The main characteristics of the M451 series chip are shown below:
Fourth, NU-LINK emulator introduction
NUVOTON NU-LINK Debug Adapter is a USB Adfissor and Programmer based on a SWD (SERIAL WIRE DEBUG) signal interface for developing NUVOTON NUMICRO series chips. According to different development needs, it is divided into NU-LINK-PRO, NU-LINK and NU-LINK-ME. In the case where there is no specification, the above three specifications are referred to as Nu-link adapter.
1, Nu-link emulator comparison. As shown below:
2, NU-LINK emulator introduction
NU-Link Adapter supports an ICP (In-Circuit Programming) project based on the SWD signal interface, users can use Nuvoton Numi ICP Programming Tool development software for chip firmware updates, and also apply to chip firmware mass production. And support third-party development tools, such as Keil Rvmdk, Iar Ewarm and Coocox Coide.
Nu-Link is an essential admissor (Programmer) with debugging, online programming, offline programming. A USB port is linked to a computer host, a set of status indicators (STATUS LED), a offline programming button, a SWD port link target chip is adapted to program, the SWD port voltage is fixed to 5.0V. As shown below:
3, NU-Link main function. NU-Link Adapter provides a complete NUMICRO family debugging and programming feature and supports multiple third-party development tools. As shown below:
4. Online programming refers to the download of NuMICRO family microcontrollers to the target chip under the operation of computer software. As shown below:
5, offline programming refers to the software of Nu-Link directly updates the NUMICRO family microcontroller, and does not operate via computer software during offline programming. Offline programming is suitable for mass production, software developers do not need to give the original code or software file to the production line, only need to transfer NU-Link to make quantitative production. In addition, NU-Link supports a limited number of offline programming, which can effectively control the number of authorizations of software. As shown below:

V. Drive installation
1. Open the disc to find Nu-link_keil_driver, then double-click to install it. As shown below:
2. Connect the computer and develop board through the Mini-USB, when plugging in USB, it will drop, and the driver is completed. As shown below:
6. Development board test
1. Open MDK, here is not a detailed explanation of new projects. As shown below:
2, select Options for Target -. 1882.debug Select Nuvoton Nu-link Debugger. As shown below:
3. Select NOVOTON NU-LINK Debugger in Utilities and click Setting for related settings. As shown below:
4, the effect show. As shown below:
Seven, small knot
The NU-LB-M451 development board is quite good. Through simple testing, the entry makes the new Tang's single-chip microcomputer, the development board function is very perfect, whether you are a student or engineers are a noncomperable board. The development board adds a TFT LCD screen to make the entire board design more convenient, test and learning. The New Tang develop board provides a good solidware library and a considerable number of routines, enough for beginners to get started. The only flaw is that the pin of the development board requires developers to sell their own welding, of course this may be customized.
