on someone to see, most of the profit-making stations are more and more exquisite, A nice interface with a friendly HMI is also one of the most important ways to attract users. A good template can leave you a lot of returning users. This can also provide you with a good foundation for the post-business nature of the station.Five. The transformation of the rubbish-type station to the commercial stationGive me an example, of course, in order to prevent
to integrate two can2.0b controllers, enabling developers to develop gateway devices that can connect two industrial standard can (Controller area network) buses. In addition, the new family of microcontrollers also supports Ethernet, USB OTG and can2.0b peripheral interfaces to work simultaneously, so developers can design a gateway device that consolidates all of these peripheral interfaces with just one chip. The STM32 Interconnect series enhances audio performance and uses an advanced phase
1. Setting methodUse SECURECRT to print the Chinese character hint message sent by STM32, which displays garbled characters. Find some links on the internet, coupled with their own groping, finally out of the way to let SECURECRT print Chinese.Here are a few places to set up.1.1 Terminal--->emulation, select the Terminal value on the right is ANSI;1.2 Terminal--->appearance, select the value of current color scheme as monochrome, and select character encoding for Simplified Chinese GB2312.The fo

The function of the system is divided into modules, the hierarchy call relation of the module is established, the interface between modules is determined, the HMI and so on.

The fierce competition, the tightening of product profits, food safety and security, increasingly stringent regulatory requirements and the importance of global market and brand maintenance have put higher demands on enterprises in the dairy industry, and implementing MES will be the only way out for enterprises. Since the "Eleven-Five" manufacturing informatization for the MES, the domestic demand for MES gradually heating up, I am afraid now do not know the information technology mes is not mu
Chapter One introduction to the Knowledge field of 1.2.4 Software engineeringQuestion: Since the domain of software engineering involves so much, how should we learn it well?Answer: The software engineering major is a study of engineering methods to build and maintain effective, practical and high-quality software disciplines.It involves programming languages, databases, software development tools, system platforms, standards, design patterns, and so on. In modern society,Software is used in man
layer, platform service layer and application layer.The gateway is responsible for converting various industrial Ethernet protocols and unifying interfaces.The Platform service layer is responsible for polling, storing, and pushing data. Provide a variety of query, read and write interface.The application layer is mainly human-machine interface (HMI) and various visual function components, such as alarm interface, trend chart, report, chart, place or
level is +5~+12v, and the high level is -12~-5v. A detailed definition of the level interface is shown.Extended:1.RS-485 is the transmission of data in the form of a negative logical differential signal. +2V~+6V indicates low level,-6v~-2V indicates high level;2. Some pins on the chip can be set to the RX and TX ports of the UART. The use of the DuPont line to connect Rx and TX to the peripherals enables information transfer, such as control of the smart LCD (USART

1 IntroductionThe time display function of the desktop Windows system is well known and implemented by the BIOS clock module. You can click the time in the lower-right corner of the taskbar of the desktop system to modify the current time and time zone, and synchronize time with the Internet.Currently, many popular embedded systems such as mobile phones, PDAs, and HMI (Human-Machine Interface Devices) have been transplanted to Microsoft's WindowsCE op
resistance and farther transmission distance are a great advantage.
4, What Is RS-485?RS-485 (EIA-485 standard) is an improvement in RS-422 because it increases the number of devices, from 10 to 32, while defining electrical properties in the case of the maximum number of devices, to ensure sufficient signal voltage. With the capabilities of multiple devices, you can use a single RS-422 port to build a device network. Excellent noise resistance and multi-device capabilities, serial connection s

After solving the basic OS interface, consider the GUI Design.
The common GUI architecture in the embedded industry is as follows:
IDE (fourth-generation scripting language): converts users' designs into third-generation languages supported by RTE (C or C ++)
RTE: responsible for supporting the target OS platform (such as QT, GDI +)
IDE design involves compilation language design, which is not discussed here.
The Design of RTE is discussed below.
RTE is generally divided into two parts
