An area of memory or a dedicated hardware circuit that is used to store incoming data. When the buffer is filled, new data are written starting at the beginning of the buffer. Circular buffers are ...

This application note presents an interrupt-driven UART for Z8 Encore! XP® and Z8 Encore! MC™ microcontrollers. It describes the UART register description, the circular buffer implementation, as well ...

The circular history buffer debugging technique uses a fixed amount of memory to hold the most recent software events leading up to the failure. Older software events are overwritten. Information ...

In the first part of this series, we discussed the need to perform power optimizations and exploration at higher levels of abstractions, where the potential to reduce the power consumption was highest ...

This course provides an introduction to Kernel programming for the Linux operating system, and the development of Linux kernel drivers for Embedded devices. The Yocto build system is introduced, which ...

In this online engineering course, you will gain experience writing low-level firmware to directly interface hardware with highly efficient, readable, and portable design practices. By completing this ...

Why Buffer? Because buffers cut you some slack. Inevitably, in our recent series on microcontroller interrupts, the question of how to deal with actual serial data came up. In those examples, we were ...
