软件配置的时候说
To control a stepper motor following the typical run profile, the software uses three interrupts, a DMA interrupt during acceleration, a SysTick interrupt and another DMA interrupt during deceleration. These interrupts are generated every 38 ms.
有个流程图中说Enable Systick interruptfor 8 ms
官网例程中说每38ms产生一次中断。这不是矛盾吗?谁能告诉我这是怎么算出来的,谢谢! |
