In this next installment of our motor control series, we examine challenges and methods for memory management needed to ensure predictable and deterministic behavior of motor control applications. Effective programming practices for real-time embedded applications typically emphasize allocating values on the stack wherever feasible. However, in certain scenarios, such as when the size of a value is unknown or vectors dynamically grow over time, this approach may not be possible. Under these circumstances, it becomes necessary to dynamically allocate memory from the heap. This ensures efficien ..read more

What can we expect from IoT development in the future? What approaches should developers take to create next-generation IoT applications efficiently?

In this installment, you will see how to apply Assertions and Design by Contract (DBC) concepts to embedded systems. In the previous episode of this series, you learned what assertions and Design by Contract (DBC) are, how to think of them, and how to use them properly. Today, you will see how to apply these concepts to embedded systems. Lesson 48 Assertions and Design by Contract, Part-2 Embedded Assertions The last lesson introduced the standard assert() macro from the C library. However, in embedded systems, you almost always have to define customized assertions [1], which isn’t complicat ..read more

This article explores one of the simulation methods that can be utilized to identify and optimize device/component selection in noise sensitive applications. This article explores one of the simulation methods that can be utilized to identify and optimize device/component selection in noise sensitive applications. We will first point out one of the features of LTspice®simulation that allows this for standard components and then introduce an approach that allows this same capability for operational amplifiers (op amps) used in a signal path. Since low noise is often associated with higher powe ..read more
