The NVIC supports up to 16 priority levels, allowing critical system routines (such as motor emergency stops) to pre-empt lower-priority routines (such as refreshing a display). Direct Memory Access (DMA)
12-bit resolution translates analog voltages (0 to 3.3V) into a digital scale from 0 to 4095. STM32 pins are highly multiplexed
The STM32F103 is a popular 32-bit ARM Cortex-M3 microcontroller from STMicroelectronics, belonging to the STM32F1 series. It is widely used in embedded systems education and industrial applications due to its balance of performance, power efficiency, and peripheral integration.
