STM32 embedded technology experimental device

 

Based on the STM32 series embedded chip, starting from the characteristics of embedded experimental teaching, the basic functional experimental circuit adopts an integrated design method. The innovative and expanding experimental circuit adopts an independent module method. Considering the needs of comprehensive design and innovative research experiments. The m--n board comes with the CPU programming download interface. It is a new embedded experimental teaching platform with strong flexibility.

 

2. Features

 

1. Complete experimental guidance

 

For det--led experimental guidance for this experimental box, I believe that you have a professional experimental box and a det--led guidance book, and you will quickly master the ARM embedded technology.

 

2. The functional module is completely independent

 

According to our development experience over the years and the suggestions of the majority of users, this development board adopts the latest concept -each functional module is completely independent, does not interfere with each other, and reduces programming misunderstandings. The l--d -boarding hardware resources and interfaces, and all open I/O ports are opened to the outside, which can simply use short -circuit caps to perform default resource connections (convenient for beginners directly). Any I/O port line of the single -chip microcomputer can easily build your own circuit. With a large number of C -language experimental routines carefully written by the company, users can quickly grasp the principles and practical interface technology of single -chip microcomputer. At the same time, you can strengthen your understanding of the motherboard hardware circuit and be familiar with the hardware circuit as soon as possible.

 

3. Support multiple CPU development experiments

 

Standard STM32F103C8T6 core board. According to customer needs, you can choose other single -chip core boards to achieve support expansion of various CPU chips.

M--n technical features:

1. This experimental device has a variety of basic transmission mechanisms, such as str--ght tooth cylindrical gear mechanisms, worm worm mechanisms, spiral gear mechanisms, str--ght tooth cone gear mechanisms, camwheel, crank slider mechanism, crank rocker mechanism, spiny wheel mechanism, spiny wheel mechanism And the coordination of transmission, ch--n transmission, sliding keys, etc., to form a transmission system for the tooth machine tool, forming a coordinated and coordinated Fan Cheng movement, cutting exercise, feed movement, and knife movement. There are five transmission routes. The ideal example.

2. Teacher machine can insert a str--ght -tooth cylindrical gear with wax rough. The whole journey is about 8 minutes. It can be used to observe the formation process of the entire tooth of the tooth, the operation of each transmission route, and the formation process of Fan Cheng's processing.

3. All transmission institutions are exposed and visible, which is convenient for students to observe.

4. The machine is widely used. In addition to the use of the comprehensive comprehensive curriculum design experimental platform, the teacher machine can also be used to gradually open the principle of tooth cutting. Experimental, mechanical transmission performance comparison experiments.
