GCC,AMEG8 用GCC编译的AMEG8中的休眠指令是?
问 用
GCC编译的
AMEG8中的休眠指令是什么?我用SLEEP为什么不能通过?
答
1: 看gcc的手册5.5 Power Management and Sleep Modes
5.5.1 Detailed Description
#include < AVR/sleep.h>
Use of the SLEEP instruction CANallow your application to reduce it’s power com-sumption
considerably. AVRdevices CANbe put into different sleep modes by chang-ing
the SMn bits of the MCU Control Register ( MCUCR ). Refer to the datasheet for the
details relating to the device you are using.
Sleep Modes
Note:
Some of these modes are not available on all devices. See the datasheet for target
device for the available sleep modes.
• #define SLEEP MODE IDLE 0
• #define SLEEP MODE ADC BV(SM0)
• #define SLEEP MODE PWR DOWN BV(SM1)
• #define SLEEP MODE PWR SAVE ( BV(SM0) | BV(SM1))
• #define SLEEP MODE STANDBY ( BV(SM1) | BV(SM2))
• #define SLEEP MODE EXT STANDBY ( BV(SM0) | BV(SM1) | BV(SM2))
Sleep Functions
• void set sleep mode (uint8 t mode)
• void sleep mode (void)
答 2: 是啊,要用setsleepmode()和sleepmode()才行或者这样也可以:
asm volatile("sleep"::);
注意这之前要先设置睡眠模式。
