How to use the USB flash drive of the peripheral networking server

How to connect the mobile phone to the USB flash drive, no longer afraid of the mobile phone storage space is full.

1. Turn on the phone, find the settings, here a certain model is used for demonstration, and the operation is basically the same.

2. Turn on the Android phone as an example and find the settings.

5. Click to enter and turn on the switch, but it should be noted that this function needs to be restarted before it can be used.

After restarting, the phone can use the external USB flash drive.

There are two types of RS-232 to RS-485 converters on the market, passive and active.

Passive is generally just a conversion, and an active converter not only realizes the conversion of 232 and 485, but also ensures that the two are electrically isolated! Because the 485 line is often long, there is interference on the line, even if there is interference on the 485 line after isolation measures are taken, it will not affect the 232 side! You can take a look at it and refer to it.

Communication ProblemsIn order to be able to achieve what you want the flag to go up and down automatically, you need to have VB control your computer to output two signals: a signal that controls the motor to rotate forward (assuming the flag is raised), and a signal that controls the motor to reverse (assuming the flag is lowered).

In addition, in order to automatically stop the flag when it is raised to the top of the flagpole and lowered to the low end, you can do it in two ways:

1. When the national flag is raised and lowered to the top and low end of the flagpole, a signal is fed back to the computer, and the computer receives this feedback signal to stop the motor from rotating. Here, you can choose the appropriate motor speed to make the national flag lifting time basically consistent with the national anthem time. This will allow the flag to stop at the top and bottom correctly every time.

2. If the requirements are lower, you can also choose a motor with a relatively stable speed to control the running time of the motor through a computer program without feedback signals.

That's where you know how to design automation. It's more complicated. I don't know what kind of control you want to achieve?

First of all, the motor should have a control loop. Also know the position of the flag on the flagpole and so on, these hardware devices are not a simple VB program can achieve. It is recommended that you know some industrial control knowledge.

VB's words are not easy.

Generally, it is necessary to burn ** to the chip.

Win10 questions suggest that you go to a professional place to find the answer, such as the home of soft media win10, the home of soft media IT.

Hello, this depends on whether the administrator has banned the operation of Group Policy, if it is not disabled, it is the best, and the direct compass source connection can be unlocked through the Group Policy operation. But I personally recommend that you talk to the network administrator, and if the company allows it, he shouldn't be embarrassed for you. Companies generally lock the use of mobile devices quietly, because they are afraid that important information will be leaked, you should be careful.
