NUTINY-SDK-N76E885 INTRODUCTION
NuTiny-SDK-N76E885 uses the N76E885AT28 as the target microcontroller. Figure 2-1 is
NuTiny-SDK-N76E885 for the N76E885 series, the left portion is called NuTiny-EVB-N76E885
and the right portion is Debug Adaptor called Nu-Link-Me.
NuTiny-EVB-N76E885 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 N76E885 series
features. The NuTiny-EVB-N76E885 can be a real system controller to design user
’s target
systems.
Nu-Link-Me is a Debug Adaptor. The Nu-Link-Me Debug Adaptor connects your PC's USB port to
the user
’s target system (via Serial Wired Debug Port) and allows user to program and debug
embedded programs on the target hardware. To use Nu-Link-Me Debug adaptor with Keil, please
refer to
“Nuvoton Nu-Link debug adapter user manual” in detail. This document will be stored in
the local hard disk when user installs each driver. Nu-Link-Me also supports virtual COM port
function. User can use Nu-Link-Me as a USB to UART virtual COM port, which connects to on-
board N76E885AT28 UART0.

Virtual COM Port Switch Description
2.1
The switch in Nu-Link-Me, SW3, determines that the virtual COM port function is enabled or
disabled. When user turns on all of the positions of switch, the virtual COM port function will be
enabled. By using virtual COM port function, user can access the USB device in the same way as
it would access a standard COM port to N76E885AT28 UART0. To use this function, user needs
to install
“VCOM Driver” at first. User can get “VCOM Driver” from NuMicroDVD
www.nuvoton.com\NuMicroDVD
in folder
“Software Utilities”.
