Intermediate Topic 24 of 50 Mobile, Embedded & IoT

Embedded C

Resource-conscious C programming for firmware.

How it works

Firmware C uses fixed-width types (uint8_t), bit manipulation on registers, volatile for hardware, static allocation, interrupts and careful memory layout; avoid malloc and recursion.

Where it is used

Writing for microcontrollers.

Common pitfall

Integer promotions and endianness bugs.

Where it fits in the course
