Each emulator ID is not duplicated, it can acce multiple emulators at the same time. Nu-Link supports ICP (In-Circuit Programming) Engineering Based on SWD signal interface. Users can use Nuvoton NuMicro ICP Programming Tool development software to update chip firmware, and also apply to chip firmware production. And support third party development tools, such as Keil RVMDK, IAR EWARM and CooCox CoIDE. Nu-Link is a basic Debugger and programmer (Programmer) with functions of adjustment, online programming and offline programming. A USB port is linked to a computer host, a group of state indicator lights (Status LED), an offline programming button (Offline Programming Button), a SWD port link target chip for adjustment and programming, and the SWD port voltage level is fixed to 5.0V. Nu-Link is not only a simulator, but also an online and offline downloader. It is a 3 to 1 tool for R & D to ma production. Support KEIL, IAR, CoIDE, and other IDE tools Flash breakpoint, regardle of whether the code is in RAM or ROM, you can use breakpoints without restrictions, and are not limited by the number of breakpoints in Cortex chips. Support serial debugging based on ARM Cortex-M0 device (SWD). Support memory read and write, terminal simulation and serial debug output during program running. Nu-Link also supports on-chip program upgrade and update (In-Circuit Program function), for the development of ma production to achieve integrated, simple operation. USB HID device is not drive, plug and play Firmware programs support the automatic update of official software, Support WINXP, WIN7 and other 32 - bit, 64 - bit operating system Support the whole series of MCU in the new Tang Dynasty The interface is defined as the Official Standard Edition: VCC can choose 5V or 3.3V from a jumper
