Configuring Interrupt Priority Groups and Preemption on STM32F1 Microcontrollers

Overview of STM32F1 Interrupt Architecture The STM32F1 series, built on the ARM Cortex-M3 core, supports a significant number of interrupts. While the Cortex-M3 architecture theoretically supports 240 external interrupts, the STM32F103 line simplifies this by implementing 60 maskable interrupts alongside 16 internal exceptions. These interrupts ...
