NUTINY-SDK-NUC240 USER MANUAL

1 OVERVIEW

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.

NUTINY-SDK-NUC240 USER MANUAL

2 NUTINY-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. The Nu-Link-Me V3.0 also supports VCOM function,

which gives users more flexibility when debug. 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. To use Nu-Link-Me 3.0 VCOM function, please refer to Chapter 5.

SW3: VCOM function enable for NuTiny-SDK-NUC240. Switch SW3 on before power on to

enable VCOM function. SW3 connects pin 32(PB.0/RXD) and pin 33(PB.1/TXD) in NuTiny-

EVB-NUC240 with pin 22(PB.1/TXD) and pin 21(PB.0/RXD) in Nuvoton ICE adaptor (Nu-

Link-Me V3.0). SW3 connects pin 30(VCOM) in Nuvoton ICE adaptor (Nu-Link-Me V3.0) to

GND to enable VCOM function.
