1. The big-endian mode
means that the high byte of the data is stored in the low address of the memory,
and the low byte of the data is stored in the high address of the memory.
This storage mode is a bit similar to treating the data as a string sequence:
the address increases from small to large, and the data is placed from high to low;
this is consistent with our reading habits.
For example,
declare a 32-bit variable
with high address 0-7 bits
|/ 8-15 bits |
/ 16-23 bits
and low address 24-31 bits.
2. The little-endian mode
means that the high byte of the data is stored in the high address of the memory,
and the low byte of the data is stored in the low address of the memory.
This storage mode effectively combines the high and low addresses with the weight of the data bits.
The high address part has a high weight, and the low address part has a low weight.
For example,
declare a 32-bit variable
with low address 0-7 bits
|/ 8-15 bits
|/ 16-23 bits
and high address 24-31 bits.
The storage mode of STM32 microcontroller is little endian mode

- Learn ARM development(16)There are many things to learn about ARM, and interrupts are definitely something that needs to be learned. Since the CPU introduced interrupts, it has truly entered the multi-tasking system and greatly improved work efficiency. ...
- Learn ARM development(17)Because all embedded systems use interrupts, how does my S3C44B0 interrupt the process? Then I need to understand the whole process. To understand it in depth, the best way is to write a program ...
- Learn ARM development(18)Last time, we have learned about the interrupt handling process of ARM and how to set the interrupt function. So, does it work like this? The answer is no. Because S3C44B0 has several registers that control ...
- Embedded system debugging simulation toolAfter the embedded hardware system is designed, it needs to be debugged. Whether it is hardware debugging, software debugging or program solidification, debugging simulation tools are needed. ...
- A small question that has been bothering me recently has finally been solved~~Recently, I have not been able to understand the concept of drivers very well. Sometimes I can get a feel for it by combining some USB examples written by others, but because the ARM system does not directly explain the pins like the microcontroller ...
