Follow+Star Public Account, don’t miss wonderful content Source | Renesas Embedded Encyclopedia UART is one of the most common communication methods in embedded development, thus making it a necessary peripheral for many projects. The MCU UART (Universal Asynchronous Receiver-Transmitter) achieving sleep wake-up functionality typically involves low power design, interrupt mechanisms, and UART configuration. Below, we … Read more
Overview:The I2C communication interface is the most commonly used MCU peripheral in our daily applications. Initially, before the MCU had hardware I2C, I2C communication was achieved by simulating the I2C timing through GPIO ports. Later, with the introduction of hardware I2C peripheral interfaces in MCUs, the use of hardware I2C became commonplace. More importantly, it … Read more

Thirty years ago, a small machine the size of a room had computing power that is still inferior to the CPU in today’s smartphones. Surprisingly, there is a technology from 38 years ago that is still widely used in computers … Read more
/*** Direct Hit to the Essence ***/ 1) A certain time delay is required when powering up the entire chip The main reason is that during the power-up process, the power supply is not stable enough, which may interfere with the internal initialization of the chip, causing abnormal operation of peripheral devices; at the same … Read more

In engineering, there are many issues related to sleep and wake-up. In the vehicle’s network topology, many nodes have similar problems. For example: Reusing SPI leads to communication loss, nodes cannot sleep, node startup time exceeds the required time, nodes occasionally cannot wake up, and so on. These engineering issues are sometimes viewed as network … Read more
