Introduction: For embedded systems, if there is no RTOS running, the main function (main()) in program development needs to keep running indefinitely through some mechanism; it has no endpoint. If you want to exit the main function, what to do specifically is determined by the C language compiler used. Keywords: C51, main, program exit 01 … Read more

Many people who have learned STM32 share a common characteristic: they can only use some representative hardware features, such as AD conversion, and can only perform single conversions, while they do not know how to perform loop or multiple conversions. Then they have to refer to the chip manual, but the problem is that the … Read more

When assigning values to registers using the C language, bit manipulation methods of the C language are often required. Clearing a Specific Bit of a Register Assume a represents the register, which already has a value. If we want to clear a specific bit while keeping other bits unchanged, the code is as follows. // … Read more
Connected video devices are everywhere. From doorbells to cars, cheap image sensors from old phones are finding new life in connected devices. This marks a significant shift in how we create and consume devices. As a result, video is shifting from a core function of the Internet of Things (IoT) to a secondary attribute. These … Read more
