Nuvoton Toolchain Series – Introduction
Before using the Nuvoton development board, it is essential to know which software Nuvoton offers to assist developers’ work. The following is an overview of the Nuvoton development software.
Nuvoton’s development software is applicable from the stage of engineering development to mass production. It is mainly classified into the following four categories:
- Category 1: software development environment and related drivers
- Category 2: complete original code and example code for related functions
- Category 3: software for development and testing
- Category 4: programmer exclusive for debugging and mass production
The following is a detailed breakdown of the four software categories:
1. IDE & Nu-Link Driver
a. IDE: Nuvoton offers three software packages for the IDE development environment: Keil MDK, IAR EW8051, and the company’s own NuEclipse. The table below provides a more complete description.
