Variables & Data Types
Understand how C represents integers, characters, signedness and fixed-width values in embedded firmware.
CORE IDEA
Choose types deliberately
ENGINEERING VIEW
Understand width and signedness
WHAT TO WATCH
Use uint8_t/uint16_t/uint32_t where appropriate
REMEMBER
Avoid assumptions about implementation-defined behavior
Engineer’s checklist
- Choose types deliberately
- Understand width and signedness
