WebSysTick Control and Status Register. The SysTick SYST_CSR register enables the SysTick features. The register resets to 0x00000000, or to 0x00000004 if your device does not … WebCalculating the RELOAD value. The RELOAD value can be any value in the range 0x00000001 - 0x00FFFFFF. You can program a value of 0, but this has no effect because the SysTick exception request and COUNTFLAG are activated when counting from 1 to 0. To generate a multi-shot timer with a period of N processor clock cycles, use a RELOAD value of N-1.

WebJun 28, 2024 · Similarly to basic timers, one of the most common uses for it is scheduling. Specifically for SysTick, it's common to have a 1ms interrupt and a variable associated with it (static - global for your SysTick.c, wrapped up into functions to return it). Every 1ms it gets incremented by 1 (32-bit variable will overflow after almost 50 days). WebDetailed Description. Hardware access layer for accessing the SYSTICK peripheral. SYSTICK is ARM peripheral, not Nordic design. It means that it has no Nordic-typical interface with Tasks and Events. Its usage is limited here to implement simple delays. Also keep in mind that this timer would be stopped when CPU is sleeping (WFE/WFI instruction ...
