Features: Each-ID is not duplicated, it can access multiple emulators at the same time-. 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 for Keil- RVMDK, IAR- EWARM and CooCox CoIDE. 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 simulator and an online and offline downloader. Support KEIL-, IAR-, CoIDE, and other IDE- tools. Flash breakpoint, regardless 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, simple operation, no drive needed, plug- and use, Firmware programs support the automatic update of official software, Support for WINXP, WIN7 and other 32 - bit, 64 - bit operating- system. The interface- is defined as the Official Standard Edition: VCC- can choose 5V or 3.3V from a jumper-.
