Data Storage Order in Modbus Protocol

The Modbus protocol specifies the use of big-endian byte order at the byte level. However, for data types larger than 16 bits (i.e., 2 bytes) such as 32-bit floating-point numbers and 32-bit integers, the protocol does not define the order of words, leading to different implementations by various device manufacturers. Here is a detailed explanation: … Read more

Why is the Range of Float in C Language 3.4E+38? Unveiling the Secrets of Floating Point 'Hidden Bit' and 'Golden Rule'

In learning C language, float (single precision floating point) and double (double precision floating point) are two unavoidable hurdles. Many students memorize their value ranges—such as float being approximately ±3.4E+38—but do not understand where this astronomical number comes from. Today’s lesson is an “elective content,” but it is highly valuable. We will dive into the … Read more

Which Operating System Should You Learn First for Embedded Development?

Many beginners focus on Linux and VxWorks, thinking that “the more complex the system, the more powerful it is,” which is completely the opposite. Embedded devices are different from our computers; some devices have only a few KB of memory (like smart door locks), while others need to run dozens of tasks simultaneously (like automotive … Read more
