Dec 23, 2025 · 3 min read · On a microcontroller, the heap is just a region of RAM used for dynamic allocation (e.g., malloc/new) at runtime. The big difference vs a PC is: RAM is tiny, there’s no OS to manage memory for you, and fragmentation can bite hard. 1) The memory map i...

Dec 22, 2025 · 1 min read · On STM32 there isn’t one single “SPI pin set” across all chips. SPI pins depend on the exact STM32 family/package and the pin alternate-function mapping. But the SPI signals are always the same: SCK (clock) MOSI (master out) MISO (master in) NSS/...
