NUMAKER-EMWIN-NK-N9H26 USER MANUAL
1 OVERVIEW
The NuMaker-emWin-NK-N9H26 is the specific development tool for N9H26 series. Users can
use NuMaker-emWin-NK-N9H26 to develop and verify the application program easily.
The NuMaker-emWin-NK-N9H26 includes two portions. One is NuMaker-emWin-NK-N9H26 main
board and the other is NuMaker-TFT-LCD5 LCM display board. The NuMaker-emWin-NK-N9H26
is the N9H26 series evaluation board and NuMaker-TFT-LCD5 is support Pixel Format
480(RGB)/272 display Adaptor.
The N9H26 is built on the ARM926EJ-S CPU core and is integrated with USB2.0 HS Host/Device,
NAND/eMMC/SD/SDIO/SPI host controller, video codec (H.264), Jpeg codec, 32-channel SPU
(Sound Processing Unit), ADC, DAC and AAC accelerator for saving the BOM cost in various
kinds of application needs to the best choice.

2 NUMAKER-EMWIN-NK-N9H26 INTRODUCTION
The NuMaker-emWin-NK-N9H26 uses the ARM926EJ-S CPU core as the target micrprocessor.
The NuMaker-emWin-NK-N9H26 is similar to other development boards. Users can use it to
develop and verify applications to emulate the real behavior. The NuMaker-emWin-NK-N9H26
can be a real system controller to design users’ target systems, supports USB2.0 Host/Device
high speed interface, microphone, audio headphone out, audio amplifier, speaker out, JTAG
interface, SPI Flash and RS-232 interface.
NuMaker-TFT-LCD5 is a LCM display with touch panel adaptor, it is supporting Pixel Format
480(RGB)/272 resolutions.
The NuMaker-emWin-NK-N9H26 development connects JTAG port to your target system (via
JTAG adaptor tool) and allows you to program and debug embedded programs on the target
hardware.

The NuMaker-emWin-NK-N9H26 is the specific development tool for NuMaker-emWin-NK-N9H26
series. Users can use NuMaker-emWin-NK-N9H26 to develop and verify the application program
easily.
The NuMaker-emWin-NK-N9H26 includes two portions. One is NuMaker-emWin-NK-N9H26 and
the other is NuMaker-TFT-LCD5. The NuMaker-emWin-NK-N9H26 is the evaluation board and
NuMaker-TFT-LCD5 is its Debug Adaptor. Thus, users do not need other additional ICE or debug
equipment.
