STM32f0C8T6睡眠模式到底能不能用？

问答对人有帮助，内容完整，我也想知道答案 0 最近在做一个很简单的程序，然后客户必须要低功耗，开始用STC的单片机由于要使用5个1外部中断实现低功耗唤醒，功能实现不了，换STM32来是，产考了很多资料但不管怎么样就是进不了睡眠模式，要不就是进入了睡眠模式但却不能唤醒，而且用电流表测量电流竟然达到了40mA，折腾了好多天也一直没有个结果。有没有大神指导下的！下面是我参考官方例程写的程序！！ int main(void) { SYS_HSI_CLK_Config(); if (Systick_Config(SystemCoreClock / 1000)) { while (1);//²¶»ñ´íÎó } RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE); PWR_BackupAccessCmd(ENABLE); RCC_BackupResetCmd(ENABLE); RCC_BackupResetCmd(DISABLE); SleepMode_Measure(); LED_IO_Init(); while (1) { switch(mode) { case 1:SW_1() ;break; case 2:SW_2() ;break; case 3:SW_3() ;break; case 4:SW_4() ;break; case 5:SW_5() ;break; default: __WFI(); break; // Sys_Standby();rest_all(GPIOA,OUT_DATA,~OUT_DATA); } //test(); GPIOC->ODR \|=0x2000; Delay(50); GPIOC->ODR =~0x2000; Delay(50); } } void SleepMode_Measure() { __IO uint32_t index = 0; GPIO_InitTypeDef GPIO_InitStructure; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA \| RCC_AHBPeriph_GPIOB \| RCC_AHBPeriph_GPIOC, ENABLE); GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AN; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_All; GPIO_Init(GPIOA, GPIO_InitStructure); GPIO_Init(GPIOB, GPIO_InitStructure); GPIO_Init(GPIOC, GPIO_InitStructure); RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA \| RCC_AHBPeriph_GPIOB \| RCC_AHBPeriph_GPIOC, DISABLE); EXTI0_1InitConfig(); EXTI2_3InitConfig(); EXTI4_15InitConfig(); __WFI(); /* while (1) { for(index = 0; index < 0x7FFFF; index++); } */ } void EXTI0_1InitConfig(void) { //Enable GPIOA clock RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE); // Configure PA0 pin as input floating GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL; GPIO_Init(GPIOA, GPIO_InitStructure); // Enable SYSCFG clock RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE); // Connect EXTI0 Line to PA0 pin SYSCFG_EXTILineConfig(EXTI_PortSourceGPIOA, EXTI_PinSource1); // Configure EXTI1 line EXTI_InitStructure.EXTI_Line = EXTI_Line1; EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt; EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Rising; EXTI_InitStructure.EXTI_LineCmd = ENABLE; EXTI_Init( EXTI_InitStructure); // Enable and set EXTI0 Interrupt NVIC_InitStructure.NVIC_IRQChannel = EXTI0_1_IRQn; NVIC_InitStructure.NVIC_IRQChannelPriority = 0x00; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init( NVIC_InitStructure); } void EXTI2_3InitConfig(void) { //Enable GPIOA clock RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE); // Configure PA0 pin as input floating GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2\|GPIO_Pin_3; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL; GPIO_Init(GPIOA, GPIO_InitStructure); // Enable SYSCFG clock RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE); // Connect EXTI0 Line to PA2 pin SYSCFG_EXTILineConfig(EXTI_PortSourceGPIOA, EXTI_PinSource2); // Connect EXTI0 Line to PA3 pin SYSCFG_EXTILineConfig(EXTI_PortSourceGPIOA, EXTI_PinSource3); // Configure EXTI2 line EXTI_InitStructure.EXTI_Line = EXTI_Line2; EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt; EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling; EXTI_InitStructure.EXTI_LineCmd = ENABLE; EXTI_Init( EXTI_InitStructure); // Configure EXTI3 line EXTI_InitStructure.EXTI_Line = EXTI_Line3; EXTI_Init( EXTI_InitStructure); // Enable and set EXTI2-3 Interrupt NVIC_InitStructure.NVIC_IRQChannel = EXTI2_3_IRQn; NVIC_InitStructure.NVIC_IRQChannelPriority = 0x01; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init( NVIC_InitStructure); } void EXTI4_15InitConfig(void) { //Enable GPIOA clock RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE); // Configure PA0 pin as input floating GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4\|GPIO_Pin_5; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL; GPIO_Init(GPIOA, GPIO_InitStructure); // Enable SYSCFG clock RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE); // Connect EXTI0 Line to PA4 pin SYSCFG_EXTILineConfig(EXTI_PortSourceGPIOA, EXTI_PinSource4); // Connect EXTI0 Line to PA5 pin SYSCFG_EXTILineConfig(EXTI_PortSourceGPIOA, EXTI_PinSource5); // Configure EXTI4 line EXTI_InitStructure.EXTI_Line = EXTI_Line4; EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt; EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling; EXTI_InitStructure.EXTI_LineCmd = ENABLE; EXTI_Init( EXTI_InitStructure); // Configure EXTI5 line EXTI_InitStructure.EXTI_Line = EXTI_Line5; EXTI_Init( EXTI_InitStructure); // Enable and set EXTI4-15 Interrupt NVIC_InitStructure.NVIC_IRQChannel = EXTI4_15_IRQn; NVIC_InitStructure.NVIC_IRQChannelPriority = 0x10; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init( NVIC_InitStructure); //Sys_Enter_Standby(); } 0 本主题由 Harmony技术专家于 2024-5-8 16:59 审核通过

答案对人有帮助，有参考价值 0 降电流除了进入低功耗模式外，还要注意晶振频率，很多功耗来源于时钟频率导致的静态功耗
