NuEclipse

What NuEclipse is

NuEclipse is Nuvoton’s development environment for creating, building, and debugging projects for NuMicro microcontrollers. Its NuMicro 8051 offering supports 64-bit Windows and Linux, while the ARM offering covers NuMicro Cortex-M projects and NuMicro Cortex-A bare-metal projects. Supported targets also include NuMicro 8-bit devices. The maker lists two IDE variants: NuEclipse (SDCC) for NuMicro 8-bit and NuEclipse (GCC) for NuMicro Cortex-M; each uses the Nu-Link debugger. Integrated debugging and flashing are included. The listed Windows and Linux ARM downloads are version V1.02.029, dated 2025-03-06. For Cortex-M work, Nuvoton also lists a NuMicro Cortex-M Pack for Visual Studio Code, with project building, programming, and debugging on Windows and Linux. Both NuEclipse plans are free. Nuvoton’s site links users to technical support, a technical community, a learning center, FAQs, and technical blogs. Nuvoton was founded in 2008 and is headquartered in Hsinchu, Taiwan. Its stated focus spans microcontroller/audio, cloud security, battery monitoring, component, and visual sensing ICs.

Who it suits

NuEclipse suits developers building projects for NuMicro 8-bit, Cortex-M, or Cortex-A bare-metal targets on Windows or Linux. Cortex-M developers who work in Visual Studio Code can also consider Nuvoton’s listed Cortex-M Pack.

Getting started

1. Open Nuvoton’s IDE and compiler page.
2. Choose NuEclipse (SDCC) for NuMicro 8-bit or NuEclipse (GCC) for NuMicro Cortex-M.
3. Use the Windows or Linux download for the relevant NuEclipse offering.
4. For Cortex-M work in Visual Studio Code, choose the NuMicro Cortex-M Pack.

Verdict

Choose NuEclipse for free project creation, building, debugging, and flashing across its listed NuMicro targets on Windows or Linux. Cortex-M users who prefer Visual Studio Code can use the separate pack; the listed IDE variants are divided between 8-bit SDCC and Cortex-M GCC targets.
