How does MSP430 download programs to the board?(IAR MSPFET CCS)

How does MSP430 download programs to the board?This question is actually very simple, but I suffered a big loss just a few days ago, and I didn't understand it for a day.Let's talk about the pits I have walked through in this article, I hope it will help you.

1. Download IAR development IDE + serial port download tool

I AR is not the official development tool of TI. Although it is a third-party development tool that has obtained official support, it is still a little troublesome in the environment configuration, but his interface is good-looking, which is the reason why I installed him in the first place.(But it doesn't seem to be as good as the official CCS)

After compiling into hex or txt in IAR, use the serial port FLASH burning tool to burn

I heard that IAR is also a serial port tool that is automatically installed after downloading. However, after I inserted the board, there was no MSP device in the device manager, but only two ordinary USB devices. I found a lot of ways to install a lot of driversAfter that, the MSP driver is displayed, and then the MSP-FET still cannot be downloaded because the port cannot be found.

2. Download Code Composer Studi IDE+Official SDK from the official website

You don't need to go to many IDEs like IAR and GCC, it is very convenient to use the official CCS, and the interface is very handsome, the user experience is also very good, it is also very fast and convenient to use with the official SDK, and the recycling of the installed software will remind youWhether it is partially installed or fully installed, select the corresponding board for partial installation. If all installed, the installation will be slower

It is worth noting here that the installation path cannot be in Chinese, and the user name of the computer cannot be in Chinese. In this case, the installation may fail, or the installation may crash or fail to use.

Download link: CCS IDE and Development Tools | Design Resources | Texas Instruments TI.com.cn

After installing the IDE, you need to install the corresponding chip SDK. Take MSP430 as an example to download the link: MSPWARE Software Development Kit (SDK) | TI.com.cn

After downloading and installing, there are many examples in the SDK and a very convenient local document, which is also very convenient to use

The newly created project contains the file address of the SDK library file. Right-click Properties in the project navigation bar on the left and select build-MSP430 Compiler-Include Options

And MSP LinkerFile Search Path

That's it, you can run the official routine. If there are no errors in the compilation, you can click the debug button to start downloading and debugging. If it is the first time for a new board, you need to upgrade the onboard BLS download module.

Subsequent development is very convenient, but there are still someInconvenient places, such as the inability to observe changes in variables in real time.
