"Special Declaration:" 2017 China Site Electronics Zhigang Innovation Competition "is about to start, and the panel network will renew the evaluation of the officially designated board of the competition. These boards can be applied free of charge when they online, as long as you have reasonable application reasons, We will send you a board development.
NXP This LPCXPRESSO54608 development board can apply for this board for free when starting in the 2017 SCIENCE INTRO. View developer details >>
At the beginning of the New Year, the NXP heavyweight released a new generation of ARM Cortex-M4 LPC546X series high-performance microcontrollers, which relaxed with new development boards based on this series of microcontrollers - NXP LPCXPRESSO54608. What kind of performance will this range of microcontrollers? What is the function of the board? Do not nonsense, the pavilion is directly smashed to the guys.
The palette of the pavilion is LCPXPRESSO54608, which is the new new product in the first quarter of NXP 2017.
Speaking of this, we can insert the NXP's 2017 product roadmap, of course, mainly the two product lines of the microcontroller, the following planning, one is based on the ARM Cortex-M0 + LPC800 series, mainly used to replace 8 bits Single chip market, this series of products combine low-cost low-cost applications; it is the upgrade of the LPC546X series of the LPC546X series of this article, with the Essence of the LPC1700 series, providing engineers with advanced integration and ultimate flexible connection characteristics, The application sector includes motor, audio, human-computer interaction interface, etc. At present, NXP is still steady, low-end and high-end dual privileges in 2017.
LCPXPRESSO54608 development board
Long, return to the LCPXPRESSO54608 card itself, board the board is equipped with a 480 * 272 resolution capacitive touch screen, which is very helpful. After all, I haven't equipped with such a big touch screen in the IXP development board. Board, now there is a screen, playability is greatly enhanced.
The board is on additional to the screen, all the devices are distributed on the back of the board. The first time I saw the back of the board, I feel very complicated, more interfaces, more hops, of course, the corresponding function is definitely more. It seems that many features are implemented on these jumbs, which has increased in the players, and the cost of learning has also increased, but the increase in functions will be more than the increase in learning costs.
The main resources of the LPCXPRESSO54608 onboard are as follows:
LPCXPRESSO54608 Development Board Board Resources:
272x480 color LCD capacitive touch screen
Onboard High Speed USB, LINK2 Debug Probe (with CMSIS-DAP, SEGGER J-LINK Protocol)
Support external debug probe
3 users LED, and reset, ISP (3), and user buttons
Multiple expansion options include Arduino Uno and PMOD
Built-in LPC546XX MCU power consumption measurement
128MB Quad-SPI Flash (Micron MT25QL128)
8MB SDRAM (Micron MT48LC8M16A2B4)
KNOWLES SPH0641LM4H Digital Microphone
Full size SD / MMC card slot
NXP MMA8652FCR1 accelerometer
Stereo video code decoding, with signal input and output
High-speed and full speed USB port with Micro A / B connector, support Host and Device mode
10 / 100Mbps Ethernet (RJ45 connector)
Learn from the onboard resource of the development board, the LPC54608 is still a very good function and features combined with many popular elements:
First, that touch screen is undoubted, the capacitive touch screen is not a playing board, which greatly enhances the playability of the development board.
Second, the development board is equipped with a complete audio application, including audio-won decoding chips, microphone input, headphone output, SD storage, which is still uncommon on the microcontroller board, basically some high-end microcontroller boards Talented features;
The third point is that the development board is compatible with the current popular Arduino extension interface, which is convenient for porting some types of forms on the current market.
In general, I am very satisfied with the onboard resources of LPCXPRESSO54608, the function is very high, and the versatility is relatively strong, but it is necessary to say that the impressive flash point is not obvious. Of course, the highlights of the board itself are still onboard this new upcoming microcontroller, so let's take a look at it differently.

LPC54608 microcontroller
It is well known that the resources of a development board and most of the peripherals depends on the characteristics of the microcontroller. From the LPCXPRESSO54608, we can understand the function of some LPC54608 microcontrollers. The microcontroller is based on the ARM Cortex-M4 processor, the maximum frequency is 180MHz, using TFBGA180 package, size of 12mm * 12mm, suitable for high-performance embedded fields with high spatial sensitivity.
The hardware resource block diagram is as follows: (click on the picture to enlarge)
As can be seen from the following table, the LPC54608 belongs to the highest specifications in the LPC5460X series, with 512KB Flash, 200KB SRAM, with high-speed / full speed USB interface, Ethernet interface, CAN interface, LCD interface, maximum scalable 145 GPIO ports, features and scalability are very powerful.
NXP Debug Link Circuit and SWD Debug Interface.
Compatible with the Arduino UNO extension interface.
PMOD extension interface
High Speed / Full Speed USB Interface, Power Interface, Debug Interface
Audio input output interface, 100M Ethernet interface, SD card holder
User button, PMOD interface
Some of the interfaces on the boards described above are marked on the board, which is unclear, with reference to the user manual provided by NXP, at a glance, this is not called.

LCPXPRESSO54608
When I use it, I am actually worried. After all, it is a new product. I have a lot of pits. At adventures are going to prepare for the pit. If the board, the 4 MicroSB interface can provide power, run the built-in factory program, any MicroSB interface directly receives the PC, if the engineer needs to connect a large number of peripheral function modules, plus the screen and other resources, can consider Powering the adapter, after all, we usually have a 500mA output current on the computer is not enough.
The board is moving amazing, and the LPCXPress54608 is actually a TouchGFX program.
Sensor measurement application
Chart application
Report display application
This is the UI interface program that I personally prefer. TouchGFX is a unique software framework that can be comparable to a graphical user interface (GUI) on your smartphone, so that you can switch menus display effect on the list and preview graphic display mode. Very cool. And from these applications, the MCU's usage is really low, only 2% to 3%, which can be seen that for the mid-term MCU product application, this graphical interface is simply killer Function.
Holding a happy mood is originally imagined in Touch GFX to download the source code, and the result is given to the basin cold water. Official posting to March this year.
No way, I can't play Touch GFX. I can only look at it. If I have a good relationship with NXP, I may also get the source code in advance.

The development tools for LPCXPRESSO54608 support their own LPC microcontroller utilities and third-party IDE tools such as Keil, IAR, etc.
LPCXPRESSO54608 sales board package can go to McUXpresso configuration tool website download
The deployment of the website is very friendly, allowing engineers to choose the smallest package download.
For example, engineers prefer to use Keil, then choose the environment you need to develop, IDE tools can choose Keil
After choosing the recommended package, you can download it, but there is a point worth vomiting. When you download it, you don't support the download tool download, and it seems that these SDK servers are abroad, and the download is very slow. Download is complete, you can develop it through Keil.
It should be noted that if you first contact the LPC546X series microcontroller, you also need to update the KEIL Database
Because the NXP package has provided several basic routines, I will directly take the more intuitive touch screen routine, and after the completion of the completion, I encountered problems during the download, and I can't read the board CMSIS-DAP. debugging.

At the beginning, I thought Ide tool settings, but there is still no effect after the modification, and I look at the NXP user manual to find that using CMSIS-DAP debugging requires the following hop to remove.
Re-power it to find the debugger onboard.
Compile, download
debugging
Square
Then I tried another routine, wake up the device from the sleep through the Microtick Timer, and output the following clock signal.
Sleep state
Wake-up clock signal can be measured by oscilloscope
