►
www.ee.ntou.edu.tw
Basic Supply Voltage is 5V, there are 3 ways to supply power :
–
–
–
–
ICE_USB : mini USB connector for on-board NuLink ICE
CON5: DC supply connector
POWER1: VCC & GND pins (beside CON5)
J3: mini USB of NUC140 device
►
Learning Board provide +5V, +3.3V power on the lower-right side
3VVC1 = 3.3V, 5VCC1 = 5V, VCC = 5V, GND1 = GND
max. current is depending on the power supply source, if connecting
to PC USB port, its current is about 500mA
Note: During the excerise/experiement, PC may cut off power of USB
port if short circuit happens. Please reset the PC to resume the power
supply from USB port.

www.ee.ntou.edu.tw
►
NuMicro MCU Learning Board has 5 group of GPIO pin
: GPIOA, GPIOB, GPIOC, GPIOD, GPIOE
►
They are named GPA, GPB, GPC, GPD, GPE
– Sample code use E_GPA, E_GPB, E_GPC, E_GPD, E_GPE as its
defined port name
►
GPIO pins are allocated at the pins at the lower part of
the learning board : J4, J5, J6, J7, J8
►
You can jump wire to external device with these pins
GPIO group A, B

NuLink ICE used with PC
Department of Electrical Engineering,
National Taiwan Ocean University
www.ee.ntou.edu.tw
NuLink ICE is built-in on board with miniUSB connector
SDK Installation
Department of Electrical Engineering,
National Taiwan Ocean University
►
►
www.ee.ntou.edu.tw
Before connecting NuMicro MCU Learning Board to PC, you will need
install the following :
– Keil/IAR Tools (for program editting, compiling, debugging)
– NuLink device driver (NuLink USB driver for PC)
– Nuvoton BSP (Learning board sample codes from Nuvoton)
After the above installation, you can connect the miniUSB port of
NuLink (upper side of the NUC140 learning board) , and
– Build (compile) your sample code into binary file, and Download (burn)
thru NuLink to NUC140 on the learning board
– Then press Reset button to execute the new code inside NUC140
– Or you can unplug and reconnect USB cable which is also reset the entire
system to restart with new code
Nuvoton provide NuMicro SDK CDROM with free software tools & sample codes,
you can also download the latest driver and sample code from www.nuvoton.com
Quick New Project Creation (Keil example)
Department of Electrical Engineering,
National Taiwan Ocean University
www.ee.ntou.edu.tw
►
Create a new project folder Smpl_newproj
► Copy 3 files from old sample project
–
–
–
►
Rename 3 files into new sample name
–
–
–
►
smpl_old.uvproj
smpl_old.uvopt
smpl_old.c
smpl_new.uvproj
smpl_new.uvopt
smpl_new.c
Change to new project folder, double click on smpl_new.uvproj
–
–
–
–
–
the error message show up is smpl_old.c is missing (because we rename it to smpl_new.c)
Move cursor to the left side of the Keil window
Point to smpl_old.c & right mouse click, a menu will show up, please choose “remove from the
project”
Point cursor to Source Files, and right mouse click, a file window will show up, then select
smpl_new.c to add into the project Source Files
Point cursor to window left top corner, and revise the project name from smpl_old to smpl_new
Build and Download Binary Code into MCU
Department of Electrical Engineering,
National Taiwan Ocean University
►
At Keil project window, top menu select Flash , select Configure Flash Tools…
–
–
–
–
–
–
►
it will show up a configuration window : Options for Target ‘Smpl_new’
select Output, and rename Smpl_old to Smpl_new
select Target to confirm the correct Target Device is Nuvoton NUC140VE3AN (learning
board MCU)
select Debug to use Nu-Link Debugger
select Utilities to use Target Driver Nu-Link Debugger
select OK on the bottom of the configuration window
To build project (compile C code into binary code)
–
–
–
►
www.ee.ntou.edu.tw
Keil command menu，press F7 / Build Target , or select Project and select Build Target
If shown 0 error on the console (the bottom of project window), the binary code will be
generated, Else you need to debug the error
Click on the error message in the console, it will takes you to the line of error code
To download binary code into MCU chip
–
Press Download, or menu select Flash and select Download
Setup for using printf function
Department of Electrical Engineering,
National Taiwan Ocean University
►
www.ee.ntou.edu.tw
NuMicro has a printf function of C for MCU, the following steps will direct printf
output to UART0 :
Step 1. startup_NUC1xx.s line #10 FALSE changed to TRUE
SEMIHOSTED
SETL {TRUE}
Step 2. retarget.c around line #20 to add
#define DEBUG_ENABLE_SEMIHOST
(also retarget.c need to be added to Library Files of the current project, retarget.c can be
found in src/NUC1xx-LB_002/ )
Step 3. add printf statement into the C code
printf will print message to UART0, so it will slow down the program due to using UART0
to PC, so we recommend to remove printf statement after debug is done
Step 4. Build project and Download code into MCU
Step 5. Open Debugger Session of Keil, and open UART1 of view window
Step 6. Run (F5)
