Getting down to business - Understanding MLC machine learning of LSM6DSOX

Before learning, I referred to justd0's post (https://en.eeworld.com/bbs/thread-1120851-1-1.html). I have to say that it is really powerful. He wrote the tool and made the examples himself. It seems that this is his first time to contact this thing. He really learned by analogy. He must be a master.

After studying the official document: " Usage of MLC on Unico ", follow the steps step by step.

Found it, which means my choice was correct.

I would like to make a special note that for some unknown reason, the board often becomes unresponsive during use. This did not happen a few days ago. Can anyone who knows tell me how to solve this problem?

According to the instructions, there are four steps:

1. Get data

I followed the design process of various great masters, set it up, and then collected data. Unfortunately, the first time it turned out to be an empty table.

Figure 2 Data collected for the first time

What is the reason for no data being collected?

Soon, the reason was found. It was because I didn’t click “ start ”. This is called carelessness and wasted time.

After clicking START , the data is collected.

There is a lot of data.

After collecting the data, we proceed to the next step.

2. Labeling data, filters, and feature calculation

The data should be saved once for each action collected, but I collected many repeated actions at one time, and then there were many repeated actions in it. No wonder justd0 wrote a data processing tool, there is a reason.

Configuration , set it up and get a .Raff file

This step requires weka , download it and use it.

Loading a file

These went relatively smoothly, and then problems arose again.

Start is always gray and cannot be clicked.

It seems that there is something wrong with the collected data.

There is no other way. Let’s go through the process again with justd0 ’s data.

finally,

See the final result.

I'll collect data and do this again tomorrow.

I feel that the engineers at ST are really powerful. Really powerful.

For the unresponsive one, check the device manager to see if there are many serial port devices?

When Unico is connected to the board, it automatically scans the serial port list. I guess this may be the problem.

During use, I often encounter the problem of Unico software freezing and becoming unresponsive. I need to wait a few seconds before it can work again. Sometimes it will exit automatically and I just need to reopen it. It seems like there is something wrong with the software or the computer?
