Installation Setup

Install compiler/toolchain (GCC, IAR, Keil, or PlatformIO)

Install IDE (VS Code, Eclipse, CLion, or vendor IDE)

Set up hardware debugging tools (JTAG/SWD)

Configure build system/project files

Connect target board or microcontroller

Environment Setup

Install compiler toolchain

Set PATH for CLI tools

Install debugger/programmer

Set up IDE and project

Connect development board

Config Files

Makefile or CMakeLists.txt

project.elf / .hex output

linker scripts (.ld)

startup assembly files

device-specific headers

Cli Commands

make or gprbuild - build project

arm-none-eabi-gcc - compile for ARM

openocd - flash/debug via JTAG/SWD

objdump / nm - inspect binaries

gdb - debugging firmware

Internationalization

Code supports Unicode in comments

Embedded libraries portable globally

Toolchains available worldwide

Documentation can be localized

Open-source frameworks support multiple regions

Accessibility

Readable structured code

Well-commented hardware mappings

Clear modular drivers

Consistent naming conventions

Portable across boards

Ui Styling

Embedded C/C++ is mostly backend; UI minimal

LEDs, serial console output

Small displays via SPI/I2C

Custom protocol communication

Debug interfaces for telemetry

State Management

Global/static variables for persistent state

Use volatile for hardware-mapped variables

Critical section protection for concurrency

RTOS task-local state

Stack and heap management

Data Management

Memory-mapped I/O registers

Static vs dynamic allocation

Buffers for communication

Queues and circular buffers

Persistent configuration in flash
