IntroductionmX-BaseBoard is a new addition to the BlueBoard line from NGX Technologies. This board

is intended to extend the functionality of the LPCXPRESSO LPC1343 board. The board is a stamp for LPC 1343. mX-BaseBoard can be used to extend the features of the stamp by providing connectors and interface to various peripherals of the stamp and provide power to the peripheral interface.

Features• 2x16 with contrast control & back light

• SD Card connector

• USB

• Power Jack

• Power Switch

• Reset Button

• ISP Button

• External interrupt Button

• Buzzer

• Audio Jack

• PS/2

• Serial Connector 0

• Preset for ADC

• On board EEPROM

Getting StartedBefore starting you would need the following things handy and ready. For compiling and

running programs refer to LPCXpresso Getting started with NXP LPCXpresso.

RequirementThe requirement is put in two sections.

Hardware

• Power adapter – rating 7.5 V, 1 AMP

• SD card • USB mini cable • Serial cable• PS/2 Keyboard

Software

• PC with Windows OS • Use HyperTerminal as terminal software• LPCXPRESSO LPC1343 workspace from NGX Technologies

Setup

Mounting the Xpresso Board

The LPCXPRESSO LPC 1343 board should be mounted on the mX-BaseBoard with a particular alignment.

Note: Improper mounting of the Xpresso board on mX-BaseBoard may damage the Xpresso board and / the mX-BaseBoard.

The GND pin on Xpresso board should be aligned with the pin 1 of P9 female header on BaseBoard. Refer to the marking as shown in the image below.




Validating the mX-BaseBoardDownload the workspace as .zip form here.

Note: You need to flash the Xpresso board with the required firmware according to the functionality.

Blink

NGX_mX_1343_blink – This blinks the LED2 on the Xpresso board.

LCD

NGX_mX_1343_LCD – Reset the board and “NGX Technologies” is displayed on the LCD screen.

Audio

– work in progress

SD card

NGX_mX_1343_SD_card – Insert a SD card with FAT16 file system and reset the board. On the LCD it should display “SD-CARD Test PASS”. Remove the card and reset the board, it displays “SD-CARD Test FAIL”.

I2C

NGX_mX_1343_I2C – On the LCD it displays “I2C TEST PASS”. Connected to the I2C lines is an EEPROM device. The program writes and reads back a piece of data to test.

USB

NGX_mX_1343_USB_HID – Reset the board. Connect a USB cable to connector J7 with PC. In the device manager in Windows it should be “HID-compliant device” as shown below.

UART0

NGX_mX_1343_UART – Connect the serial cable to J4 and PC serial port. Open a serial terminal with 115200 baud, 8N1. The typed characters are echoed to the serial terminal.

Buzzer

NGX_mX_1343_buzzer – Reset the board and a tone is heard on the buzzer. The jumper JP1 should be inserted.

Ext Int

NGX_mX_1343_Ext_Int – Reset the board and the buzzer toggles between on and off when the button SW6 is pressed.

ADC

NGX_mX_1343_ADC – Reset the board and vary the pot R14. The change in value is represented as shown below.

PS/2

NGX_mX_1343_kbd – Connect a PS/2 keyboard and reset the board. Type in the keys on the keyboard and the corresponding characters are displayed on the LCD.

ISP ProgrammingOn the mX BaseBoard press and hold the ISP switch (SW5), then press and release reset

switch (SW4), then release ISP switch (SW5). This put the micro-controller in ISP programming mode. Using flash magic flash the device. Refer below for settings in screen shots.

Start the Flash Magic tool. Step 1: As in the screen shot select the device as “LPC 1114/301”. Select the com port to which the device is connected. Here it is “COM 1”. Set the baud rate to “38400”. Interface to “None (ISP)”. Set Oscillator MHz to “16”.Step 2: Tick mark “Erase all Flash+Code Rd Prot”




Step 3: Select the path for the .hex file.

Step 4: Tick mark “Verify after programming”

Before starting to program in the Options → Communications tab

Tick mark “High Speed Communications”

Options → Hardware config

Tick mark “Use DTR and RTS to control RST and ISP pin”.




Step 5: After this start the programming.

Compiling the WorkspaceDownload the workspace form here and unzip it. Start the LPCXpresso and point to the

directory path where the work space is unzipped.

In Xpresso IDE right click on the NGX_mX_1343_blink project and it can build, clean close the project.

After building the project initiate debug to download the program to the target. Press F8 to resume the program execution. This blinks the LED 2 on Xpresso board.

USB Boot loaderThe Xpresso board can be programmed using USB interface. Flash the USB boot loader

firmware using any of the above method. The project space is NGX_mX_1343_USB_HID. Connect a USB cable from the base board (J7) to the PC

After reset it would be detected as an HID device in Windows Device manager.

On the base board press and hold switch (SW5), then press reset switch (SW4). Release the reset switch (SW4) and then SW5. The device will be detected as a external storage device.

A file named firmware.bin is already present. Delete this file and copy the led blink file NGX_mX_1343_blink.bin. Reset the board. The LED2 should blink.
