1 Introduction A year ago, I researched an embedded device and found its acoustic configuration logic quite intriguing, but later focused on vulnerability exploitation and did not delve deeper. Recently, while studying wireless communications like sub-GHz, Bluetooth, and RF, I became interested again in transmitting information via acoustic signals, which led to this article documenting … Read more
Improving code portability in embedded development can be approached from the following aspects: 1. Follow Standards and Specifications 1. Programming Language Standards Strictly adhere to C or C++ language standards, avoiding the use of compiler or platform-specific extensions. For example, avoid using non-standard compiler built-in functions to ensure that the code compiles correctly in different … Read more
Outputting debugging information is an essential debugging tool in embedded development. One characteristic of embedded development is that often there is no operating system or file system, making conventional methods of printing logs to files generally unsuitable. The most common method is to output UART logs through a serial port. For example, with the 51 … Read more
Recently, I encountered a problem with byte endian conversion in a protocol, so I lazily went online to check it out and came across a similar issue, learning a new term called butterfly swapping. The Problem Is As Follows The protocol requires that the low byte is on the left and the high byte is … Read more
