WebApr 11, 2024 · Usually the cycle counter is already enabled after start, but it does not hurt to re-enable it. In the status bar of Embedded Studio you can see the cycle counter, too (as xxx,xxx Cycles). You could check if it is running there. WebMay 21, 2015 · 3. Your code has two problems: You don't know whether the interrupt that increased SysTickMajor happened before or after you read the timer value into time. Operations on 64-bit values are not atomic on a 32-bit system. So the value for SysTickMajor could be updated by the interrupt between reading the two 32-bit words.
