STM32的低功耗模式大体分为三种,睡眠模式、停机模式、待机模式。 细分有Sleep mode(睡眠模式)、Low-power run mode(低功耗运行模式)、Low-power sleep mode(低功耗睡眠模式)、Stop mode with RTC(带有RTC的停止模式)、Stop mode without RTC(不带RTC的停止模式)、Standby mode with RTC(带有RTC的旁路模式)、Stan...

STM32 低功耗选型分享: ✖ 低功耗MCU选型要点摘要有时为了一款低功耗产品而绞尽脑汁,产品的低功耗实现往往在于主控MCU的选择。低功耗MCU选型要点powerDown时有极低的电流功耗,小于1uA。 极低功耗模式下能实现定时唤醒。该项在做一些 算一挂 2021-11-04 06:32:49 ...
首先要开启tickless mode机制,还是freeRTOSConfig.h中修改 configUSE_TICKLESS_IDLE。 #define configUSE_TICKLESS_IDLE 1 1. extern void PreSleepProcessing(uint32_t ulExpectedIdleTime); extern void PostSleepProcessing(uint32_t ulExpectedIdleTime); ...
STM32 ARM MCU are proposing different low power mode for saving energy when running IoT on battery. Some basic example of low power are delivered with the SDK as part of CubeMx solution but these example are not really complete, not well documented and in my point of view difficult to use...
目前尝试用裸机例程中的休眠函数,仅LowPower_Shutdown(0); 可以正常睡眠并且成功唤醒。其他方式均不能唤醒。但此方式唤醒后task会 zmyecho 2022-08-01 06:19:59 ECU系统休眠后通过诊断报文唤醒ECU且唤醒网络 ECU系统休眠后TJA1043的INH脚处于floating高阻态,系统休眠后通过硬件外部电路下拉到低电平状态/Low-level...

My main concern is that all 1.2V domain clocks are off in the Stop mode. The only working programmable wake-up source is RTC. I guess that means SYSTICK is not increased during the low power mode. Have anybody considered implementing the low power mode for STM32FX family and how to ove...
