Bit Manipulation
Many peripherals on the T-Watch, such as the PCF8563 real-time clock and various sensor registers, store multiple pieces of information packed into individual bits within a single byte. Understanding bit…
Pointers and References
Pointers and references are core to writing efficient, hardware-aware C and C++ code. In embedded systems, they are used constantly to interact with memory, hardware registers, and shared data structures.…
Modular Architecture
In professional embedded systems, firmware is rarely written as a single file. Instead, it is structured to be modular, maintainable, and scalable so that systems can grow, be debugged efficiently,…
