1.1 Application ScenariosThe interaction object of communication platform includes two aspects: first, interacting with hardware products. Second, interacting with software products. Basically these two aspects, communication platform will generally be used in two scenarios:1) Communication platform application on PCMainly used in the automatic station of the industrial computer, through rs485/rs232, RJ45, 4-20ma and other ways to collect data informa

Bootloader hardware requirement:the hardware required to put the STM32 into System memory boot mode consists of any circui Try, switch or jumper, capable of holding the BOOT0 pin high and the BOOT1 pin low during reset. To connect to the STM32 during System memory boot mode, an RS232 serial interface (example, ST3232 RS232 transceiver) have To is directly linked to the USART1_RX (PA10) and Usart1_tx (PA9) p

input signal, reduce the interference between the signals, and the signal bandwidth is larger than the ordinary D-Sub, which can achieve the best signal response effect.RS232C serial port: RS-232C Standard (protocol) Full name is the EIA-RS-232C standard, where the EIA (Electronic Industry Association) on behalf of the American Electronics Industry Association, RS (ecommeded) Representative recommendation criteria, 232 is the identification number, C represents the latest modification of

In some electrical industries, we can involve RS-232C protocols. As the network expands, all walks of life will apply it to different places. So now the RS-232C Protocol holds some network applications. RS-232-C The RS-232C protocol is the EIA-RS-232C protocol, in which EIA (Electronic Industry Association) represents the American Association of electronics Industry, RS (recommeded standard) represents the Recommendation standard, 232 is the identification number, C Represents the latest version

. Support the number of serial ports, ultra-high cost-effective.Support serial number up to 16 channel, support RS232/TTL interface level switch, serial port rate up to 921600bps. Currently on the market related products support a small number of serial ports, and a single serial port rate is low, similar to support the 16-channel serial port of the product price at least 2000 yuan;2. High performance.The system scheme uses fpga+ full hardware TCP/IP

firm, voltmeter Test, and immediately after the glue gun with glue fixed.2. Connect all the device lines, and in the case of the chassis, the motherboard must be taken down carefully. Prevent it from being broken. Mat Cardboard.3. No metal is allowed in the chassis. For example, accidentally falling into a spiral to prevent a short circuit.4. Install the test after testing, various interfaces. For example, the network port, RS232 serial port, 15-pin

and the receiving level is only 2 V to 3 V, the common mode suppression capability is poor. In addition, the distribution capacitor on the twisted pair wires can provide a maximum transfer distance of about 15 meters, the maximum speed is 20 kb/s. RS-232 is designed for point-to-point (that is, only one pair of receiving, sending equipment) communication, its drive load is 3 ~ 7kb. So RS-232 is suitable for communication between local devices. For more information about the electrical parameter

This USB-to-serial line allows you to easily establish a reliable connection between the serial port (RS232) and USB port. By using the plug-and-play and hot swapping capabilities of the USB interface, you can provide an easy-to-use environment for the serial port (RS232) peripheral devices. Its design allows you to easily connect devices such as mobile phones, digital cameras, ISDN-ta, modem, and various s

Why do I need to generate a pair of terminal device files such as SSH, and a terminal such as tty or serial port or slip only has one device file? This has to begin with the nature of the terminal, in fact, terminals such as serial ports or s that comply with lip rules are essentially the same as tty/console terminals, except that tty device lines are connected by bus such as PCI and AGP, the terminal devices are keyboards, monitors, printers, and so on. The serial port connection terminal is co

Interaction with software products. Generally, communication platforms are used in two scenarios: 1) The communication platform is applied to PCs. It is mainly used in automatic station industrial computer to collect data of hardware devices through RS485/RS2
