(3) Double click dpinst_ia64.exe for 64-bit Windows installation or dpinst_x86 for 32-bit
Windows installation.
(4) To test the functionality, connect the (CN3) jumper and use PC terminal tool to test the
UART loop test.
3.4 Build up the first program on DELTA DFCE-NNN40
(1) After you login the mbed, click the new program button. Then choice one of the example
program, the project will be generated from mbed.
(2) Click the compile button directly; the image file will be generated from mbed
(3) The image file can be saved to USB drive of DELTA DFCE-NNN40 directly. Or download to
your local storage and use drag-n-drop to USB drive to load firmware.

4.2 Kit PIN OUT
DELTA DFCE-NNN40 has a default profile pin out. The board has reserved SPI, I2C, ADC,
UART and GPIO pin to access. The following is the detail of description for pin out.
1.8V pin
The voltage of power supply for BLE module is 1.8V. All BT GPIO (P4~P29), are connected
to BLE SoC. It is notice that the voltage should be 1.8V.
3.6V pin
There are pins are passed through level shift to convert from 1.8V to 3.6V. Those are
SCL_3V6, SDA_3V6, STLK_TX, and STLK_RX.
RF switch pin
To switch RF antenna to BLE or Wi-Fi, it is controlled by gpio pin SWIO, P19.
Use j-link to load image to BLE module directly
It is able to use j-link to load image to BLE module directly. The R124 and R125 should be
removed. The SWDIO and SWDCLK is then accessible on CN7 pin 25, 23 respectively.
ADC function
P04, P05, P06, P26, P27 could be to ADC function. It is notice that only P06 could be
configure to reference ADC voltage (ADC/LPCOMP reference input 0 and in input 1). Only
one of the modules can be enabled at the same time.

4.7 Measuring Current
The current drawn by the DFCE-NNN40-DTxR module can be monitored on the DELTA
DFCEM-NNN40 mbed kit. To measure the current, you must first prepare the board by
removing the 0Ω on R127and R128. To measure the current of BLE chip, please connect
current meter series to 1V8 and BLE_1V8_IN pin on CN7; while the current of Wi-Fi chip
measurement, please connect current meter series to 3V6 and WIFI_3V6_IN pin on CN7.
