NXP LPCXpresso54608

LPCXpressoV3 development board for NXP LPC5460x processors

MCU Features¶

The LPC546xx MCU family combines the power efficiency of the Arm Cortex®-M4 core running at up to 220 MHz with multiple high-speed connectivity options, advanced timers, and analog features. DSP capabilities enable LPC546xx MCU devices to support complex algorithms in data-intensive application. Providing flexibility with up to 512 KB Flash and external memory interfaces, this family provides the ability to adapt as requirements change. Flash options support large, flexible internal and external memory configurations. Compatibility within the LPC54000 series enables the LPC546xx MCU family to provide a seamless migration path for increasing processing power and adding the flexibility of additional advanced peripherals.

• LPC54608ET512 Arm Cortex-M4 running at up to 180MHz
• 512 KB Flash
• 200 KB SRAM
• Flexible internal and external memory configurations

Board Features¶

The board is comprised of target LPC54608 device with an on-board, CMSIS-DAP / SEGGER J-Link compatible debug probe. The on-board probe is compatible with MCUXpresso IDE and other leading toolchains such as those from Keil and IAR. The board is also equipped with a standard 10-pin header enabling the use of 3rd party debug probes. In addition to standard LPCXpresso V3 features, this board includes a complete set of peripheral interfaces to enable developers to fully explore the capabilities of LPC5460x devices.

Getting Started with mbed¶

1. Connect your microcontroller to a PC¶

Use the USB lead to connect your mbed to a PC. The status light will come on, indicating it has power. After a few seconds of activity, the PC will recognise the mbed Microcontroller as a standard USB drive.

Windows XP example	Mac OS X example

2. Click the PRODINFO.HTM link to get logged in¶

Go to the new USB Drive, and click PRODINFO.HTM to open it in a web browser.

If you do not have an mbed account, choose "Signup", and create your mbed Account. Otherwise, log in with your normal username and password.

This will give you access to the website, tools, libraries and documentation.

PC Configuration¶

Your mbed Microcontroller can appear on your computer as a serial port. On Mac and Linux, this will happen by default. For Windows, you need to install a driver:

From a host PC to communicate with mbed you will need a terminal application. This allows the mbed Microcontroller to print to your PC screen, and for you to send characters back to your mbed.

• Terminals - Using Terminal applications to communicate between the Host PC and the mbed Micrcontroller

Some terminal programs (e.g. TeraTerm) list the available serial ports by name. However, if you do need to know the identity of the serial port so that you can attach a terminal or an application to it:

	Windows		Mac		Linux
	Find the identity of the COM port by opening ''Device Manager''. To do this navigate ''Start -> Control Panel -> System -> Hardware -> Device Manager''.		To find the device name under Mac OS X, use the command ''ls /dev/tty.usbmodem*''		To find the device name under Linux, use the command ''ls /dev/ttyACM*''

Downloading A program¶

1. Save a program binary (.bin) to the Platform¶

Download the appropriate "Hello World!" binary:

• LPCXpresso54608: HelloWorld_lpcxpresso54608.bin

Note: the source code for this program will be seen in the next section.

Save the program binary file to your mbed Microcontroller Disk, just like you would with a normal USB disk. The Status LED will flash as the PC writes the file to the Microcontroller disk. The file is now consumed.

2. Press the Reset Button¶

When the Reset Button in pressed, the microcontroller will be reset and the last programmed application will begin to run.

3. Hello World!¶

The Microcontroller is now running the program; flashing LED1 forever! If you reset the Microcontroller, or disconnect and reconnect the power, the program will simply restart.

Open Existing Project¶

1. Import the Program to your mbed compiler¶

Select Import As Program
Choose Import Name of your preference
Click on Import

[Repository '/teams/mbed-os-examples/code/mbed-os-example-blinky/' not found]

2. Compile the Program¶

In the right panel Program Workspace Select the program you want to compile
Click on Compile in toolbar
If compilation ends successfully, you should see the comment Success! displayed in the Compile Output window available in the bottom and your web browser should download automatically the precompiled binary for the program.

3. Download a (.bin) to the Platform¶

Save the program binary file to your mbed Microcontroller Disk, just like you would with a normal USB disk. The Status LED will flash as the PC writes the file to the Microcontroller disk.

4. Press the Reset Button¶

When the Reset Button in pressed, the newest program on the mbed Microcontroller Disk will be loaded in to the Microcontroller FLASH memory. The Status LED will flash as this happens.

When the program is has been loaded onto the microcontroller, it will then start it running.

5. Run the Program¶

The Microcontroller is now running the program; flashing LED1 forever! If you reset the Microcontroller, or disconnect and reconnect the power, the program will simply restart.
