Embedded Systems and Microcontrollers: A Market Entering Its Next Phase
Embedded systems have long been the quiet backbone of modern electronics. From industrial controllers and automotive ECUs to consumer electronics and medical devices, microcontrollers and
Refactoring: Improving the Design of Existing Code
Refactoring is a disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior. Coined and popularized by
The Interrupt Pattern in Embedded Systems
Introduction In embedded systems, responsiveness and timing precision are often critical. When a hardware event occurs — such as a GPIO edge, UART byte received,
The Polling Pattern in Embedded Systems
Introduction In many embedded systems, it’s not always possible — or practical — to use interrupts. Some peripherals don’t provide interrupt lines, others generate events
