2.0 BLUEBOARD-LPC11U24/37 OVERVIEW
2.1 INTRODUCTION
The NGX BLUEBOARD-LPC11U24/37 is a compact and versatile evaluation platform for the NXP's
Cortex-M0-based MCU. NGX's evaluation platforms are generally not tied up to any particular
debugger or compiler/IDE. However it is not practical to test and ensure that the solution would work
out of box with all the available debuggers and compilers/IDE. As long as the compiler supports the
particular MCU and the debugger supports the standard debug interfaces like the SWD you can use this
platform with any tool. The board is supported by extensive sample examples allowing you to focus on
the application development.
2.2 Board Features
Following are the salient features of the board
 Dimensions: 110mm X 110mm
 Two layer PCB (FR-4 material)
 Power: DC 6.5V with power LED On-board linear regulators generate +3.3V/500mA and
+5V/500mA from power supply USB connector (as alternate power source)
 10 pin, 20 pin CORTEX debug connector for SWD (Serial Wire Debug)
 ISP, Wakeup, External Interrupt and reset switch
 12.0000 MHz crystal for MCU, 32Khz crystal for RTC
 Extension headers for all MCU pins
 RS232 connector, PS2 connector, Micro SD/MMC card connector, USB type-B mini connector
with link-LED
 64x128 parallel graphical LCD with Backlight control
 High accuracy external RTC connected on I2C bus
 RTC battery holder
 10K pot for ADC
Note: The BLUEBOARD-LPC11U24/37 has support for both 20 pin and 10 pin debug header. You don't
need to buy a 20pin to 10pin converter (board which costs 10-15 USD).

3.1 Introduction
The NGX BLUEBOARD-LPC11U24/37 is based on ARM Cortex-M0 microcontroller from NXP.
LPC11U24 offers 32-KB Flash memory (LPC11U37 offers 128-KB Flash memory), 4-KB on-chip
EEPROM data memory, 50-MHz operation, I2C controller with data rate of up to 1 Mbit/s, USB 2.0
full-speed device controller, and wide range of peripherals. Refer to the LPC11U24 and LPC11U37 data
sheet for complete device details.
BLUEBOARD-LPC11U24/37 microcontroller is factory-programmed with a quick start demo program.
The quick start program resides in the BLUEBOARD-LPC11U24/37 on-chip Flash memory and runs
each time power is applied, unless the quick start has been replaced with a user program.

NGX's Blueboard evaluation platforms ship with a factory-programmed test firmware that verifies the
Blueboard peripherals. It is highly recommended that you verify the board, before you start
programming. Also this exercise helps you get acclimatized with the board quickly.
To run the tests you will need the following:

Table.1
4.2 Powering the Board
The Blueboard requires DC supply of 6.5V or 7.5 V, 1A rating to power it up. Alternatively the board
could be powered through USB connector.
Note: The USB power can source only up to 500 mA of current. For applications having higher current
requirements we recommend to use an external power supply. Please note that the external adaptor is
not a part of standard delivery.
4.3 Verifying all the peripherals on Blueboard
The following section focusses on the verification of all the peripherals supported on the Blueboard. The
order of the tests is mentioned in the same manners as the flow of the test firmware. We highly
recommend that you follow the order of the test. The test firmware is designed in a manner that the user
needs to spend as minimum time as possible to verify all the peripherals.
Note: It is highly recommended that the user tests all the peripherals as soon as the board is received.
Power up the board and we are all set to verify the Blueboard peripherals. The order of the peripherals
that are verified by the firmware are as follows:
4.3.1 LEDs
Test setup and verification:
As soon as the BlueBoard is turned ON or reset; the test LEDs go ON & OFF for a couple of times, this
simple test validates the LEDs.
12
www.ngxtechnologies.com
Quick Start Guide: BlueBoard-LPC11U24/37
4.3.2 Buzzer
Test setup and verification:
When the board is turned ON or reset you will hear a beep after few seconds. This confirms the status of
the Buzzer.
4.3.3 Graphics LCD (GLCD)
Test setup and verification:
After the LEDs blink and buzzer test the next interface that the firmware validates is the GLCD. A
message “NGX TECHNOLOGIES” should be displayed on the GLCD.
Fig 8
4.3.4 RTC
Test setup and verification:
Next, the firmware validates the external RTC connected over I2C bus. The RTC value is read and
displayed on the LCD.
Note: You may place the battery (not part of standard deliverables) for the RTC to retain the time even
after power off.
4.3.5 Micro SD Card
Test setup and verification:
Insert the Micro SD card in the SD card holder (J2), the status of the SD card will be displayed on
GLCD. If the SD card is inserted properly “SD card detected” is displayed on GLCD else it displays
“SD card missing”.
NOTE: Please note that we have verified with the Transcend micro SD card. This test basically
reads/writes few bytes to the SD-card.
13
www.ngxtechnologies.com
Quick Start Guide: BlueBoard-LPC11U24/37
4.3.6 ADC
Test setup and verification:
The ADC pin is connected to a potentiometer. To test the ADC rotate the wheel of the potentiometer, as
the position varies the ADC value sensed is displayed on the GLCD.
Note: Since the LPC11U24/37 has a 10-bit ADC, the values of the ADC reading will range from
0x0000 to 0x1023.
4.3.7 PS/2 Keyboard
Test setup and verification:
Connect a PS/2 keyboard to PS2 connector. Press any key on the keyboard. The corresponding key gets
displayed on the GLCD
4.3.8 USB
Test setup and verification:
Connect the USB cable to USB connector. The power LED (D7) turns ON. The USB enumeration can
be checked in device manager. The BlueBoard enumerates as a Human Interface Device (HID). On a
Windows machine this can be confirmed by looking in to the ‘Device Manager’ under ‘Human Interface
Devices’.

Quick Start Guide: BlueBoard-LPC11U24/37
4.3.9 UART
Test setup and verification:
Open the hyper terminal as shown in the below image. To test the UART open the hyper terminal with
settings 115200 bps 8N1, i.e.
Baud Rate: 115200 bps
Bits: 8
Parity: None
Stop bits: 1
Flow Control: None
Fig. 10
A ‘Connect To’ window opens where you have to select the COM port. In this example it is COM8.
Click OK. A ‘COM8 Properties’ window appears. Set the values as shown below. Click OK.
Note: Please check for your machines COM port number. The COM port number can be different.

Next a ‘Hyper Terminal’ window opens as shown.
Fig. 13
Make sure the board is powered and the serial port is connected to the board. The key that are typed on
the keyboard are echoed back to the hyper terminal.
4.3.9 External Interrupt Switch & Wakeup Switch
Test setup and verification:
When you press the External Interrupt Switch (External SW3) the controller enters into the deep power
down mode, once you press the wake up switch (SW1) the controller wakes up from the deep power
down mode.
