Currently, using Keil C51 and Proteus for microcontroller system development has become the first choice for many microcontroller enthusiasts. The combination of Keil C51 and Proteus allows for software design and hardware simulation debugging of microcontroller systems, which can greatly shorten the development cycle and reduce development and debugging costs. Once the simulation debugging is … Read more
In-depth analysis of Keil C51 bus peripheral operation issues. 1 Problem Review and Analysis In actual work, encountering repeated consecutive reads of the same port, the Keil C51 compiler did not achieve the expected results. Analyzing the assembly program generated by the C compiler found that the second read statement of the same port was … Read more
In the debugging state of Keil C, how can we observe the operating status of various internal and external peripherals? How can we modify their settings? Answer: In debugging state, click on different peripheral options under the Peripherals menu to display or hide the corresponding observation windows. For example, to display the Timer 0 window, … Read more
1. Analysis of Reasons for Assembly Software Failure: This article uses the macro assembler A51 from the Keil C51 software package as the compiler. When writing assembly language for microcontrollers, it is important to pay attention to specific syntax. For detailed information, please refer to relevant reference books. Syntax errors can lead to assembly failures. … Read more
In microcontroller development, many engineers choose assembly language for low-level programming to directly control hardware and execute commands efficiently. However, since assembly language interacts directly with hardware, it is easy to make mistakes. This article summarizes common errors in microcontroller assembly language based on the Keil C51 assembler environment, hoping to assist fellow engineers. 1. … Read more
