3. Getting Started

By default, the LPCXpresso54114 is configured to use the on-board debug probe (Link2)

to debug the on-board target (LPC54114), using the CMSIS-DAP debug protocol pre-

programmed into the Link2 Flash memory. The LPCXpresso IDE (available for free

download at http://www.nxp.com/lpcxpressoide) or development tools that support the

CMSIS-DAP protocol can be used in the default configuration. Check with your toolchain

vendor for availability of specific device support packs for the LPC54110 family of

devices.

Note that when using the LPCXpresso IDE, the on-board Link2 can also be booted in

DFU mode by installing a jumper on JP5; if this is done then the IDE will download

CMSIS-DAP to the probe as needed. Using DFU boot mode will ensure that the most up-

to-date / compatible firmware image is used with the IDE. Note that spare jumpers are

provided in the board packaging, taped to the card insert beneath the board.

Installation steps for use with LPCXpresso IDE on a Windows 7/8/10 platform (booting

Link2 in DFU mode):

1. Download and install the LPCXpresso IDE (version 8.1 or later).

2. Install JP5 to force the Link2 debug probe to boot in DFU mode (see notes above).

3. Connect the LPCXpresso54114 board to the USB port of your host computer,

connecting a micro USB cable to connector J7 (“Link”). The board will boot a simple

LED blinky example using the tricolor LED, alternating between red and green.

4. Allow about 10 seconds for the LPCXpresso54114 devices to enumerate for the first

time; the device will appear as “LPC Device”.

5. Download the LPCOpen examples & drivers from https://www.nxp.com/lpcopen or

https://www.nxp.com/OM13089, selecting the version for the toolchain you are using;

project files for LPCXpresso IDE, Keil and IAR tools are available.

6. Start the LPCXpresso IDE and import the LPCOpen zip file by clicking Import

project(s) in the “Start here panel.”

7. The simplest example is periph_blinky, which will blink the tricolor LED (fast blinking

of the red LED) on the LPCXpresso54114. Click on the periph_blinky in the “Project

Explorer” panel, then click Debug ‘periph_blinky’ in the “Start here” panel. This will

build the project and then launch the debug session.

8. After detecting and booting the Link2, the IDE will prompt for selection of the

processor core to debug – M4 or M0. Select the M4 target. Note that after this

selection has been made once for a given project, the IDE will assume this as the

default for that project.

9. The IDE will show a source code window and break at the function main(). Press F8

(or use the Resume icon) to run the program.

Installation steps for use with third party tools on a Windows 7/8/10 platform (Link2

configured for CMSIS-DAP):

1. Download and install LPCScrypt or the Windows drivers for LPCXpresso boards

(http://www.nxp.com/lpcutilities). This will install required drivers for the board.

2. Ensure JP5 is open to force the Link2 debug probe to boot from internal flash.

3. Connect the LPCXpresso54114 board to the USB port of your host computer,

connecting a micro USB cable to connector J7 (“Link”). The board will a simple LED

blinky example using the tricolor LED, alternating between red and green.

4. Allow about 30 seconds for the LPCXpresso54114 devices to enumerate for the first

time. It is not necessary to check the Hardware Manager, however if this is done

there will be five devices; four under Human Interface Devices (CMSIS-DAP, LPC-

SIO, two HID Compliant Devices, and a USB Input Device) and one under Ports

(LPC-LinkII Ucom.)

5. Your board is now ready to use with your 3rd party tool. Follow the instructions for

those tools for using a CMSIS-DAP probe.

4. LPC54114 Serial ports

By default the LPC54114 UART0 is connected to the FTDI header at J5. This can be

used for ISP booting or sending debug messages out to a host computer via a suitable

cable. The LPC54114 UART0 can also be connected through a virtual communication

port (VCOM) UART bridge Link2 function to a host computer connected to the J6 USB

Link2.

The factory default CMSIS-DAP Link2 image includes UART bridge functionality (VCOM

support), and this firmware is also available with the LPCScrypt utility, available at

http://www.nxp.com/lpcutilities. When running this firmware the default source of data to

the LPC54114 RXD is the FTDI header. Once the Link2 receives any data via the VCOM

port of a host computer it will set P2_2 low to select the Link2 UART0 data to the

LPC54114. In order to reset this so the FTDI connection can be used it is necessary to

power cycle the board.

