中斷是快進(jìn)快出，一般是不會(huì)影響藍(lán)牙的運(yùn)行情況。

注意不要在中斷里面調(diào)用的函數(shù)在FLASH運(yùn)行并且頻繁進(jìn)出中斷，可以在函數(shù)上方加上highcode，放在RAM中運(yùn)行。

需要注意函數(shù)的聲明：void?EXTI0_IRQHandler(void)?__attribute__((interrupt("WCH-Interrupt-fast")));

如果是驅(qū)動(dòng)電機(jī)，則需要注意供電是否跟電機(jī)的供電分開(kāi)，因?yàn)殡姍C(jī)工作需要的電流比較大，可能造成無(wú)法驅(qū)動(dòng)藍(lán)牙射頻，因此可以先單獨(dú)測(cè)試藍(lán)牙不測(cè)試電機(jī)，排除電機(jī)干擾。
