▼Click the card below to follow the public account ▼ Since we started working with microcontrollers, we have known about a software called KEIL. When developing microcontrollers, we use C language or assembly language. We know that neither of these languages can be directly loaded into the microcontroller. Regardless of whether it executes or not, … Read more

This article will introduce personal debugging experiences. This section is divided into the following parts: 1) Virtual Serial Port … Read more
Keil Keil consists of µVision + Development Tool Kit. µVision is the shell, while the development tool kit is the core, combined to form four complete software products. For example, keil5 (Keil µVision5) includes four products: • Keil for Arm • Keil for C51 • Keil for C251 • Keil for C166 Similarly, Keil4, Keil3, … Read more
Analysis of Assembly Errors in Microcontroller Assembly Language Currently, there are two different standards for the instruction format of assembly language: Assembly languages on Windows generally follow Intel-style syntax, such as MASM and NASM; whereas assembly languages on Unix/Linux generally follow AT&T-style syntax; 1. General Format of Assembly Language Statements [Name[:]] Opcode [First Operand][,Second Operand] … Read more
