NuMicro ISP Tool

The NuMicro ISP Tool is an open-source utility for programming and configuring Nuvoton microcontrollers via In-System Programming (ISP). It supports multiple interfaces (USB HID, UART, SPI, I²C, RS485, CAN, LIN, Wi-Fi, BLE) and communicates with the ISP application running in LDROM on the target device.

Features

• Cross-interface ISP programming (USB HID, UART, SPI, I²C, RS485, CAN, etc.)
• Supports Nu-Link2-Pro/Nu-Link3-Pro ISP-Bridge mode
• GUI for easy device configuration and programming
• Chip database for automatic device recognition
• Extensible with new chips and protocols
