Stack

NULL dereference, dangling pointers, out-of-bounds array access, undefined behavior — we deliberately trigger the classic pointer land mines of embedded development and observe them under the debugger. Knowing how things break is the most powerful way to learn.

C variable declarations (const, global, local) determine which memory region data lands in. Use the debugger to verify actual addresses and understand the difference and purpose of Flash, SRAM, and the Stack.