4.1 P3 FTDI header

The FTDI header P3 mates with FTDI cable TTL-232R-3V3. P3 interfaces the LPC54114

UART0 to a Host PC virtual serial port. The location of P3 is shown in Fig 3. The pin out

and a description of the signals at P3 are listed in Table 2.

5. Board power connections and measurement

The LPCXpresso54114 board requires +5V input to power the on-board voltage

regulators which in turn power the Link2 debug probe and other +3.3V circuits, the

LPC54114 target and other +1.8V circuits, and the Arduino +5V and +3.3V power rails.

When the main external power source is from the Link2 side USB micro B-type connector

(J7), both the Link side and LPC54114 Target sections of the board are powered. When

the main external power is from the Target side USB micro B-type connector (J5), or

FTDI header (P3) only the LPC54114 Target section of the board is powered.

A block diagram of the board power tree is shown in Fig 4. When the LPC54114 Target

is to be debugged from an external debug probe, instead of the on-board Link2 debug

probe, the Link USB connector (J7) must be disconnected. The circle with I indicates

where the current monitoring circuitry measures / where an ammeter can be inserted.

the default.

Fig 4. Board power diagram

5.1 LPCXpresso54114 current measurement

The LPC54114 current can be measured by measuring the voltage across a sense

resistor in series with the supply, a current meter or using the on board current

measurement circuit. Each of these methods will be described in subsections below.

There is no current monitoring of the Link2 section circuits on the board. The Target side

power going to LEDs and support ICs is not monitored by the current measurement

circuit. The LPC54114 LQFP package has the core and IO power both sourced from the

same VDD pins.

When a shield board is attached, attempting to measure the lowest possible power the

LPC54114 IO pins must be configured according to how the software has configured the

shield board to ensure there is no extra current from the LPC54114 IO ports that have

external pull-up or pull-down resistors enabled. JS19 should be opened to ensure no

leakage through the tri-color LED and +3.3V supply, and JP6 opened to avoid leakage to

the Link2 via the I2C and SPI connections between it and the LPC54114.

5.1.1 LPC54114 Vsense resistor current measurement

The voltage across a series 4.12Ω resistor with the target LPC54114 VDD can be

manually measured at P2 on the PCB. The voltmeter positive probe is applied to P2 pin

1 (square pad) and negative probe to P2 pin 2. Use Ohm’s law to calculate the current

(LPC54114 current = measured voltage / 4.12Ω). As an example if the measured

voltage is 10mV, then 10e-3 / 4.12Ω = 2.44mA. Note that the input current to the

MAX9634 used in the on-board current measurement will be included in the voltage

measured across this resistor.

5.1.2 LPC54114 VDD current measurement using a current meter

A current meter may be inserted at JP4 to measure the LPC54114 VDD input current.

The 0Ω resistor at JS11 must be removed and the current meter connected at the

positive input at JP4 pin 1 (square pad) and negative input at pin 2.

5.1.3 LPC54114 VDD current measurement

The LPCXpresso54114 board has an on-board current measurement circuit consisting of

a MAX9634T (U5) current monitor chip and a 12-bit ADC (ADC122S021, U11) with a 12-

bit sample at 50k to 200ksps. The on-board MAX9634T current monitor measures the

voltage across the LPC54114 VDD vsense resistors; either 8.24Ω or 4.12 Ω if JP3 is

installed. The MAX9634 multiplies the sense voltage by 25 to provide a voltage range

suitable for the ADC to measure. A 2-input analog mux selects between the LPC54114

current monitor and the output on a MAX9634T current monitor chip on an expansion

board (with compatible current measurement circuit on-board). The current measurement

circuit is controlled by the Link2 processor and is not user programmable. Power

measurement utilities to use this feature are available in the LPCXpresso IDE installation.

Due to input offset voltage variations in the MAX9634, the current measurement circuit is

not recommended for measuring current below 150uA. See Fig 5 as a guideline for

measurement error versus measured current.

5.1.4 Shield board current measurement

To use the on-board current measurement circuitry, any expansion board must match the

functionality of the LPCXpresso54114. Refer to the board schematics for more

information.

6. Debug Configurations

The LPCXpresso54114 LQFP board has a built-in debug probe referred to as “Link2”.

