting problems with data corruption when interrupts occur. It introduces the use of noInterrupts() and interrupts() functions to manage these issues safely. Practical considerations and debugging challenges are discussed, along with strategies for handling flags in interrupt service routines.

How does the timing of interrupts affect the integrity of data?

What strategies can be employed to debug issues related to interrupts?

What is the role of flags in managing interrupts?

In what scenarios might you want to limit the execution of code in an interrupt service routine?
