For the uninitiated, MDKARM (Microcontroller Development Kit for ARM) is Keil’s proprietary IDE/compiler suite for ARM Cortex-M, Cortex-R, and legacy ARM7/9 cores. It’s the dusty, reliable workhorse of medical devices, automotive ECUs, and industrial robots—code that absolutely, positively cannot crash.
