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

Why Use C Language for Microcontrollers?

by
Why Use C Language for Microcontrollers?

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
