WebMar 10, 2024 · It should be the other way around - the SysTick_Handler gets called first than the eternal hook function gets executed and return 1 to stop the handler from using local code. I think the local code is just WDT timeout, and that is not happening either. My problem is the SysTick_Handler never fires. I am missing some "enable SysTick" code somewhere. Web若想透過 SysTick 在固定的時間內產生一個事件，比如說 1ms，那可透過另外一個 Calibration register 的數值來 scale 給定的 reload register 值，Calibration register 是唯讀的暫存器，其數值表示 10 ms (SysTick 的 reload 週期) 的整數倍
