But I am puzzled as to why 2 is the offset, when the core_cm0.h file and your own earlier posts indicate that the offset should be 8. The following is a snippet from core_cm0.h starting at line 408:

WebMay 6, 2024 · The systick is essentially a 24-bit timer counter running at 48MHz that ticks down to zero. At the beginning of each cycle the systick timer is loaded with the value 47999. At 48MHz it takes exactly 1ms for the timer to reach zero (underflow), whereupon it’s reloaded and continues to count down oncemore. WebSep 28, 2024 · The fundamental difference between the systick and peripheral interrupts is that the systick is specified by ARM to be at IRQ 6 (0x003C) when it is available in the core. It is also part of the ARM Cortex, clocked by the same clock and thus synchronous.
WebMar 24, 2016 · You can, if your processor allows it (it should, since I believe all of that series are Cortex M4 based), set the Systick Interrupt to a higher priority than the other interrupts and then find out if you can make your compiler/processor not turn off interrupts globally while processing an interrupt.
WebBy default, the STM32Cube HAL is built around a unique timebase source which is the ARM-Cortex system timer (SysTick). However, HAL-timebase related functions are defined as weak so that they can be overloaded to use another hardware timebase source.
