1Overview
NuTiny-SDK-NUC240 is the specific development tool for NuMicro NUC240 series. Users can use NuTiny-SDK-
NUC240 to develop and verify the application program easily.
NuTiny-SDK-NUC240 includes two portions. One is NuTiny-EVB-NUC240 and the other is Nu-Link-Me. NuTiny-EVB-
NUC240 is the evaluation board and Nu-Link-Me is its Debug Adaptor. Thus, users do not need other additional ICE or
debug equipments.
2NuTiny-SDK-NUC240 Introduction
NuTiny-SDK-NUC240 uses the NUC240VE3AE as the target microcontroller. Figure 2-1 is NuTiny-SDK-NUC240 for
NUC240 series, the left portion is called NuTiny-EVB-NUC240 and the right portion is Debug Adaptor called Nu-Link-
Me.
NuTiny-EVB-NUC240 is similar to other development boards. Users can use it to develop and verify applications to
emulate the real behavior. The on board chip covers NUC240 series features. The NuTiny-EVB-NUC240 can be a real
system controller to design users’target systems.
Nu-Link-Me is a Debug Adaptor. The Nu-Link-Me Debug Adaptor connects your PC's USB port to your target
system (via Serial Wired Debug Port) and allows you to program and debug embedded programs on the target
hardware. To use Nu-Link-Me Debug adaptor with IAR or Keil, please refer to “Nuvoton NuMicro™IAR ICE driver
user manual “or Nuvoton NuMicro™Keil ICE driver user manual” in detail. These two documents will be stored in the
local hard disk when the user installs each driver.
