• Relative Priorities of SVC, PendSV, Systick in RTOSes
    I know that RTX uses the following system exception priorities, on my MCU (silabs efm32gg, CM3-based) with 3 priority bits SVC = 6 PendSV = Systick = 7, where lower numeric value is higher priority...
  • How to read the SysTick timer value?
    1. I want to know what is RTX SysTick timer? 2 Or how to read its current value? 3. How to start SysTick timer before RTX if it is possible? I'd prefer to use library functions but failed to find...
