Embedded Systems Study Notes

A meticulously crafted collection of handwritten notes covering a wide range of topics in computer science and electronics. These notes are perfect for students studying digital electronics, computer architecture, and C fundamentals. The clear, organized, and color-coded format makes complex subjects easy to understand and review. Topics Covered: Binary and Number Systems: In-depth explanations of binary algebra (addition, subtraction, multiplication), conversion between decimal, binary, and hexadecimal systems, and the underlying logic. Digital Logic: Detailed notes on logic gates (NOT, AND, OR, NOR, NAND, XOR, buffer), truth tables, timing diagrams, and logic identities. The notes also cover Boolean identities and Karnaugh Maps for circuit simplification. Computer Architecture: A clear breakdown of microcontroller components, including the CPU, memory, and bus systems. Concepts like Von Neumann vs. Harvard architecture, RISC vs. CISC, and memory storage formats (Little Endian vs. Big Endian) are explained with diagrams and examples. Microcontrollers and Peripherals: This section provides practical insights into microcontrollers, specifically the STM32F0 series. It includes notes on GPIO (General Purpose Input/Output) functionality, different pin configurations (Push-Pull), and the use of Timers, ADCs (Analog-to-Digital Converters), and Interrupts. The notes also include code snippets for common tasks like toggling an LED and LCD control. C Fundamentals: A solid foundation in C programming tailored for embedded systems. This includes data types, operators, conditional statements (if-else, switch), loops (for, while, do-while), and fundamental concepts like arrays, pointers, and memory storage classes (auto, register, static, extern). Compilation Process: A step-by-step overview of how C code is compiled and linked, explaining the roles of the preprocessor, compiler, assembler, and linker. Encoders, Decoders & Multiplexers: Illustrated explanations of these essential digital logic components with corresponding truth tables and circuit diagrams.
