[MM32 eMiniBoard Review] Building a development environment - lighting up the onboard LED [Copy link]

 

I got the board a few days ago. As the year is coming to an end, I have been busy recently. Today I started to formally evaluate this board. The resources on the board are relatively rich. I also plan to run the resources on the board before starting to conceive and create a small DIY product. Without further ado, the board is connected to the USB of the PC, and the DEMO runs when it is powered on. The music and lights are on, which is quite interesting. I saw other students complaining about the problem of the board automatically playing music. I casually pressed the K1 button of the development board and the music stopped. It seems that this student did not experience it seriously. However, it is indeed a bit inconvenient that there is no reset button. This design is a bit wrong.

Since I had never used Lingdongwei's MCU before, I was a complete newbie. After connecting the development board to the computer via USB, the PC recognized the MM32-LINK and installed the Keil PACK package. I found that Keil's DEBUG option did not recognize the MM32-LINK emulator.

Go to the official website to download the driver package required for the EMM32-LINK emulator, unzip and install it after downloading, and click Next all the way. After the download and installation are complete, Keil's DEBUG clock can select EMM32-link. Next, try to light up the onboard LED.

Following my usual style, I re-created a project to store various files. I started to create a new Keil project file. In order to get started quickly, I directly used the official library file to build the development environment and simply transplanted the official LED routines into my own newly created project file.

This example program uses the K1-K4 buttons on the development board to control the lighting and extinguishing of the LD1-LD4 onboard LEDs. After the development environment is set up, recompile it, download it to the development board and run it. Everything is normal and the expected effect is achieved. Tomorrow, we will start to do more applications and evaluations on this project.

Haha, you are smart enough to press the button to see if you can stop the music.
