WiDo定时器程序编译不通过

TIMER_INTR_NAME预定义如下：
#if defined(__AVR_ATmega32U4__)
#define TIMER_INTR_NAME TIMER1_OVF_vect
#else
#define TIMER_INTR_NAME TIMER2_OVF_vect
#endif

相应的定时器中断处理如下：
ISR(TIMER_INTR_NAME) {
#if defined (__AVR_ATmega168__) || defined (__AVR_ATmega48__) || defined (__AVR_ATmega88__) || defined (__AVR_ATmega328P__) || defined (__AVR_ATmega1280__) || defined (__AVR_ATmega2560__)

#elif defined (__AVR_ATmega32U4__)

TCNT1L = 0;
#endif

谢谢各位，可是加载了那个库之后编译还是不通过

上图是atmega32U4的定时器概述，截图自atmega32u4的数据手册，确实没有定时器2。
因此那个库的意思应该是，如果使用了Leonardo，那么切换到它的定时器4来兼容，防止没有定时器2出现错误。

我记得没有错的话，atmega32u4内核的主控是没有timer2的。。。。o(╯□╰)o
楼主你可以了解下timer4，路线二是去搜一下google，arduino leonardo compatible timer library。。。

因为你的库文件没有更新,你的库里面没有更新,在libraries\MsTimer2文件夹里的MsTimer2.cpp里面写的,你的库应该没有这句话,不知道我说的对不对

库文件压缩包我放附件里了,你试试看,能否解决

恩恩，但是都是AVR的处理器啊，Leonardo是ATmega32U4，也有定时器2

wido 好像是Leonardo，不是UNO的主控吧
