A preliminary study on STEVAL-MKI109V3 debugging and logic construction

Since the computer was reinstalled last time, many environments have not been reconfigured. I just took this opportunity to give you a beginner's guide from the perspective of a newbie.

Ps: I don't usually have the habit of organizing my posts, so I should have divided them into several posts... Now that I have organized them all, I will post them in order. Please forgive me.

Project Progress

The above is the initial project plan. As mentioned before, the mechanical structure is confidential for the time being and cannot be made public. I will jump to the progress from week 5 to week 10.

Unboxing

I received a courier from YTO a long time ago, and inside was a delicate little box, as shown below

After opening, the main body of the board is

Mainly include STEVAL-MKI109V3 (motherboard) and LSM6DSOX (daughterboard) on it

Let’s take a closer look

You can see that the motherboard is mainly an STM32F401

The crystal oscillator used is 16MHZ

The material is sufficient and matched with many K33. If I remember correctly, it should be power management.

There are problems that need your correction.

Officially, the daughterboard should be the LSM6DSOXTR IMU.

I will just put the official website's features here and I won't describe them in detail.

Secondly, I would like to reflect a problem here. Please forgive me for not taking good pictures.

The motherboard has too high integration, resulting in the pins on both sides being tilted, and the Dupont wire is not very easy to plug in. The daughter board uses gold-plated pin headers, which is well received. Moreover, the motherboard is not a female header, and uses a chip holder, which makes it very difficult to plug in the daughter board. It would be well received if it could use the female header of Arduino Uno R3!

Software Construction

After reading the main body, let's find the software connection

I heard that the official gave a GUI

But...

I won't say much more.

Please refer to this problem solution

Since the original poster has written it in great detail, I won't say much.

Let me show you some pictures.

Hardware Design

I originally planned to design a board and connect it to a relay.

Finally, the number of design errors is found faster than the proofing...

So the only thing I used in the end was the perforated board.

Here are some pictures

Because of design failure

So even the bottom plate where the control board has relays is not pictured...

The last one is the last helpless move

Really well done
