1 Overview
The NuTiny-SDK-NUC472 is a specific development tool for NuMicro™ NUC472 series.
User can use NuTiny-SDK-NUC472 to develop and verify the application program
easily. The NuTiny-SDK-NUC472 includes two parts: NuTiny-EVB-NUC472 and Nu-
Link-Me. The NuTiny-EVB-NUC472 is the evaluation board and Nu-Link-Me is its
Debug Adaptor. Therefore, user does not need other additional ICE or debug
equipment.
2 Introduction to NuTiny-SDK-NUC472
The NuTiny-SDK-NUC472 uses the NUC472HI8AE as the target microcontroller. Figure
2-1 shows the NuTiny-SDK-NUC472 for NUC472 series, in which the left portion is
called NuTiny-EVB-NUC472 and the right portion is called Nu-Link-Me.
The NuTiny-EVB-NUC472 is similar to other development boards. User can use it to
develop and verify applications to emulate the real behavior. The on-board chip covers
NUC472 series features. The NuTiny-EVB-NUC472 can be a real system controller to
design user’s target systems.
The Nu-Link-Me is a Debug Adaptor, which 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 the Nu-Link-Me Debug Adaptor with IAR or
Keil, please refer to the “Nuvoton NuMicro™ IAR ICE Driver User Manual or “Nuvoton
NuMicro™ Keil ICE Driver User Manual” for details. The two documents will be stored
in the local hard disk when each driver is installed.
