01 Program Structure Optimization 1. Program Writing Structure Although the writing format does not affect the quality of the generated code, certain writing rules should still be followed during actual programming. A clearly written program is beneficial for future maintenance. When writing programs, especially for statements like While, for, do…while, if…else, switch…case, and their nested … Read more
Porting C to the MCU (commonly known as microcontroller) 8051 began in the late 1980s. Objectively speaking, there are many challenges in porting C to the 8051 MCU. For example: · The 8051’s non-Von Neumann architecture (separate program and data memory spaces), along with additional bit-addressable memory space on the chip; · The on-chip data and … Read more
The microcontroller is the core component of embedded systems, and circuits using microcontrollers are much more complex. However, when modifying and adding new features, circuits with microcontrollers are easier to implement, which is why electronic devices use microcontrollers. So, what are the challenges to pay attention to in the design of microcontroller circuits? 1. Selection … Read more
