Setup
Mounting the mbed Board
The mbed board should be mounted on the mX-BaseBoard with a particular alignment.
Note: Improper mounting of the mbed board on mX-BaseBoard may damage the mbed board and /
the mX-BaseBoard.
The GND pin on mbed board should be aligned with the pin 1 of P9 female header on BaseBoard.
Refer to the marking as shown in the image below.

The mbed NXP LPC1768 board comes with a USB boot loader. Refer to the mbed device
documentation for usage. Use the binaries from NGX Technologies to validate the mX-BaseBoard.
Validating the mX-BaseBoard
Download the binaries as .zip form here. For source code refer to README.txt in .zip file.
Ethernet
Copy the mX_Ethernet_LPC1768.bin to mbed board. Connect the Ethernet cable to the
board and reset the board. (It is assumed you are connecting it to router with internet connection)
The firmware will look for a particular site and display the time. See the screen-shot below.
Audio
Copy the mX_audio_LPC1768.bin to mbed board. For this you need a SD card with FAT
file system and set up a terminal for the USB com port. Copy the file forest.wav (available in the
directory with the binaries) to the SD card. Insert the SD card and reset the board. Connect speaker
or headphones to hear sound.
SD card
Copy the mX_SD_card_LPC1768.bin file to mbed board. For this test you need a SD card
with FAT file system and set up a terminal for the USB com port. Insert SD card and reset the
board. Once in the terminal you see “Hello World! Goodbye World! ”, remove the SD card and read
its content. It should contain a file named sdtest.txt --> “Hello fun SD Card World!”. If the SD card
is not there “Could not open file for write” will be displayed in the terminal.
I2C
Copy the mX_I2C_24LCxx_LPC1768.bin to the mbed board and reset the board. In the

terminal a menu will be displayed. Choose “a” to write and read a string. Refer image below.
USB
Copy the mX_USB_HID_LPC1768.bin to the mbed board and reset the board. Connect a
USB cable to connector J7 with PC. In the device manager in Windows it should be HID-compliant
mouse detected.
UART0
Copy the mX_UART0_LPC1768.bin to the mbed board and reset the board. Connect the
serial cable to J4 and PC serial port. Open a terminal and press 'a'. It will reply with “Hello World” .

If any other key is pressed it displays “Press 'a'”.
UART1
Copy the mX_UART1_LPC1768.bin to the mbed board and reset the board. Connect the
serial cable to J5 and PC serial port. Open a terminal and press 'b'. It will reply with “Hello World” .
If any other key is pressed it displays “Press 'b'”
Buzzer
Copy the mX_buzzer_LPC1768.bin file to mbed board and reset the board. A tone is heard
on the buzzer. The jumper JP1 should be inserted.
Ext Int
Copy the mX_ext_int_LPC1768.bin file to mbed board and reset the board. The LED1
keeps blinking. When the button SW6 is pressed the LED 4 glows.
ADC
Copy the mX_ADC_LPC1768.bin file to mbed board and reset the board. Changing the
preset R14 the LED 1, 2, 3 and 4 glow in increasing sequence.
LCD
Note: Using LCD some o the functions on the stamp (multiplexed pins) will not be available,
namely CAN, I2C and some pins of PWM.
For the LCD to work you need to make some connections using burg wires. Copy the
mX_LCD_LPC1768.bin mbed board and reset the board. Refer to table below.
