RT many people ask me, so I put this function that does not involve privacy on my blog. I hope anyone with doubts can see gooogleman:
Hello! After reading your blog, you should be called a senior.
I have been using VB6 for industrial control development for the past few years.

2) Run: run mode. In this mode, only the program can be run and the program cannot be modified.
3) Stop: Stop mode. In this mode, the CPU does not execute user programs, but the computer with Step 7 can read or modify user programs.
4) MREs: memory reset mode. When the switch is released at this position, it will automatically return to the stop position, which cannot be saved.4. S7-300PLC Functions

When you use Hbuilder to develop iOS apps, you are denied the reason why the app was rejected:Your application uses location services, but does not follow the requirements in the iOS HMI Guide to clarify its purpose in the location mode alert.To resolve this issue, specify the intended use of the location in the location licensing mode alert for the user.Find solutions in the official community view of Hbuilder.For a description of the problem, in the
App Store and Play store. This is a very important topic for platform differences and may be very demanding. This guide details how to make sure your app icon looks as good as possible on all devices.Configure the icon for your application
The most straightforward way to provide icons for your application is to provide an icon key in App.json. If you want to be as minimal as possible, then this key is enough. However, the Expo also accepts platform-specific keys under Ios.icon and Android.ico
, for example, at least read through the iOS HMI Guide. ~ios's system does have its own unique considerations and devil details, here is not the apotheosis of Apple, no matter how the Apple small to store a showcase large to the product launch mode has been copied no less than 100 times ah 100 times.

information can still be read after the system has been power-down or restarted. Its bit width is 8 bits, which is smaller than the CPU word length. The article deliberately chooses a memory chip which is inconsistent with the CPU word length, and creates the conditions for the discussion in the following section. The UART completes the conversion of the CPU parallel data transfer to the RS-232 serial data transfer, which can interrupt the CPU after it receives the [1~max_buffer] byte, and ma
in outline style (or both). A solid black speech icon does not have typical features that help you quickly identify it.
It is worth mentioning that the style and color of the icons do not have much effect on the ability of the participants to select the hint icon correctly, except for an icon-lock, which may be slightly recognizable when the lock is in a black white display. I'm not sure why, but the lock icon has an exception on multiple data metrics, it's the easiest icon to be mistaken for

Including the work of its own history, culture, science and technology and many other aspects of the characteristics, so to create an interface of the environment is not to be overlooked a design work, which and we need to turn off the lights when watching a movie is a truth.

In the darts game, the red heart is very difficult to hit, because the red heart is the smallest target on the whole dart plate. Similarly, how do we set the "target" size for a touch device?
Small buttons are more difficult to manipulate than large buttons. When designing a mobile interface, it is best to enlarge the size of the clickable target, which is more beneficial for the user to click. But how much "big" does it take to make it easier for most users? Many mobile developers are also ver

So what's the point of the PPI argument?
By analyzing this mathematical formula we can see that the PPI is related to screen resolution and screen size, so if we have any two sets of these three sets of values, we can get another one.
For example, we learned from the ISO HMI instruction manual that iOS has some general principles: the minimum size of
