How to learn RT Thread, I feel like I don t know much about it, what are the recommended learning me

STM32 can't run full Linux, of course it's good to learn Linux, but it takes a long time to understand it. However, rt-thread is a bit less available now, and it doesn't support GUI yet.

It's easy to learn phonetic transcription first, then grammar.

Let's start with the most basic words like an elementary school student!

After memorizing certain words, you will start to understand some basic grammar knowledge!

I don't think it's a matter of how to learn math in one sentence, but I can say what I think.

I just finished the high school exam last year, and I hope you can adopt my advice. There won't be too many changes in the type of math questions, the key is to do more, do more, the third year of junior high school is very important, and the most important thing is not to be impetuous! Don't always want to ask for help.

The way to do it is to do more and ask more. There is no other way. I'd rather do the questions slowly, but look carefully at every step.

You can't go wrong with fill-in-the-blank choices! If this is not enough, it is recommended to find a math tutoring class, there are quite a lot on the market now, one-on-one tutoring is relatively effective, like 100 education, ** are based on the student's personal situation for the corresponding teaching, so the effect is still good, it is recommended that you try.

If it's easy to learn, almost everyone wants to learn du, make a 3D model by yourself, and then enjoy the joy of success! Edition.

1: Don't read books, don't buy books, there are tutorials on the Internet!

2: There is zhi

Some tutorials look cool, DAO look back.

Yes, but don't do it, no matter how detailed, remember that it's a waste of your precious time!

3: Find some simple, easy-to-learn tutorials on the Internet! The simpler the better!

4: Simple things to repeat and repetition to do simple tutorials, these are two concepts!

5: Just get a good grasp of one or two commands (such as lofting) and take a closer look at our surroundings, which is basically a bunch of geometry!

6: Don't learn everything, look at everything because your ability is limited!

First of all, we must know the basic operation of 3DMAX, in fact, modeling is not difficult to learn, as long as the basic operation will be known, I am looking for a few reference drawings to practice, and the rest is to see how much I have paid and how much I have practiced. You can also find a good school for more systematic learning.

The reason why 3D is called 3D is that a two-dimensional body object is used as a cross-section along a certain path to form a complex three-dimensional object. Different can be on the same path.

The volume of the segment is given different shapes. And the path of this transformation is called loft modeling! Today, Milk Tea will introduce to you the 3dmax lofting modeling in 3dmax basic modeling!

Lofting is a very old and traditional way of modeling. When ancient Greek craftsmen built ships, in order to ensure the size of the hull, they usually made the cross-section of the hull first, and then used brackets to fix the hull and assemble it. The cross-section is gradually raised in the brackets, and the hull of the hull smoothly transitions in the cross-section, a process known as lofting!

The conditions of the stakeout

To implement lofting, you need at least two 2D surfaces, one is the loft path to locate the depth of the lofted object, and the other is the loft section that defines the loft shape.

Loft path

It can be an open or closed curve, but it must be the only curve.

Loft section

It can be an open or closed curve, or a curve or a set of different curves.

In the process of lofting, through the transformation of sections and paths, complex models can be generated, circles can be lofted along a straight line to produce a cylindrical shape, and lofted along a circular path can be used to generate a circular shape.

The lofting technique is used in the creation of a variety of more complex models. Master lofting modeling, whether it is a simple 3D model or a more complex 3D model pattern, you can easily master it.

Most students have experienced the situation of losing marks in the exam because of sloppiness and carelessness, and they can realize this version.

Problem, solution. The decision is half the battle.

Before the exam, you should fully review and prepare properly, so that you will not be impetuous.

During the exam, take a deep breath, calm down, go through the test paper in general, and get a rough idea of the number of questions, question types, and difficulty levels, so that you have a good idea of it.

When answering questions, carefully review the questions word by word, from easy to difficult, even if you can't do it, don't leave it empty.

Inspection, in the exam, the inspection of this link is absolutely unavoidable, and it must be checked from beginning to end. It is best to list the draft according to the order of answers, and the check can be carried out simultaneously with the draft and the test paper. If time permits, you may want to check it several times.

The establishment and use of the "Error Book" recommends that all the questions that have lost marks in the exam should be written down, even if the questions that have lost marks are sloppy, and they should be reviewed several times before the previous exams to remind themselves not to take it lightly.

In addition, practicing calligraphy can adjust the mind, is to calm down, you may wish to insist on writing a page every day, in the long run will definitely increase personal concentration.

Above, for reference.
