1. Introduction The HMI (Human-Machine Interface) is increasingly used in industrial automation systems and devices due to its small size, high performance, and strong real-time capabilities. It features various displays such as letters, Chinese characters, graphics, and images, with a simple and user-friendly interface. Equipped with long-lasting membrane button keyboards, it is easy to operate. … Read more
The default integer constant operations in the C51 compiler may lead to overflow errors. To avoid potential calculation errors, the data type of large integers should be specified. Keil C51 is a compiler compatible with ANSI C. The ANSI C standard specifies that the default data types for decimal integer constants are one of int, … Read more
Recently, I have encountered the issue of Chinese garbled text in the compiler. Although it does not affect the execution of the program, it always feels awkward to see a bunch of garbled text. I have a bit of OCD and always want to fix it! The reason for this problem is that everyone uses … Read more
An error occurred: FATAL ERROR L210: I/O ERROR ON INPUT FILE: EXCEPTION 0021H: PATH OR FILE NOT FOUND. Later I found out that it was due to insufficient MCU memory. After some investigation, I discovered that my KEIL was not cracked, which prevented compilation of programs larger than 2K. After cracking KEIL 2 again, loading … Read more
