The LPC5500 MCU series, world’s first Arm® Cortex®-M33 based MCU series for the mass market, has introduced new levels of performance efficiency, advanced security and functionality in the MCU space. With up to 150Mhz of core frequency (dual-core options included), 32uA/MHz of active power consumption, and tightly couple accelerators for signal processing and cryptography, the LPC5500 MCU series has become a key player in consumer electronics, building control and automation, secure applications and Industrial IoT markets.

As part of the MCUXpresso IDE v11.0.1 release, we had to make some major changes to our LinkServer debugging mechanism to support the latest silicon revision of the LPC55xx family of devices (revision 1B) and the more secure debug request mechanism required by these parts. Such silicon is supplied on LPC55S69-EVK boards marked Revision A2 (or later) on the board silkscreen.

Hello, recently I have done Periph Blinky e.g. from LPCOpen library on MCUxpresso. I am using LPC1769 chip and I have toggled GPIO pin. In my case I have used buzzer pin i.e. Port 3 & Pin 25. Instead of using Timer delay I created a delay function i.e. void delay_ms(unsigned int ms). Here I am attaching the systick.c file. Hope it helps!!  

An issue has been identified that impacts the debugging of older LPC devices using SEGGER Jlink via the version of MCUXpresso IDE v11.0.1 released on 4th September 2019.

This issue will be seen only when debugging an LPC device that use the IDE's Preinstalled part support i.e. parts that do not require an SDK - a debug operation via SEGGER Jlink will lead to an error as below:

LPC845 Breakout Board now has an SDK package available! We are working on updating our getting started information to show how to use this rather than starting from the LPC845 chip SDK. The board is called LPC845BREAKOUT in the SDK builder.

Amazon Web Services has released a preconfigured FreeRTOS example for Armv8-M and the NXP LPCXpresso55S69 board. With the addition of board- and device-specific examples, it is even easier to start and use the Arm® TrustZone® features combined with MPU (Memory Protection Unit) on the NXP LPC55xx MCU.

The ARM TrustZone is an optional secu=rity feature for Cortex-M33 which shall improve the security for embedded applications running on microcontroller as the NXP LPC55S69 (dual-core M33) on the LPC55S69-EVK.

This article covers the NXP LPC55S69-EVK board: a dual ARM Cortex-M33 running at 100 MHz with ARM TrustZone

I really love tiny and bread board friendly boards, especially if they are very affordable and can be use with Eclipse based tools. So I was excited to see the NXP LPC845-BRK board to be available at Mouser, so I ended up ordering multiple boards right away. Why multiple? Because they only cost CHF 5.95 (around $6)!

The LPC845-BRK is a great tiny sub-$6 breakout board featuring the LPC845M301JBD4 MCU:

• ARM Cortex-M0+
• 30 MHz, 64 KByte FLASH, 16 KByte SRAM
• On-board CMSIS-DAP debug interface, works out-of-the-box with NXP MCUXpresso IDE or other 3rd party IDEs
• 3 push buttons (user, RESET, ISP)
• RGB LED
• Potentiometer

We've been working on making the flagship member of the LPC800 series more accessible to more users than ever before, and are delighted to announce the LPC845 Breakout Board is now available from our distribution partners and also direct from nxp.com! Setting a new price point for a fully featured, debug enabled platform, this board includes CMSIS-DAP compatible debug and a VCOM port in a very compact yet flexible form factor. Of course it can be used with MCUXpresso IDE, Keil, IAR and other popular tools.

Using SDK drivers for LPC845 Breakout Board, this project measures the ambient light intensity by using LDR (Light Dependent Resistor). The voltage values from LDR are read through an ADC. The new LPC845 Breakout board has an SDK support which makes it a lot easier to interface an LDR for measuring light intensity compared to the conventional coding style. I have used the MCUXpresso IDE for modifying the pins and clock configuration settings.

The new LPC845 breakout board has 3 onboard LEDs- Red, Green, and Blue. The brightness of these LEDs can be controlled using a PWM signal by changing the duty cycle values for each of them. As this board has an SDK support, I have used the SDK drivers to implement this application.

If you are searching for a high-performance, power efficient, yet cost sensitive MCU for your designs, then here is the exciting news: NXP recently introduced the LPC51U68 MCU.

The LPC800-DIP board is now being sold by Coridium for just $10:

I have the OM13086 Cloud Connectivity Kit
I have been following the ZentriOS "Quickstart Guide".
As part of the Zentri OS Quickstart procedures, I chose "Custom Install", so instead of using the "Zentri IDE", I'm uisng LPCXpresso 8.2.2, with the Zentri SDK plugin

Today we announced the new LPC8N04, NFC-enabled MCU. We will be demonstrating the board at ARM Techcon in San Jose, and the lucky first 100 visitors to the NXP booth can exchange their business card for a free board!

You may be interested to know that we recently released a new set of debug firmware and Windows 7 drivers for our boards that feature the LPC11U3x MCU as a debug probe (so all the "MAX" boards). The new firmware can be found under the Software & Tools tab of the board page you are using  http://www.nxp.com/demoboard/omxxxxx (where xxxxx is the board part number, such as om13071, om13097, etc.

For the low pin count and small memory footprint LPC800 family, NXP offers free LPCOpen Driver Code and Example Code Bundles. 

The LPCOpen Driver Code for LPC81x/82x/83x series, is an Application Programming Interface (API) base. For users who are not too concerned with overall code size, LPCOpen provides the ease of use without diving into details of each peripheral registers, and it is easy to migrate from LPC8xx to LPC11xx family. 

Nice project from Kevin Townsend showing off capabilities of LPC824 with it's state configurable timer to drive Neopixel and IR distance application.

I love seeing how our LPC community uses our microcontrollers ... keep sharing what you create and let's continue to support and invest in each other.  

Hi LPC fans,

We have very good news to share with you today.

As you know, one of the major roadmap for LPC this year is the LPC546xx release.

And it will be coming soon~~~, as you all expected.

For this new and hot product, the LPC SE team has prepared a serial of training slides covering almost every peripheral and aspects of LPC546xx.

I am humbled and energized after spending a week with 30,000+ engineers at this year’s Embedded World!

Amazing.  That’s the only way to describe the passion and enormity of our LPC FANS across Europe.  LPC is deep-rooted in the hearts of many and I am lucky to be a part of this inspired, tightknit community.    Embedded World has a strong place in the heart of LPC. 

My personal highlights from the event .... LPC FANS, What's Popular, MCUXpresso & Geoff.

We gave out 200 of our LPC800 DIP breakout board (with an LPC824 installed) at Embedded World last week ... they were snapped up pretty fast! For those lucky folks who grabbed one, here is the schematic. Pretty simple stuff, probably actually easier to read on the packaging!

Some days before, there is a great post about LPC dual-core, LPC key feature_DualCore 

This time, we show a LPC5411x based dual-core example. It shows all aspects about dual-core development, startup, communicate, sync, mutex. Enjoy it:)

After extracted the attachement, it locates at "boards\lpcxpresso54114\multicore_examples\blinky\mdk\blinky.uvmpw"

The year when two titans came together forming what is now the #1 supplier to the broad based MCU market.  To the industry, it was the year of the merger, clouded in uncertainty.

Our global ecosystem - from NXP field engineers to distributors and partners are training up on LPC and now more specifically, the newest LPC546xx family.  

But we also want to make sure the engineers actually using our MCUs in their application receive the same information directly from us ... we will continue to keep you updated & informed.
