stm32—PWR power control (sleep mode\stop mode\standby mode)
Graphic and text overview: !!!!!!!!!Attention!!!!!!!!! Every time you use the __WFI() instruction or the __WFE() instruction to program and download, if you need to re-download other programs, you need to exit the sleep mode. The download operation at this time is: press and hold the reset button without letting go, click download program, and then […]

Kotlin concurrency without sleep: an in-depth comparison of delay() and sleep()
This article is translated from: https://blog.shreyaspatil.dev/sleepless-concurrency-delay-vs-threadsleep There is no doubt that Coroutine in the Kotlin language has greatly helped developers handle asynchronous programming more easily. The many efficient APIs encapsulated in this feature can ensure that developers spend less effort to complete concurrent tasks. Generally speaking, it is enough for developers to understand how to […]

Energy-saving Sleep Awake Awareness (EESAA) intelligent routing protocol for WSN (Matlab code implementation)
Content introduction With the rapid development of the Internet of Things (IoT), Wireless Sensor Networks (WSN) have become an important technology for connecting and collecting environmental data. However, WSN nodes usually cannot run for a long time due to energy constraints, so energy saving has become an important consideration in WSN design. In order to […]