The LPC54114 target MCU can be debugged by the Link2 debugging probe, or from an

external debug probe installed at P1. On-board jumpers JP1 and JP2 must be correctly

positioned for each mode. The on-board Link2 debug probe is capable of debugging

target MCU’s with a VDDIO range of 1.6V to 3.6V. Use JP9 to set the LPC54114 chip

VDD to the desired voltage level (+1.8V or +3.3V). Check the sections below for the

appropriate jumper settings and how to properly power the board.

6.1.1 Debugging LPC54114 target using on-board (Link2) debug probe

To use the on-board Link debug probe, the LPCXpresso54114 board must be powered

from the Link2 USB connector J7, and jumper JP2 must be fitted in position pin 1 - 2

(Local Target). Jumper JP1 must be open to enable the target LPC54114. Connecting

the micro USB J7 to a host computer will power the Link and Target sections of the board

and provide the USB link to the debug tool software.

6.1.2 Debug LPC54114 target using external debug probe

To use an external debug probe, connect the probe to the SWD (P1) connector, power

the LPC54114 Target section of the board from the Target micro USB connector J5, and

fit a jumper to JP2 across pin 1 - 2 (Local Target). Jumper JP1 must be open to enable

the target LPC54114. The on-board Link2 debug probe must be unpowered, by leaving

J7 unconnected.

6.1.3 On-board Link2 flash programing

To program the Link2 Flash the Link2 MCU must be in DFU mode. If the Link2 already

has a valid image in the flash, you will need to force it into DFU mode by placing a

jumper shunt on JP5, then power the board by connecting the micro USB J7 to a host

computer. Link2 MCU programming is performed using the LPCScrypt utility (see

http://www.nxp.com/lpcutilities). Instructions for using the tool are located at the same

web page.

6.2 Using on-board Link2 to debug an off-board target LPC MCU

The LPCXpresso54114 board’s Link2 debug probe may be used to debug an off-board

target MCU. The on-board Link2 debug probe is capable of debugging target MCU’s

with a VDDIO range of 1.6V to 3.6V. To keep the on-board target LPC54114 MCU from

interfering with the SWD interface, JP1 must be fitted. The Link2 debug probe SWD is

connected by a ribbon cable between the P1 connector to the off-board target MCU SWD

interface. Power the LPCXpresso54114 board from the Link USB connector J7, and fit

jumper JP2 across pins 2 - 3 (External Target).

of the tri-color leds, JP6 must have a shunt between pins 1 – 2. By default

the 0Ω resistor at JS17 provides the shunt for JP6. To measure the lowest

possible current from LPC54114 remove the 0Ω resistor at JS17 (remove

+3.3V from led common anode).

8. Expansion connectors

The LPCXpresso54114 board includes four expansion connectors plus a PMod™

compatible connector (J3). The expansion connectors (J1, J2, J8 and J9) incorporate an

Arduino Uno revision 3 footprint in their inner rows. Not all connector locations are

populated on the expansion connectors since the LPC54114 does not have enough I/O

to utilize all of the available connections (additional pin locations are provided for

compatibility with future LPCXpresso boards).

This button is used to reset the LPC54114 (note that the Link2 is NOT reset by this

button.)

9.2 ISP0 and ISP1

These button connect to the LPC54114 P0_31 (ISP0 button) and P0_4 (ISP1 button) pin

and may be used to force the LPC54114 into its various ISP boot modes. See Table 5.

To force entry into one of these boot modes hold down the required button(s), press and

release the Reset button, then release the ISP button(s).

Note that for USB Mass Storage boot to work, a USB host must be connected to J5 and

JP10 must be installed in order to route Vbus to the LPC54114. When the LPC54114 has

been booted in mass storage mode a firmware image (which must be named

firmware.bin) can be virtually “dragged and dropped” onto the board (which appears as a

mass storage device called “CRP DISABLED” on the host computer) using a file

manager utility (such as File Explorer on Windows, or Finder on MacOS). Before

dropping new firmware onto the board the existing firmware.bin needs to be deleted.

This can be useful when the LPC54114 flash has been programmed with code that

disables the SWD debug pins or changes timing settings such that the debug probe has

problems communicating with it. The ISP buttons can be used to force the LPC54114

into a state where the debugger can regain debug control.

The ISP buttons can also be used to trigger an interrupt by configuring the P0_31 / P0_4

pins and associated interrupt controls within your application code.

9.3 WAKE

This button can be used to generate an interrupt by pulling down the P0_24 of the

LPC54114.
