KEAZ128参考手册是不是少了一章讲NVIC的？

yezhenke · 发表于 2015-9-16 15:37:22

在看别人的程序NVIC_ICPR |= 1 << (22 % 32);
NVIC_ISER |= 1 << (22 % 32);  /*for PIT0*/

NVIC_ICPR |= 1 << (23 % 32);
NVIC_ISER |= 1 << (23 % 32);  /*for PIT1*/

NVIC_ICPR |= 1 << (15 % 32);
NVIC_ISER |= 1 << (15 % 32);  /*for ADC*/

去参考手册上找完全没有这几个寄存器的介绍啊

所有M0的芯片外设中断号都是一样的？

这个是在ARM 的手册里有介绍

外设中断号参见官方库中vector.c vector.h ISR.h这几个文件

以下是KE系列的官方库
vector.h中定义

工程文件 ISR.h中（以ACMP为例）
#undef  VECTOR_032
#define VECTOR_032 ACMP0_Isr

#undef  VECTOR_037
#define VECTOR_037 ACMP1_Isr

extern void ACMP0_Isr(void);
extern void ACMP1_Isr(void);

具体流程明白了吧

l明白了辛苦了

多谢啦！
