A traditional fuel vehicle requires about 500 to 600 chips, a mild hybrid vehicle requires about 1000 chips, and plug-in hybrid and pure electric vehicles require at least 2000 chips. This means that with the rapid development of smart electric vehicles, the demand for advanced process chips is increasing significantly, and the demand for traditional … Read more
Previously, when using STM32’s SPI to control many external chips, there was only one chip select for a single SPI peripheral. How can we achieve independent chip selection for one master and multiple slaves? SPI Bus Topology Generally, the SPI bus is connected as shown in the figure below, with one master and multiple slaves. … Read more

The article about the module is about to begin, and I plan to write a series of beginner and intermediate tutorials on modules and STM32 in the future. Generally speaking, manufacturers of the ESP8266 module will periodically upgrade the firmware inside the module and release it, so we must also master the method of upgrading … Read more
Embedded systems are ubiquitous. Almost every electrical device you interact with is more complex than a simple light switch; it contains a digital processor that reads input data from its environment, executes computational algorithms, and generates some output to interact with the environment. From waking up in the morning (responding to alarms from digital devices) … Read more
