Intermediate Topic 25 of 50 Mobile, Embedded & IoT
Memory Constraints
Writing code for tiny RAM and flash budgets.
How it works
MCUs may have 2–512 KB RAM; use flash for constants (PROGMEM), small types, static buffers, stack-depth analysis and map files to track usage.
Where it is used
Fitting in tiny devices.
Common pitfall
Stack overflows silently corrupt data.
Where it fits in the course
Memory Constraints is topic 25 of 50 in Mobile, Embedded & IoT, rated Intermediate. It follows Embedded C. The next topic is Bootloaders.
