NuTiny-SDK-NUC140 uses the NUC140VE3AN as the target microcontroller. Figure 2-1 is NuTiny-SDK-NUC140 for NUC140 series, the left portion is called NuTiny-EVB-NUC140 and the right portion is Debug Adaptor called Nu-Link-Me.
NuTiny-EVB-NUC140 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 NUC140 series features. The NuTiny-EVB-NUC140 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.

NUC130/140 CAN演示板
A Controller-Area-Network (CAN)-Bus system enables device communication in harsh environments, found in industrial automation, military and automotive applications. As a multi-master system, each device (node) can obtain bus access through its unique priority code (address) and broadcasts messages to all bus participants simultaneously. The Nuvoton NuMicro Family NUC140/NUC130 series chips had offered the robustness of the CAN architecture which is licensed from Bosch.

This CAN-Bus demonstration kit simulates industrial and automotive control environments.
A System Monitor Node (Node 0 ) This node can be connected to an external PC through a USB interface. The PC/laptop controls the speed rate and shows the real time speed on the screen
A System Monitor Node (Node1) controls the motor speed up/down function
A System Monitor Node (Node2) controls the motor speed up/down function
A Motor Node (Node3) controls speed or start/stop of a stepper motor
