MM32 Review Data [Copy link]

 

Hi: Friends! Good evening. First of all, I would like to thank the friends in the forum for their positive response, support for domestic brands, and willingness to spend time testing. At present, some friends have reported that they have encountered some problems in the evaluation of MM32. The main reason is that we have not done a comprehensive enough job. In fact, the original chip is very good. It’s just that the relevant information of the board is not complete. Today I will send the schematic diagram of the board and the reference software library here. Friends can also go directly to the MM32 official website to download (registration is not required) or contact me privately. There is no problem. I will reply in time when I see it. Thank you for your support. If you encounter any problems in the evaluation, you can give feedback in time. The original download link is as follows: http://www.mindmotion.com.cn/download1.aspx In addition, regarding the LED2 on the board, there is no jumper cap installed when it is sent out, so please pay attention. You can operate LED2 by short-circuiting the board. Otherwise, the LED routine will not be reflected. In addition, the program in the attachment is the supporting routine for other development boards of MM32, not the supporting routine for this board. Please pay attention when using it. Some ports and peripherals are not connected and need to be configured by yourself. This board is the minimum system board Thank you everyone!

Hello, some friends got the board with MM32F031C8T6 as the main controller. Don't panic, this is an M0 product and can be used normally. The pins are basically the same as 103C8T6. I have also updated the routine library that will be used. Please pay attention when using it. MM32 is actually very easy to use. It is recommended to use Jlink for debugging and simulation. If you have any questions, please leave a message and I will solve it as soon as possible.

What does o,p,nm version mean?

The versions representing different series of chips are currently available in the forum. The N version is the correct one to download.

Tested JTAG/SWD/ISP, all failed. Is the ISP software on the official website really usable? Jtag and SWD modes, I don't know if it's a problem with my board or something else. Anyway, I still can't burn the firmware https://en.eeworld.com/bbs/thread-1056006-1-1.html

If ISP works, I'll use ISP to download it. You can try reinserting the USB or restarting the software.

Now it is done. I changed to a Jlink and can use SWD mode to download. I am moved. The JLink tested before is the V7 firmware. I don’t know if it is affected by this. As for ISP, I use the software on the official website. There is no response when I click the connection. I will take a look later. I will go to the code first.
