At present, there are a lot of Internet development boards launched in the market, and many of the cloud service platform manufacturers have launched free to send to users, and the actual design of these development boards is completed, so that many users use them if they use them In the case of some hardware issues, it is difficult to solve the rapid resolution, delay the product development, so choose the way in the way when choosing product development. Numaker Platform is the platform developed by the new Tang to the Internet application, supports ARM Mbed OS 5, suitable for all types of application development, and supports universal Arduino interface, allowing users to quickly join the sensing and wireless modules for prototype equipment design. At present, the new Tang provides Numaker-PFM-NUC472 and Numaker-PFM-M453 two platforms. Today, I will share the name of Numaker-PFM-M453.
Numaker-PFM-M453 development board
Numaker-PFM-M453 is equipped with a Cortex-M4 processor, the main control board adopts a general-purpose interface design, providing a compatible Arduino UNO interface, and users can develop any Arduino module. In addition to the expansion interface, the main control board itself also has a rich interface device such as buzzer, three-color LED, button, microphone, headset, USB OTG, three-axis accelerometer and a three-axis gyroscope sensor.

In general, the Numaker-PFM-M453 main control platform launched in New Tang has a safe, communication and equipment management module, supports low-power BT, Thread, Wi-Fi, 802.15.4 / 6LowPan, TLS / DTLS, COAP, HTTP, MQTT, and a lightweight M2M, a built-in 32-KB SRAM and 256 KB Flash configuration, suitable for operation of the Internet of Things equipment.
Development environment
The most important upgrade of this Numaker-PFM-M453 development board can be said to support the ARM Mebed project, what is the ARM Embed project? Mbed is a prototype development platform for the ARM Cortex-M series processor, which is mainly used to cultivate the IoTs (IOT) collaboration project, including free software library (SDK), hardware reference design (HDK) and online tools (web ) Three parts, providing users with simple, convenient and fast-based MCU development, commissioning, etc. based on ARM Cortex-M processor. In addition, Mbed also greatly simplifies the process of downloading procedures, just put the cloud-compiled bin files to the U disk in the way, the specific process can refer to the following process.
Connect the Numaker-PFM-M453 development board to the PC side, you can see a U disk taken below in your computer.
There is a URL that points to the cloud compilation tool in the u disk, and it can be directly reached, which is very convenient.
At this point, open the editor of the webpage and create a new project file. It can be seen from the figure below that the cloud has been included in the new Tang Numaker-PFM-M453 platform.
The pattern of the editor of the webpage, the code is the button controlled the LED and the buzzer.
Compilation completion will prompt to generate a .bin file
Download file to board is the most convenient operation, drag into the U disk
Operation buttons can see feedback from LEDs
In addition, the new Tang Numaker platform can also be seen on the cloud Numaker platform, with source reference reference for sensors, wireless networks, motor control, etc., although the association is not large, but the win is more .
The Numaker-PFM-M453 can be used as a set or sensing end node, connected to the cloud server, ensuring safe connection and management equipment, transmitting the micro data to the cloud through the MBED server software, and then via big data Analyze technical processing, you can generate value information.
Interested friends do not play personally experienced, Numaker-PFM-M453 development platform has free application trials in the development board trial channels of the panel.
summary
Introduced new Tang's latest development platform Numaker-PFM-M453, equipped with complete audio circuits, debuggers, support universal Arduino interface, suitable for expanding various sensors or wireless modules, more worthy of praise, New Tang The development board is finally compatible with the ARM MBED OS cloud IDE tool. It is very simple to use. It is even simple and rude. Don't download the huge IDE installation file, don't worry about it, don't use license or to find crack methods, no need to be professional The guide will be handed next step, just open the web page, enter the account to be perfectly used. Of course, there are quite a lot, one is the restriction of debugging, the cloud IDE does not support online debugging, but the new Tang microcontroller itself supports third-party IDE tools, and can match the cloud IDE tool, each other In short, as a new Tang without your own IDE tool, ARM MBED OS support makes it as much as the chip, talking to nothing.
